Deep Mine

Felix Gaming keeps 67 games in our catalogue, and this September 2025 release is one of its three-reel builds rather than a five-reel one. Small grid, mid-range swing. The 96.58% return comes through our catalog feed and slotslaunch, and neither route counts as verified in our records.

Three reels, level-3 pacing and a 200-unit stake ceiling

Payline data is missing from our sources for this title — we don't yet carry that field, and inventing it is not an option. Volatility registers 3 of 5. That middle rung normally buys frequency at the expense of size, spin by spin. Stakes run 0.40 to 200. That 96.58% figure sits half a point clear of the 96.08% median we calculate from 9,233 games with recorded returns, and no Megaways, tumbling, buy-in or progressive flag is attached to any of it.

Three-reel layouts suit players who want the maths visible rather than buried under features. The 0.40 to 200 band also makes the game workable at larger stakes, which is unusual for a stripped-back grid.

House margin here is 3.42%, the remainder once 96.58% has been paid back over time. Keep a session limit, and note the 18+ age requirement.
