About this Slot
Gym Rat is an Animals and Sports themed slot from Donut Gaming with an RTP of 97.7%, high volatility and a maximum win of 25,000x. The game uses 6 reels, 5 rows and Pays Anywhere mechanics across a cascading reel set.
A progressive multiplier climbs to x4096 during wins. A glowing zone on the reels changes how wins are paid, and this zone persists and enlarges as you play. Collections within the zone level up a feature that awards 1 to 3 extra Free Spins alongside zone expansion.
A second feature lands during the bonus round, explodes, and adds a full column to the glowing zone for one spin only.
Three or more Scatter Rats trigger the Scatter Rat Bonus and award 6 Free Spins. During this round, the multiplier is sticky and the glowing zone persists across all spins.
Four or more Scatters trigger the Super Bonus and also award 6 Free Spins, but every win in this round doubles the multiplier instead of using the standard progressive climb.
Chance costs 3x per spin and raises the chance of triggering a bonus feature. Bonus costs 100x bet and awards 6 Free Spins with a sticky multiplier and persistent zone. Super Bonus costs 200x bet and awards 6 Free Spins where every win doubles the multiplier.
Cheatcode Spin costs 500x per spin and guarantees an initial win. Cheatcode costs 1,000x per spin, awards 8 Free Spins and starts the multiplier at x128, doubling it with each subsequent win.
