How to Play The Monsterinos Slot

Let’s learn all about these little monsters and how to play the Monsterinos slot!

First, you need to adjust the stake that you want to wager per spin. From the menu below the “Spin” button, select the bet options and choose the number of paylines from just a single payline to as many as 25 paylines. 

After selecting the paylines, choose how much to bet. The minimum wager is just $0.01, but the maximum bet can be as high as $25 per spin.

“Auto-Play” is available if you want to take more of a passive role. Just set the total number of spins and the wager and the reels will turn on their own.

The paytable can be found in the same menu as the betting options, allowing you to have a look at all the payouts and features.
