Fuel The Mule

94% RTP and level-5 volatility on a six-reel grid: Fuel The Mule leads with numbers that ask something of the player. Bulletproof Games, a 27-title studio in our catalog, released it on 27 May 2025 with a Farm theme. The 94% figure comes from slotslaunch and the catalog feed, and it trails the 96.08% median across 9,233 catalog RTPs by 2.08 points — a wider gap than most titles in this tier show.

Six reels, fixed lines, 94% return

The board is 6 reels wide with fixed paylines. Volatility is rated 5 of 5, high. Combined with the below-median return, that produces sessions in which the bankroll drifts down faster on average and the compensating hits are rarer. Stakes range from 0.20 to 100 per spin, a 500-fold spread. No maximum win is on record in our packet, and none of the tracked mechanics — Megaways, bonus buy, progressive, tumbling reels — is enabled. Volatility is one source, slotslaunch, unconfirmed elsewhere.

Who is this for? Players who value the six-reel format and the Farm setting enough to accept a 2-point RTP deficit, and who size their bets to a level-5 swing.

The house edge is 6% of turnover long-run. Decide your limits before playing and keep to them; 18+.
