Slots Glossary for Alberta Players

This slots glossary explains the words used in game rules, paytables and result screens. Use the alphabet links to find a term, then follow the linked guide for worked examples. A familiar label does not establish the complete rule: the exact title, mode, cash stake and applicable game information still matter.

The definitions cover general vocabulary and clearly identified publisher examples for Alberta readers. They do not confirm that a named game appears in every regional casino lobby. For balances, verification and payment vocabulary, use the separate Casino Terms guide.

The selected brands appear in the AiGC directory checked November 1, 2026. Payment summaries retain operator information checked October 30. These cards link to account reviews; they do not assign one RTP or volatility rating to a casino. Visit links may earn a commission; see our affiliate disclosure.

Keep game and account information separate. A payment timeframe does not establish a game’s paying rules or return. No paid spin or cash transaction was tested for this glossary.

A–B: active lines, base games and bets

Active payline

A defined line included in the current wager. Some games have fixed lines; others permit selection. Read how the full stake is calculated and which paths are evaluated. An attractive matching pattern outside the qualifying path may not pay.

Adjacent symbols

Symbols occupying neighbouring positions under a game’s specified connection rule. Cluster games can define adjacency differently, so do not assume diagonal contact qualifies. The required group size and eligible symbols also belong to that rule.

All ways

A paying format that evaluates qualifying combinations across specified reels instead of a selected set of line paths. The phrase does not mean every arrangement wins. Read the starting reel, direction, minimum match and any excluded positions.

Autoplay

A control that, where available, starts a series of rounds under selected conditions. Availability and settings depend on the product and regional version. Repeated automatic rounds still have a complete cost; the control does not provide a different return guarantee.

Base game

The ordinary game state from which additional features may trigger. Its rules can differ from a free-spin or held-symbol sequence. A rating or percentage describing one state should retain its scope when the product supplies separate information.

Bet or wager

The amount committed to the defined round. Use the complete cash debit, including selected extras, rather than reading a coin value in isolation. See how to play slots for the basic controls.

Bet level

A game control affecting the selected stake according to that title’s formula. It may interact with units, denomination or a fixed layout. Read the resulting cash amount after changing it; the label is not a universal formula.

Bonus feature

An additional game sequence or mechanism, such as extra spins, a collection process or held-symbol play. This is different from a promotional account offer. The trigger, rules and final award come from the title’s feature instructions.

C–D: cascades, credits and denominations

Cascade

A sequence in which qualifying symbols are removed or replaced and the game evaluates the resulting layout again. Several evaluations can form one paid round. Read whether a multiplier changes between steps and where the complete round total appears.

Cluster

A qualifying group of connected symbols. Play’n GO’s original Reactoonz provides a publisher example: its seven-by-seven grid pays clusters of five or more matching aliens. That example does not define every cluster game’s adjacency rule or establish Alberta availability.

Coin value

The cash value assigned to one unit where a game uses coin-based pricing. The full stake may include several units or lines. In an invented example, twelve five-cent units cost 60 cents; a five-cent label alone would omit most of that price.

Collect

A product-specific instruction or feature that gathers stated values or settles an amount. Read what it collects, from which symbols and at what stage. A collect symbol and a button that banks an award can describe different actions.

Credit

Either a unit used by the game or an amount awarded back, depending on context. Identify its cash value and whether a displayed figure is a subtotal or final credit. Practice credits also differ from withdrawable account money.

Demo play

A practice version using non-withdrawable credits. It can help you find controls and read feature messages, but its selected outcomes do not forecast a cash session or certify a later account game’s configuration. See free slots.

Denomination

The cash scale used for a unit of play. A smaller denomination does not independently establish lower volatility or a better return. Read the complete stake, applicable settings and game rules as separate fields.

E–F: expanding wilds, features and free spins

Expanding wild

A wild that extends over additional positions under a stated condition. NetEnt’s Starburst description provides a publisher example involving an expanding wild and a respin. Read the exact release’s substitutions and trigger rather than assuming every expanding wild behaves identically.

