Mahjong Earth

Mahjong Earth is a "Rotational-Spatial" puzzle game. The technical core involves "3D-Object Manipulation." Unlike flat boards, tiles are arranged in a 3D structure (cube, globe, pyramid) that floats in space. You must "Rotate the Model" (X/Y Axis) to find matching tiles hidden on the back or sides. It tests "Spatial Reasoning" and object permanence, as you must remember where a tile was after spinning the globe.

You see a 3D cluster of tiles. Your goal is to clear it. Interaction involves "Swipe-to-Rotate" and "Tap-to-Match." Rules are looser than solitaire: usually, any tile with two adjacent free sides (or simply "visible and unblocked") is playable. You must spin the structure constantly to reveal matches. Gravity often applies—clearing inner tiles might cause outer tiles to collapse inward.

Solving 3D structures depends on "Axis-Rotation Memory." Don't spin wildly. Clear one "Face" of the structure at a time. A pro strategy is "Core-Boring"—if the structure is solid, try to tunnel through the center. This exposes the "Internal Layers" which are usually the hardest to match because they are occluded from most viewing angles. Use the "High-Contrast" setting if available to distinguish tile edges in 3D space.
