With 180 win lines, Mental is a highly volatile slot from NoLimit City with a 3-2-3-2-3 layout, and it plays out on a 3-2-3-2-3 layout. There are Fire Frames symbol splits, Dead Patient symbol multipliers up to x9,999, Enhancer Cells with six modifiers, Mental Transform and three bonus rounds. You can win up to 66,666x your bet.
Fire Frames are found in the base game, and they split symbols in half so that flames surround the reels 1 to 13.
This feature is triggered when 2 Dead Patient symbols land on the reels. One of them becomes a premium patient symbol with a multiplier of 5, 10, 15, 30, 50, 100, 300, 500, 1,000 or 9,999. Symbols count as win multipliers, so this is not a standard multiplier. There are Enhancer Cells at the bottom of reels 2 and 4, and these activate by 4 or 6 Fire Frames, respectively. Each Enhancer Cell awards one of six modifiers once triggered.
The Mental Transform feature triggers when you land spider symbols on reels 2 or 4. These symbols transform into an xSplit, xWays, Wild, Dead Patient or Patient premium symbol.
If you land three Scorpion scatter symbols on reels 1, 3 and 5, and each scatter lands in a Fire Frame, you will win 8 Autopsy Free Spins.
It is really hard to comprehend everything that goes on when this slot game is firing on all cylinders (or even 50%, for that matter). In terms of complexity, convoluted and disturbing themes, Mental is undoubtedly the most challenging such release. There is an excellent visual presentation, but it is horrific at the same time. Furthermore, there is an eerie soundtrack that will make your skin crawl.
However, if you walk away after cashing in some big wins, then the creepy stuff will soon be forgotten about.
