Slot Glossary
27 terms every slot player should know — explained with 12 Fortune Signs examples where relevant. No marketing jargon.
Autoplay
A setting that spins the reels automatically for a set number of rounds. You pick how many spins and optional stop conditions (like stopping on a bonus trigger or when your balance drops below a threshold). Useful for grinding through base game spins without clicking every time.
Base Game
Regular gameplay before any bonus features trigger. Most of your spins happen here. In medium-high-volatility slots like 12 Fortune Signs, the base game delivers moderate returns through Expanding Wild substitutions while you wait for the Free Games or Pin Win triggers.
Bonus Buy (Feature Buy)
Lets you skip the base game and jump directly into a bonus round for a fixed cost. In 12 Fortune Signs, the Bonus Wheel buy is priced at 80x your bet — it lands on Free Games, Pin Win, a Mystery prize, or the Grand 1,000x segment. Not available in all jurisdictions; the UK bans it entirely.
Cascading Reels (Tumble)
After a win, winning symbols disappear and new ones fall into place. This can chain multiple wins from a single spin. 12 Fortune Signs doesn't use cascading reels — it relies on Expanding Wilds and sticky symbols during Free Games instead.
Cluster Pays
A win mechanic where matching symbols need to form a connected group (cluster) rather than lining up on a payline. Typically requires 5+ matching symbols touching horizontally or vertically.
Dead Spin
A spin that returns absolutely nothing — zero payout. In medium-high-volatility slots like 12 Fortune Signs, dead spins are common between feature triggers. That's not a bug; it's how the math model works. Budget accordingly and don't chase losses after a dry streak.
Expanding Wild
A Wild that grows from a single position to cover the full reel — all 3 rows on a 5x3 grid. In 12 Fortune Signs, an Expanding Wild only lands on reels 2, 3, or 4 (the middle three). During Free Games it also carries a random multiplier between 2x and 10x. Two expanded Wilds on the same spin compound multiplicatively: 5x × 3x = 15x on overlapping paylines.
Feature Trigger Rate
How often a bonus feature activates, usually expressed as '1 in X spins.' In 12 Fortune Signs, Free Games trigger roughly 1 in 150 base game spins (3 scatters on reels 1, 3, 5). Pin Win triggers about 1 in 200 spins. The 4-scatter Bonus Wheel is rarer at 1 in 400. You can find these stats in the game's info panel from Amigo Gaming.
Free Spins
Bonus rounds triggered by landing scatter symbols. 12 Fortune Signs calls them Free Games — land 3 Zodiac Wheel scatters on reels 1, 3, and 5 to win 12 spins. Premium zodiac symbols that form part of a win turn sticky and lock in place for the rest of the round, building dense winning combinations across remaining spins.
Hit Frequency
How often a slot lands any winning combination. A 25% hit frequency means roughly 1 in 4 spins pays something. Medium-High-volatility slots like 12 Fortune Signs balance moderate hit frequency with the bigger payouts concentrated in Free Games and Pin Win triggers.
Max Win
The absolute maximum a slot can pay on a single spin, expressed as a multiplier of your bet. 12 Fortune Signs caps at 7,500x. Once hit, the round ends immediately regardless of remaining features. Most players never reach this — it's a theoretical max win.
Max Win Cap
The absolute ceiling on a single spin's payout. Once reached, the game stops the round immediately — even if you had remaining free spins with multipliers building. 12 Fortune Signs caps at 7,500x. The round ends, your balance updates, and you're back to base game. This cap protects the casino's liability.
Megaways
A mechanic by Big Time Gaming where the number of symbols per reel changes each spin, creating up to 117,649 ways to win. 12 Fortune Signs uses 30 Lines on a 5x3 grid — a fixed payline system, not Megaways.
Multiplier
A value that multiplies your win. A 10x multiplier on a $5 win = $50 payout. In 12 Fortune Signs, multipliers come from Expanding Wilds during Free Games — values are 2x, 3x, 5x, or 10x. Two expanded Wilds compound multiplicatively, so a 10x × 10x combo on a single payline pays 100x. That's how the 7,500x max becomes mathematically reachable.
