Advices and Tips to Play Mental

1. Try Out Demo Mode on Bonus Tiime

It gives any player an opportunity to discover the game mechanics and its special features for themselves. In this way, before a single cent is bet, a player can be familiar with Mental‘s scatters and wild cards – and how these have an impact on the overall game. This leads us to the next pre-game tip for canny players: take a look at the pay table.

2. Relax and Entertain Yourself

Trying first the free slot demo is the perfect way to unwind, relax, and simply enjoy playing Mental – without losing money or the stress to catch chasing wins.

Combined with spending a little time in demo mode, this preparation will allow players to place their first bet with confidence when beginning the proper game.

4. Plan a Betting Budget and Stick to it

Anybody concerned with promoting Responsible Gambling will offer one piece of advice first and foremost: don’t bet more than you are prepared to lose. When it comes to play online slots for real money, then this manifests itself through sticking to a pre-agreed budget. If a player reaches their betting ceiling without a big win then it is time to call it a day. Stop playing as soon as you reach the budget limit.

5. Don’t Be Dazzled by Huge Jackpots

Some expert gamblers spend their time online chasing those mega-jackpots. While there is nothing wrong with that, it is a fact that slots offering huge progressive jackpots normally have higher odds and less chance of paying out.
