Kurushi Final: Mental Blocks (also known as I.Q. Final) is a challenging 3D puzzle game for the PlayStation. Players are placed on a floating platform and must use spatial awareness and quick thinking to clear waves of advancing cubes before being pushed off the edge.
How to Play
The objective is to clear normal and green “advantage” cubes while avoiding the black “forbidden” cubes. You mark a square on the grid and “sink” it when a cube rolls over it. Sinking a green cube creates a 3×3 trap zone to capture multiple cubes at once, while sinking a black cube penalizes you by destroying a row of the platform behind you. By default, PlayStation controls in the browser are mapped to your keyboard: use the Arrow Keys to move, and Z, X, A, S for the action buttons (to mark and sink cubes), with Enter as Start.
Tips
- Master the Green Cubes: Setting up 3×3 chain reactions with the green advantage cubes is essential for surviving later stages without getting overwhelmed.
- Watch the Black Cubes: Sometimes it’s better to let a wave of cubes pass than to accidentally sink a forbidden black cube and lose precious platform space.
- Adjust the Speed: If you’re finding the puzzles too difficult or too slow, you can adjust the speed of the advancing cubes in the game’s options.