Extra reel

An additional displayed reel or strip with a specific role in the game’s evaluation. Its presence does not automatically add a fixed number of paying combinations. Read which positions it serves and how the title includes them.

Feature buy

A separately priced entry into a stated feature, where the applicable version offers it. Read the complete debit and mode-specific information. A displayed base-stake unit is not necessarily the purchase price. Availability must be checked in the actual regional product.

Feature trigger

The condition that starts an additional mechanism. It could involve specified symbols, a meter or another described event. Triggering a feature does not itself identify the complete cash credit or guarantee a profit on the original round.

Final credit

The complete amount returned when the round and its included features settle. Count it once. If it already contains earlier cascade or feature subtotals, adding those messages again would overstate the amount actually received.

Free spins

Additional spins awarded under game rules, or a promotional allocation under separate account conditions. Identify which meaning applies. Game-triggered spins can use different symbols, counters or multipliers; a promotional allocation needs its own eligibility and withdrawal wording.

G–H: game records, hits and Hold and Win

Gamble feature

An optional game mechanism that risks a stated amount or entitlement for another outcome. Read the amount exposed and the consequence of each result. Its presence should not be interpreted as a method for recovering earlier losses.

Game ID

An identifier for the title or product version. It differs from the reference for one particular round. Record both when investigating a result, together with currency, time and selected mode. Similar names can identify different releases.

Grid

The arrangement of displayed symbol positions, often described through columns and rows. The dimensions alone do not reveal the paying rule. A grid can support paylines, counts, clusters or another title-specific method of evaluation.

Hit frequency

The probability or measured frequency of the event defined as a hit. The definition may include credits below the stake. It is different from RTP, profitable-round frequency and the chance of a particular feature. Keep the source’s definition attached.

Hold and Win

A broad feature label commonly involving specified symbols retained while other positions are evaluated again. Counters, resets and collection rules vary by title. The Hold and Win guide compares examples without imposing one universal respin count.

House edge

The theoretical loss rate complementary to RTP on the same model and accounting basis. A hypothetical 95% return corresponds to a 5% edge. That is an average relationship, not the operator’s guaranteed share of each individual round.

I–L: information panels, jackpots and locked symbols

Information panel

The in-game area containing rules, paytable details and other disclosed settings. It may use an information icon or menu. Record full wording, including mode qualifiers and footnotes, rather than copying a bare percentage from a promotional tile.

Jackpot

A named award or prize pool with defined eligibility and trigger conditions. Its label alone does not establish whether it is fixed, progressive, local or shared. A displayed amount also does not reveal the probability of winning it.

Locked symbol

A symbol retained in its position during the stated feature or sequence. Read how long it remains and whether it carries a cash value, multiplier or substitution role. Similar artwork does not establish identical retention rules.

Loss on a round

The excess of the complete cost over the complete returned credit. In an invented 60-cent round paying 20 cents, the net loss is 40 cents. A positive animation does not change that accounting result.

M–N: maximum wins, Megaways and net results

Maximum win

An upper award limit under stated rules, often expressed against a defined bet amount. Read the mode, currency scale and whether all components are included. The endpoint does not reveal its probability, the average return or the casino’s withdrawal schedule.

Megaways

A Big Time Gaming mechanic involving changing reel configurations and title-specific ways calculations. BTG describes Vegas Megaways as a six-reel example offering up to 117,649 ways. That maximum is specific to the example, not every Megaways title. See the Megaways guide.

Multiplier

A factor applied to a stated amount. Identify whether the base is a line bet, total stake, symbol value or accumulated subtotal. The same “5x” label produces different cash amounts when those bases differ.

Near miss

A losing display that appears visually close to a paying combination. Appearance does not establish that the next result is more likely to win. Read the actual qualifying conditions and avoid treating closeness in the artwork as a partial entitlement.

Net result

The complete returned credit minus the complete cost for the defined round or activity. On an invented 60-cent round, a $1.80 final credit produces a $1.20 gain. A withdrawal is a separate movement of account funds.

