Primate King Slot Bonus Features
Red Tiger is extremely fond of progression-based achievements, and Primate King is no different. To the right-hand side of the screen, players will see a metre with three levels. During spins, symbols will show up with gold coins attached – these coins will then be added to the metre. Once you have collected 30 coins, you will unlock the first upgrade – which turns the standard Wild symbol into an expanding wild covering 1x4 on the reels.
A further 30 coins will unlock the second upgrade, which sees a random multiplier added to the Wilds. Finally, once you hit 90 coins and fill the metre, the Wild will then become sticky, and the multiplier will increase. The Wild symbol will stick on the reels after a non-winning spin and stay there until you manage to land a win. Needless to say, this is an effective system for getting you to stick around and keep playing.
Once you have managed to unlock all three of the Wild upgrades, they will remain in place for the rest of the game. The bonus metre will then convert into a sixth reel on the slot, increasing your chances of a big win.
The slot also wants to keep you engaged when you aren’t winning or adding to the metre. The game has the Primate Smash feature, which can be triggered at random after a Wild lands as part of a non-winning combination. When this happens, the Primate King himself will come and remove all low-paying symbols and fill your reels with higher-paying ones until you secure a win.
