Gym Rat — 14 live bonus opens

What Gym Rat has actually done in our bonus hunts

We have opened Gym Rat 14 times across 14 separate bonus hunts between 30 May 2026 and 2 Aug 2026 and recorded every result. Across those 14 opens the median result was 189.75× the bet, against 50× for every slot in our recorded dataset. The biggest single result we have recorded on it is 923.3×. 9 of those 14 opens were 100× or better. 14 opens is a small sample and describes only these recorded sessions — it is not this slot's RTP and it does not predict what your next bonus will do.

Fourteen recorded opens, 64% at 100× or more — above the 30% dataset rate. Median 189.75× sits well above the 50× median; the best so far is 923.3×.

Gym Rat Slot Review

Gym Rat is a slot release from Donut Gaming, and while the wider catalogue of stats and features for this particular listing is still thin on the ground, the name and provider alone give us a decent starting point for what to expect. Fitness- and gym-themed slots have carved out a fun little niche in recent years, typically leaning into dumbbells, protein shakes, sweat-soaked gym rats and a general "no pain, no gain" attitude, and Donut Gaming's take looks set to follow that same energetic, tongue-in-cheek direction.

Theme and gameplay feel

Without confirmed details on the reel layout, paylines or bonus features, it would be unfair to invent specifics that haven't been verified. What we can say is that Donut Gaming has built a reputation for colourful, character-driven slots with a playful sense of humour, and a title called Gym Rat fits neatly into that mould. Expect exaggerated gym-bro or gym-rat characters, bright gym-floor visuals and a soundtrack that leans into upbeat workout energy rather than anything moody or atmospheric.

What the RTP means for players

Gym Rat carries a return to player of 97.7%, which is a genuinely strong figure by modern slot standards — most releases across the industry sit somewhere between 94% and 96.5%, so this puts Gym Rat comfortably above the pack. In practical terms, for every £100 wagered over a large enough sample of spins, the theoretical return sits close to £97.70, meaning the house edge here is noticeably slimmer than average. That's a genuinely attractive number for players who pay attention to long-run value when picking which slot to spend time on.

Volatility and hit frequency

No official volatility rating has been published for Gym Rat at the time of writing, so we'd suggest treating the in-game paytable and information screen as the best source of truth once you load it up — most providers, Donut Gaming included, display this clearly before you commit any real stake.

Max win and betting range

Similarly, no confirmed maximum win or bet range is available for this listing yet. Rather than guess at a headline multiplier that hasn't been verified, we'd recommend checking the paytable directly in the demo or real-money version, where this information is typically laid out clearly alongside the rules for any bonus features.

Verdict

Gym Rat's above-average 97.7% RTP is the standout figure here, and it's reason enough to give the game a look even before the finer mechanical details are confirmed. If you enjoy Donut Gaming's playful house style and appreciate a slot with better-than-average long-run value, it's well worth firing up the free demo at johnessyslots to see the reels, features and betting range for yourself before deciding whether to play for real money.
