Grug Make Fire — RTP, volatility and max win

Grug Make Fire from Hacksaw Gaming is set in the Stone Age, where the caveman Grug tries to light his very first fire among dinosaurs and bears. Energy symbols fill a meter and push features up a level, while wilds with multipliers boost the wins they touch.

Grug Make Fire is a tongue-in-cheek prehistoric adventure: dinosaurs and bears fill the screen, with the caveman in the middle who, as the title says, wants to make fire. Hacksaw Gaming gives Grug a 5×4 grid holding 14 paylines, and spins cost anywhere from €0.10 to €100, covering small and high bets alike. Grug Make Fire was released on June 9, 2026, making it one of the newest titles in the catalogue.

The five reels and four rows carry 14 paylines. A line pays once matching symbols run from the left along it. Wilds fill gaps, and since they can carry multipliers, any line running through such a wild pays more. Scatters do not count for the lines; they are the route into the free spins.

Several mechanics work together in the base game: symbol swap transforms symbols on the grid, symbol removal takes individual symbols out of play, and random multipliers boost wins on the spot. Grug Make Fire also gathers energy symbols, and a full meter triggers a level-up that strengthens the features.

Scatters lead to free spins, more scatters add extra spins, and the multiplier wilds stay in play there too. The bonus bet raises your stake for better odds of reaching the free spins, and the feature buy starts them straight away.

Since the bonus bet on Grug Make Fire raises the stake to reach the free spins more often, the inferno slots with a bonus bet are the natural next comparison.
