Dead Rider's Trail Slot by Relax Gaming

The 6x6 reel sits half-buried under grey stone blocks every time the round starts. Anywhere from 3 to 24 of them block symbol positions on any given spin, and they're not paying tiles - they're obstacles. Land a winning ways combination and the cascade kicks in: the matched symbols disappear AND every stone block touching them (left, right, above, below) gets blown out with them. New symbols drop, the chain repeats, and the goal of every base spin is the same. Clear the entire grid of stone, and the Feature Wheel spins.

That wheel hands out one of four prizes: 4 Free Spins, 7 Free Spins, the Bonus Trail, or the Super Bonus Trail. If it lands on Free Spins, an unusual gamble option appears. You can ditch the spins entirely for a coin-flip at the Bonus Trail itself. The odds are explicit: 33% if you won the 4-spin tier, 52% if you won the 7-spin tier. So the small Free Spins prize doubles as a lottery ticket for the bigger one.

Free Spins themselves come with bombs strapped to some of the stone blocks. Adjacent wins detonate them, and a detonated bomb covers its entire reel and rewrites every symbol on it to whichever pay would generate the largest win. Clear all stones during a free round and you get +3 extra spins on top.

The Bonus Trail is where this game from Relax Gaming gets weird in a good way. It's a board game. A 39-tile track with three side branches, a pawn that moves 1 to 6 steps per turn, and a fuel meter starting at 3 units that drops one per move. Tiles hold cash values, refuel cans, and trucks - silver trucks fire one-shot features (Sniper, Two-Knife, Payer, Cash, Collect, Shoot Back), gold trucks lock in persistent versions that keep firing on every subsequent landing. Complete a lap and every Normal Tile gets +3x, plus you refuel by 1. Run out of fuel and the round ends. Normal Tile cap is 1,000x, the trail itself caps at the full 50,000x. Super Bonus Trail upgrades the silver truck closest to the start into a gold one, which heavily skews the persistent-feature draw.

The art is Wild West outlaw country. Wanted-poster character symbols, a saloon-frame border, dusty ochre cliffs behind the reels, and the same gritty palette you'll find on Wanted Dead or a Wild. Three direct entries via Buy Bonus: Feature Wheel at 50x, Bonus Trail at 90x, Super Bonus Trail at 250x.