O–P: observed return, paylines and progressive pools

Observed RTP

The ratio of recorded game credits to recorded stakes in a defined sample. It describes what happened in that sample and can exceed 100%. It does not independently certify the theoretical model or identify the next outcome.

Paying direction

The direction and starting position required for a qualifying combination. A title might specify a starting reel or another pattern. Read its actual rule; familiar symbol artwork does not establish that a match pays in both directions.

Payline

A defined path through symbol positions used to evaluate specified combinations. A line can be straight or shaped. Its award requirements and bet basis belong to the paytable. More lines do not automatically establish a higher RTP.

Paytable

The information describing qualifying awards and their values. Read the units, required matches, exclusions and multiplier bases. It works alongside the wider rules, which can describe feature triggers, maximum awards and final settlement.

Persistent feature

A mechanism that preserves a stated state, such as held symbols or a meter, across the specified sequence. Its documented state can matter to the next step. That differs from assuming unrelated ordinary losses make a fresh round due.

Progressive jackpot

A prize pool that changes under its funding and award rules. Check contribution, eligibility, seed, ceiling and payout conditions where disclosed. The progressive-jackpot guide explains these fields separately from base-game awards.

Q–R: qualifying stakes, random outcomes and RTP

Qualifying stake

A stake meeting the conditions of a particular feature, jackpot or account requirement. Its scope must be stated. A cash amount suitable for ordinary play does not, by itself, establish every additional entitlement.

Random number generator, or RNG

A process supplying random inputs that the game maps to outcomes under its design. Random input does not mean every displayed symbol or award is equally likely. UK Gambling Commission RTS 7 provides technical background on unpredictable output and mapping.

Reel

A displayed column or sequence of symbol positions in a reel-based game. Modern presentations can contain variable heights, extra strips or other structures. Reel count alone does not define the complete outcome probabilities or price.

Reel strip

A representation of symbol positions used within a reel design. What is visible on screen is not necessarily a complete description of those positions or their probabilities. Do not calculate a jackpot chance simply by counting symbols in one screenshot.

Respin

A further evaluation described by the game, sometimes retaining specified symbols or positions. Read whether it is included in the round and which trigger or counter controls it. The word alone does not establish a separate cash price.

Retrigger

An event that extends or restarts a feature under its rules, such as adding spins or resetting a counter. Identify the required symbols and any limit. A retrigger condition can differ from the event that originally opened the feature.

Return to player, or RTP

The theoretical average return relative to stakes for a specified model. A hypothetical 96% RTP does not mean 96 winning spins in one hundred. The RTP guide explains turnover, observed samples and configuration differences.

Round reference

The identifier for a specific game event. Preserve it with the title, time, currency, stake and final credit when contacting support. It is different from a payment transaction reference and from the identifier for the game itself.

S–T: scatters, stakes, sticky wilds and tumbles

Scatter

A symbol evaluated under a specific scatter rule, which may award a credit, start a feature or do both. Read the required count and permitted positions. “Anywhere” should be used only when the game actually specifies it.

Stake

The complete amount committed to the round or separately priced action. Check cash rather than only coin units. A purchased feature and an ordinary spin may have different complete costs even when both display the same base-stake unit.

Sticky wild

A wild retained for the period described in the feature. Its duration and substitutions depend on the title. It should not be assumed to remain indefinitely or to replace scatter and jackpot symbols without an explicit rule.

Stop button

A control whose effect must be read in the product instructions. A change to animation or presentation does not establish player control of random selection. Do not treat a visually timed press as a documented probability advantage.

Symbol count

A paying rule based on a stated quantity of matching symbols in permitted positions. Pragmatic Play’s Sweet Bonanza 1000 provides an example involving symbol counts and tumbles. That exact release should not be confused with other similarly named versions.

Tumble

A title’s name for a replacement-and-reevaluation sequence, often comparable to a cascade. Read how winning symbols disappear, how positions refill and whether multipliers apply to one evaluation or an accumulated amount. Count the final credit once.

