Fire Chilli Slot by Zillion Games

Three progress bars shaped like chilli piles sit above the grid - DOUBLE (red), MULTI (green), and EXTRA (yellow). Each fills as its matching chilli symbol lands during regular play. When a bar completes before the Bonus Game triggers, that feature stays active for the entire bonus round. All three can stack simultaneously.

DOUBLE adds a second 5x3 grid beside the first one. Bonus coins that appear get duplicated on both fields, each with its own respin counter. MULTI randomly assigns x2, x3, or x5 multipliers to individual bonus coins during respins, and if the same coin gets hit again, multipliers compound - x2 then x3 becomes x6. EXTRA bumps the respin counter from 3 to 4, and each new coin resets to 4 instead of 3.

Running all three features at once is where the 3000x ceiling lives. Two grids collecting duplicate coins, each coin potentially carrying stacked multipliers, with an extra respin cushion to keep things rolling. Four jackpot tiers round it out: Grand (1000x), Major (100x), Minor (30x), Mini (15x). Buy Bonus skips straight to the Hold and Ring trigger.
