Monster Slider (Japan) — About this game
Monster Slider (Japan) makes the slope of the puzzle field part of its matching system. Blocks slide from the higher side toward the lower side, so their resting positions depend on more than where they first arrive. Reversing the incline changes that movement and can rearrange the groups already on the board. Planning a useful reversal therefore means considering both the next piece and the blocks that will slide after it, rather than treating the pile as a fixed stack.
