Caveman Bob Slot Overview

Caveman Bob is a prehistoric video slot from Relax Gaming, built around a 5x3 reel layout and 20 fixed paylines. The game follows Bob through three different worlds, with each setting changing the wild feature.

The slot’s main structure is based on random feature triggers rather than a standard free spins round. Bob’s Wheel, Hand of Bob and Mammoth Respins can all appear during play, while the Cave, Oasis and Mountain worlds each apply their own version of wild-symbol behaviour.

Cave World Design

The Cave world uses a darker underground setting with rocky textures and stalactites.

Oasis World Design

The Oasis world adds warmer colours, open scenery and a more balanced visual layout.

Mountain World Design

The Mountain world uses colder colours and snowy scenery.

How to Win at Caveman Bob

Here’s a guide to all the different ways to win when playing the Caveman Bob slot.

Gameplay Flow & Systems

Caveman Bob plays through a base game where spins can connect with world-specific wild symbol mechanics, random feature triggers, Mammoth Respins, Hand of Bob and Bob’s Wheel.

There is no scatter symbol or traditional free spins round. Instead, the slot uses standalone features that can interrupt regular play, apply symbol changes, add wilds, award wheel prizes or create oversized mammoth symbols. These systems sit alongside the game’s fixed payline structure.

Win Rules & Symbols

Caveman Bob is played on 5 reels, 3 rows and 20 fixed paylines. Winning combinations are formed by landing matching symbols on active paylines, starting from the leftmost reel and reading from left to right.

The higher-paying symbols include:

• Bob


• The mammoth


• Rhino


• Wolf


• Bird

Symbols

Wild Symbols

Wild symbols can substitute for regular paying symbols to help form winning combinations. Their exact behaviour depends on the active world, with wild reels in the Cave world, spreading wilds in the Oasis world and random blizzard wilds in the Mountain world.

Caveman Bob Bonus Features

Caveman Bob uses several random features instead of a single traditional bonus round. The main features are Bob’s Wheel, Hand of Bob and Mammoth Respins.

Cave World Wild Feature

In the Cave world, stalactites can turn reels into wild reels.

Oasis World Wild Feature

In the Oasis world, wilds can spread across the reels.

Mountain World Wild Feature

In the Mountain world, a blizzard can add random wilds to the reels.

Bob’s Wheel

Bob’s Wheel is a random prize-wheel feature. When triggered in the base game, the wheel can award an instant prize.

Hand of Bob

Hand of Bob is a symbol-upgrade feature. It can transform lower-paying symbols into higher-paying symbols, with the aim of creating or improving a winning combination on the reels.

Mammoth Respins

Mammoth Respins are based around mammoth symbols. When the feature is active, mammoth symbols can become larger symbols on the grid.

Caveman Bob Slot Summary

Caveman Bob is structured around fixed paylines, three game worlds and several random features. The slot does not use a traditional free spins round, so most of its variation comes from world-specific wilds, symbol upgrades, wheel prizes and mammoth-based respins.

Maths Profile

The game has 96.49% RTP, medium overall volatility and a 500x maximum win. Its three world format adds some variation, as the Cave, Oasis and Mountain settings each use a different wild mechanic and risk profile.

Structure Comparison

Caveman Bob sits apart from many Relax Gaming slots because it uses a three world structure rather than one central bonus format. Compared with later Relax Gaming releases that often focus on high volatility bonus rounds, multipliers or larger maximum wins, Caveman Bob is built around fixed paylines, moderate top wins and separate random modifiers. Its structure is closer to a feature led video slot than a hold-and-respin, Megaways or cluster based format.
