Basics of Stack ‘Em
Stack ‘Em is a 5×6 grid slot game developed by Hacksaw Gaming. Unlike traditional slots, it uses cascading symbols and cluster pays instead of fixed paylines. Winning clusters of five or more matching symbols trigger a cascade mechanic, removing winning symbols and letting new ones fall in.
Core Mechanics
- Symbols fall from top to bottom via cascades
- Wins form from clusters of 5+ matching symbols horizontally or vertically
- Wild symbols substitute for any regular symbol
