Diamond Force Slot by Crazy Tooth Studio

Four superhero characters appear as full-stack symbols, each contributing a different modifier when the Team-Up Feature triggers. The blue hero adds a 5x multiplier, the red hero brings 3x, the purple hero carries 2x, and the green hero loads the mini-reel with high-value cash prizes. Land 3 or 4 stacked heroes simultaneously, and the game builds a temporary gameboard from those positions - containing only credit values and multipliers. Multiple multipliers compound: a 5x and 3x landing together produce a 15x total on collected cash.

The bonus round needs a different combination - two or more stacked heroes alongside the Full Stack Bonus symbol on reel 5. It starts with just 3 spins on a similar mini-reel layout, but extra spin tokens (+1, +2, +3) extend the round up to 20 total spins. Multipliers keep stacking throughout, so a long bonus session with several 5x hits compounds into serious totals.

The paytable is completely flat. All four heroes pay 0.2x for any combination length - three, four, or five of a kind. Card symbols all pay 0.1x. This concentrates win potential into the Team-Up features and leaves the base game feeling thin between triggers, despite frequent small hits from the Any Adjacent Pays system.

A Paytable Achievements tracker marks off symbol combinations as you land them during a session, adding a completionist layer without affecting payouts. Cosmetic, but it gives longer sessions a sense of progress.
