Caveman Bob

Three explorable locations — Oasis, Cave and Mountain — anchor Caveman Bob, Relax Gaming's prehistoric-themed release built on a 5x3 grid with 20 fixed paylines. Each location carries its own volatility rating and its own randomly triggered wild feature, and players move between them by progressing through the game rather than choosing freely from the outset.

Wins are formed by landing matching symbols across adjacent reels, and three Shared Features can fire regardless of location: Hand of Bob turns the weakest symbol on the grid into a stronger one and keeps doing so until the resulting win beats the original; Mammoth Respin hands out a free respin loaded with oversized Mammoth symbols, up to 4x4 in size where the current location allows it; and Bob's Wheel offers one spin at a multiplier prize worth as much as 50x the total bet.

Location-specific wilds add a second layer on top of the shared trio. Fire Embers in the Oasis spread up to 13 wild symbols across the grid, and this is the lowest-volatility of the three stops. Stalactites in the Cave turn into between one and five Fully Stacked Locked Wilds at medium volatility. Wild Blizzards on the Mountain are rarer but drop 3 to 15 randomly placed wilds, matching the highest volatility setting in the game. Bob starts in the Cave, with the other two locations opening up as the map is explored.

Caveman Bob pays out at 96.49% RTP overall and runs across bets from 0.20 to 100 a spin. There's no dedicated free spins round — the Shared Features and the three locations' wild triggers are what carry the game's variance instead of a single bonus mode.
