Features of the Mental Slot

The game is played on five reels of different sizes. Reels 1, 3, and 5 contain three symbols each. Reels 2 and 4 have only two symbols, along with separate windows for modifiers that activate during gameplay. The main symbols are divided into two types. The highest-paying symbols depict patients, while the lower-value symbols represent human organs. There are a total of 20 winning paylines. The maximum possible multiplier is 66,666x the bet. Bets range from 0.2 to 70 currency units. The volatility is stated as extremely high, and the base game RTP is 96.08%. When purchasing bonus rounds, the return rate slightly increases.

The game features several unique mechanics that activate under specific conditions on the reels:

1. Burning Frames – These split the symbol inside them into two parts.

2. Transformation – Spiders landing on reels 2 and 4 transform into other symbols.

3. Duplication – A symbol can replicate into adjacent positions on the slot.

Mental Bonus Game

There are three bonus rounds. The basic round is triggered when three scorpion scatter symbols land on the reels. These only appear on the larger reels. The round consists of eight spins, during which up to five burning frames appear randomly on the reels. The number of spins increases with the appearance of additional scorpions.

The second-level bonus round activates if, along with three scorpions, one spider lands on the reels. This round follows the same rules as the standard bonus game, but the reel containing the spider will activate the transformation function on every spin. The third-level game starts if, in addition to three scorpions, two spiders appear. In this round, two reels will have the permanent transformation function.
