Caveman Bob review

The Caveman Bob game is developed by Relax Gaming. Although the slot machine was released in 2019, it remains interesting and relevant even today: the game is characterized by 3D graphics and a number of bonus features.

The video slot machine’s playing field consists of 3 rows of 5 symbols. The number of paylines is always fixed – 20 – and a winning combination can be formed on each of them. The game has an above-average RTP of 96.49% and volatility ranging from low to medium to high. Players can expect a maximum payout of 500 bets.

Gameplay and symbols

The Caveman Bob slot machine takes you on a journey back to ancient times, when the ancestors of modern humans roamed the Earth. The slot symbols are prehistoric mammals and stylized playing card values. The graphics are of quite high quality, featuring animations and 3D effects.

The online slot machine accepts bets from $0.20 to $100 per spin. Since the number of paylines cannot be changed, the player activates the reels immediately after selecting their bet amount. Fifteen symbols appear on the screen. To win, the user must collect 3 to 5 identical symbols on the same payline, starting with the leftmost reel.

In the Caveman Bob game, the payout depends on the bet, the type, and the number of symbols in the combination. The table shows the highest payouts for different symbols.

Features and bonuses

The Caveman Bob slot machine has one key feature: the game’s volatility can be low, medium, or high. Volatility depends on one of the three worlds in which the game is played. These worlds are activated randomly, but the player must play in one of them for a certain amount of time to unlock the next. The game worlds are:

  • Cave – low volatility. Stalactites land on random reels and transform into Wilds.
  • Oasis – medium volatility. Loose up to 13 Spreading Wilds.
  • Mountain – high volatility. 3 to 5 random Wilds appear.

The Caveman Bob game features three winning features that are activated during a random spin. Names and characteristics of these bonuses:

  • Hand of Bob. The symbol with the lowest multiplier is selected on the screen and promoted to the next level. If this does not form a winning combination, the process is repeated until the player receives a payout.
  • Mammoth Re-Spin. The mammoth symbol can occupy up to 4×4 cells, according to the current world.
  • Bob’s Wheel. The user can spin the Wheel of Fortune with a maximum win of 50 bets.

The slot’s Auto Play function allows you to configure the automatic reel rotation mode. The maximum number of spins is 1,000, and there are also conditions for stopping them prematurely.

Conclusion

Caveman Bob is a fairly interesting and functional slot machine with 3D graphics. First of all, you should pay attention to this slot because of the presence of three game worlds: Cave, Oasis, and Mountain. Activating each world grants a specific bonus. Furthermore, during random spins, three different bonus games can be triggered.