Paylines
Predefined lines across the reels where matching symbols must land to form a win. 12 Fortune Signs has 30 Lines on a 5x3 grid. All lines activate automatically — you can't reduce the number.
Paytable
The reference chart showing what each symbol pays for different combination lengths (3, 4, or 5 of a kind). Access it through the game's info or settings menu. Premium zodiac symbols (Dragon, Tiger, Phoenix) always pay more than card symbols (A, K, Q, J, 10).
Pin Win
A pachinko-style bonus inside 12 Fortune Signs. Land 3 Pin Win symbols on reels 2, 3, and 4 and a pin board appears. Zodiac coins drop from the top, bounce through pegs, and land in value slots from 1x up to 500x your bet. You get 3 drops minimum, with extra drops awarded if a coin lands in the "Extra Drop" slot. Average Pin Win total: ~45x.
RNG (Random Number Generator)
The algorithm that determines every spin outcome. Certified by independent labs (like eCOGRA, iTech Labs, GLI) to ensure fairness. Each spin is completely independent — previous results have zero influence on future ones. There's no such thing as a slot being 'due' for a win.
RTP (Return to Player)
The theoretical percentage of wagered money a slot returns over millions of spins. 12 Fortune Signs has an RTP of 96.10%. That doesn't mean you'll get back that exact percentage in your session — it's a long-term statistical average. Short sessions can deviate wildly in either direction.
Scatter
A special symbol that triggers features regardless of its position on the grid — it doesn't need to land on a specific payline. In 12 Fortune Signs, the Zodiac Wheel scatter triggers Free Games when 3 land on reels 1, 3, and 5. Land 4 scatters anywhere and the Bonus Wheel opens directly.
Session Variance
The gap between your actual results and the theoretical RTP. 12 Fortune Signs has 96.10% RTP, but a 500-spin session can return anywhere from 40% to 180% of your wager. That's normal. Don't judge a slot's fairness from a single session — you need thousands of spins for results to converge toward the published RTP.
Sticky Wild
A symbol that stays in place for multiple spins instead of disappearing after one round. 12 Fortune Signs doesn't use traditional Sticky Wilds — instead, during Free Games any premium zodiac symbol that forms part of a win locks in position for all remaining spins. By spin 8-10, portions of the grid can be filled with locked Dragons, Tigers, or Phoenixes.
Volatility (Variance)
How a slot's payouts are distributed. High volatility = rare but large wins, long dry spells. Low volatility = frequent small wins, steadier balance. 12 Fortune Signs is rated Medium-High volatility. Expect a balanced mix of base game returns through Expanding Wilds and bigger hits when Free Games or Pin Win finally trigger.
Ways to Win
An alternative to paylines where matching symbols on adjacent reels (left to right) count as wins regardless of row position. A 5×3 grid with ways-to-win has 243 possible combinations. 12 Fortune Signs uses 30 Lines — fixed paylines, not ways-to-win.
Wild
A symbol that substitutes for any regular symbol to complete winning combinations. It doesn't replace scatters or special bonus symbols. In 12 Fortune Signs, Wilds appear only on reels 2, 3, and 4 and always expand to cover the full reel. During Free Games they carry a 2x–10x multiplier on top of the substitution.
Win Distribution
How a slot's total payouts are spread across different win sizes. Medium-High-volatility slots like 12 Fortune Signs sit between top-heavy and even — a meaningful share of returns comes from base game Expanding Wilds, but the largest payouts concentrate in Free Games with stacked multipliers and the Pin Win 500x slot. Neither extreme; a balanced shape.
Bonus Buy Restrictions
Some countries ban the ability to purchase bonus rounds directly. The UK prohibits bonus buy since October 2021. Sweden caps bet sizes. Other markets have similar rules. In 12 Fortune Signs, the 80x Bonus Wheel buy may be greyed out or hidden depending on where you're playing.
