Caveman Bob

Relax Gaming sets Caveman Bob in a fictional Pliocene, sending its nomadic caveman across three connected locations — Oasis, Cave and Mountain — each carrying its own volatility and its own wild feature, on a 5-reel, 3-row grid with 20 paylines.

Card-suit symbols set as carved gems make up the low pays, while five cartoon characters — a pterodactyl, a wolf, a rhinoceros, a mammoth and Bob himself — sit above them, with Bob worth 25x the stake for five on a line. A wild matching the top symbol's value appears in both single and stacked form.

Three Shared Features can trigger on any spin regardless of which location is active. Hand of Bob converts the lowest-value symbol currently on the reels into a higher one, repeating the conversion until a bigger win than the original has been produced. Mammoth Respin awards a respin populated mostly with colossal Mammoth symbols, sized up to 4x4 depending on location. Bob's Wheel gives a single spin on a multiplier wheel worth up to 50x the total stake.

Each location also carries its own random wild trigger. The Oasis, the lowest-volatility of the three, adds Spreading Wilds of up to 13 symbols via its Fire Embers trigger. The Cave carries medium volatility and turns Stalactites into 1 to 5 Fully Stacked Locked Wilds. The Mountain is the highest-volatility location and its Wild Blizzard trigger is the least frequent of the three but adds 3 to 15 randomly placed wilds. Only the Cave is available from the start; the Oasis and Mountain unlock as players explore.

There's no free spins round in Caveman Bob — the three Shared Features carry the game instead. RTP is 96.49% with medium overall volatility, and stakes run from 0.20 up to 100 per spin.
