Overview
DuoMax is a Game Engagement Mechanic (GEM) from Yggdrasil. As the “Duo” in the name suggests, multipliers build up separately in two tracks, one on each side of the reels. In this slot that pays both ways, which multiplier grows depends on the direction of the win.
The first game was Florageddon! DuoMax, released in October 2022 for the Halloween season. It had 5×3 reels with a pays-both-ways 243 ways structure.
Win direction and multipliers
DuoMax games are built around tumbling wins, where winning symbols disappear and new symbols drop in. Each time a tumble win happens, the multiplier beside the reels goes up, and the win direction decides which side rises.
| Win direction | Multiplier that increases |
|---|---|
| Left → right | Left multiplier |
| Right → left | Right multiplier |
| Both sides (e.g., 5 of a kind) | Both multipliers |
So if wins keep coming in only one direction, only that side’s multiplier grows while the other stays as it is. To raise both at once, you need a win that fills all five reel positions.
Florageddon! extras
- Streak meter: The meter above the reels counts consecutive tumble wins within a single spin. At 4 in a row, it gives one of the following: a multiplier increase, double wilds, a wild stack, or an extra chance.
- Wild add: Each time a tumble win happens, one wild is added to the reels.
- Free spins: Triggered by 3 or more free spins symbols, and the multipliers do not reset between spins. At the start, you can gamble to try to extend them to up to 16 spins.
- Golden Bet · Bonus Buy: Raise your bet to improve the odds of special rewards, or buy the bonus directly in permitted regions.
How DuoMax changed from game to game
Juiced DuoMax (November 2023)
A 5×3 pays-both-ways game from Bulletproof Games. A character stands on each side of the reels, and each character’s multiplier rises with every win, up to 2,000x. A 5-of-a-kind win raises both multipliers together. As wins pile up, the drink gauge beside the reels fills, and when it is full, free spins begin.
Chilli Super Stars (December 2025)
Made by Boomerang Studios, this game combines DuoMax with Gigarise, where the reel height grows, and OnlyWins, where only winning spins use up free spins. The ways expand from 243 up to 7,776.
