Mahjong Dimensions turns mahjong solitaire into a three-dimensional puzzle. Spin the tower, find matching pairs along the open edges, and clear every tile before the clock catches you.
Mahjong Dimensions is mahjong solitaire rebuilt in three dimensions. Instead of a flat layout you get a tower of tiles stacked in shrinking layers. You can spin it with your finger or mouse, which turns a static puzzle into something closer to holding a real object.
In flat mahjong solitaire, a tile is free when nothing rests on top of it and its left or right side is clear. Dimensions keeps that rule but applies it in depth: a tile high in the tower is only reachable once the tiles above it are gone, and tiles in the middle of a layer stay locked until you open a path from the edge.
Spin slowly. At a shallow angle the tower looks solid; at roughly forty degrees each layer separates visually and the free tiles stand out. The strongest habit is to clear the outside ring of a layer first — it unlocks everything inside it.
The flat version trains pattern spotting. The 3D version adds spatial planning: you are not just choosing a pair, you are deciding which part of the stack to dismantle first, because the order you clear tiles in decides which ones become reachable next.
A tile is free when nothing sits on top of it and at least one of its left or right sides is open. Spin the tower and the free tiles are the ones with a clear face.
The game detects the deadlock and reshuffles the remaining tiles automatically, so a round never gets stuck.
It uses the same matching rule, but the layout is a rotating tower instead of a flat board, which adds depth and rewards planning ahead.
