Slot Mechanics
Browse the systems that define how slot games produce and evaluate wins. Each mechanic page explains how it works and lists games that use it.
-
Reel Switching Reel Switching changes the active reel set during play, so base game, enhanced modes and bonuses each spin on differently composed strips.
- Connected Reels
Connected Reels tie parts of the grid together so symbols, wilds or reel states carry from one connected area to another during play.
- Synced Reels
Synced Reels randomly link two or more reels for a spin so they display identical symbol strips, sharply raising the chance of long combinations.
- Split Symbols
Split Symbols put two or more symbols into one reel position, so a five-reel game can pay combinations far longer than five symbols.
- Multi-Grid
Multi-Grid slots run two or more playing areas simultaneously on one bet, often letting wilds, symbols or wins carry across the boards.
- Dynamic Grid
Dynamic Grid describes grid-based slots whose playing field changes shape during play, unlocking cells, zones or whole sections as the game progresses.
- Dynamic Reels
Dynamic Reels is the umbrella for slots whose reel count or reel heights change during play, whether randomly per spin or as a result of wins.
- Expanding Reels
Expanding Reels enlarge the playing grid during a spin or bonus, adding rows or reels up to a defined maximum and increasing the ways count.
- Gigablox
Gigablox is a Yggdrasil mechanic where oversized symbol blocks land on the reels and count as the equivalent number of regular symbols.
- InfiniReels
InfiniReels starts with a small grid and adds a new reel after every win, letting a single spin extend the layout with no fixed cap.