Turnover

The total staked, including returned credits used again. It is different from deposits, withdrawals and the starting balance. An invented ten 40-cent rounds create $4 of turnover regardless of which credits those rounds return.

U–Z: units, variance, volatility, ways and wilds

Unit

A measurement whose cash value must be defined. It may mean a game credit or a separately chosen budgeting amount. Keep the definition with any calculation. Ten units at two cents each equal 20 cents, not ten dollars.

Variance

A mathematical measure formed by weighting squared distances from an average. Its square root is standard deviation. The volatility guide uses invented distributions to explain the relationship without estimating a real game’s undisclosed mathematics.

Video slot

A slot presented through a video interface. The label does not establish its paying format, RTP or volatility. The video-slots guide compares paylines, ways, symbol counts and clusters within different presentations.

Volatility

The spread of possible results around their average, commonly represented mathematically through standard deviation. Read the source’s category and scope. A high or low label does not predict the exact length or profitability of a session.

Ways

Qualifying symbol combinations evaluated across the specified reels and positions. A displayed ways total describes the format, not the number of wins guaranteed in a round. Direction, minimum matches and exclusions still need the actual rules.

Wild

A symbol substituting under stated conditions. It may expand, remain sticky or carry a multiplier, but those are additional rules. Check which symbols it cannot replace. The slot-features guide explains the distinctions.

X bet, or x-bet notation

A multiple of the bet amount defined by the source. Identify whether it means the total stake or another base. In an invented example, 20x a 40-cent total stake is $8; the notation does not reveal its probability.

Reading several terms in one round

For an invented example, a game uses a 40-cent total stake. One evaluation credits 30 cents and a second credits 50 cents. If a stated three-times multiplier applies to the combined subtotal, the final credit is $2.40: (30 cents + 50 cents) × 3. The net gain after the 40-cent cost is $2.

The terms identify different parts of that calculation: stake, evaluation, subtotal, multiplier, final credit and net result. Adding the 80-cent subtotal again would double-count an amount already included. This is a calculation exercise, not a rule, price or likely outcome for a real game.

For a session record, use actual stakes, complete credits and account movements. Our session ledger organizes balances; the withdrawals guide covers moving eligible money out of the account.

Glossary questions

Does a term have the same rule in every slot?

No. A general definition helps you find the relevant instructions. The exact title and mode define the qualifying count, positions, price and awards. A familiar feature name does not establish identical rules or availability.

Does a win mean a profit?

A positive credit can be below the complete stake. In the invented sixty-cent round returning twenty cents, the loss is forty cents. Compare the full final credit with the full cost, then use complete balances for a session result.

Can I use a maximum award to calculate RTP?

No. A maximum is an endpoint. RTP also depends on the probabilities and amounts across the mathematical model. A screenshot, selected winning clip or advertised top award does not supply the missing distribution.

Is RTP the same as hit frequency?

No. RTP measures return relative to stakes; hit frequency counts a defined event. That event can include credits below the stake. Neither a hit percentage nor a return percentage by itself gives the frequency of profitable rounds.

Does a random game make every symbol equally likely?

No. Random inputs are mapped to game outcomes under the design. Symbols and awards can have different probabilities. Counting visible symbols in one screenshot does not reveal the complete reel design or establish a jackpot chance.

Is the coin value the complete price of a round?

Not necessarily. Units, lines, bet level and selected extras can affect the complete cost. In the invented example, twelve five-cent units cost sixty cents. Read the final cash stake rather than treating the five-cent unit as the whole price.

Should I add feature subtotals to the final credit?

Only when the rules and result record show they are separate amounts. In the invented example, the eighty-cent subtotal is already included in the $2.40 final credit. Adding it again would count the same award twice.

Does one casino have a single RTP for all its slots?

An individual title and configuration have their own information. A casino name, payment method or withdrawal timeframe does not establish one return for every game. Check the exact release, selected mode and applicable game rules.
