Goosebumps-giving gameplay of Mental slot


The chilling visuals and theme set to make you jump

With games like Mental, it is sure that Nolimit City knows how to think out of the box, and we must say, they went really crazy with this one. In the past, we have seen games based on prisons and graveyards from this studio, but this time they did a truly impressive job, even to their standards.

You might feel that Mental is a torture chamber rather than an online slot, and we won't blame you. The various graphic elements like the background, the animations, the symbols, and the reels are all set strictly according to the theme.

The scary soundtrack also syncs in smoothly with the ominous visuals, and you get well-designed gameplay. The whole game is set in a mental asylum, which is quite apparent from the sepia-tinged walls and the flickering lights, along with the bleak colour scheme.

When the San Quentin video slot was released sometime earlier, another scary-themed title by the same developer, it caused quite a controversy. Mental is designed in an even crazier manner, and you should get ready for a pretty electric and sinister gambling experience.

The symbols in Mental are also designed to give you goosebumps and chills. You get picture symbols including hearts, lungs, brains, skeleton hands, and eyes. Some mentally-disturbed patients will also appear on the reels, which are marked from 1 to 5.

The skull denotes the wild symbol, and the spider is the scatter symbol.
