Mahjong Pyramid is the classic tile-matching game played on a stepped pyramid. Four layers shrink towards a single tile at the top, and only tiles with a free left or right edge can be taken. Clear the whole pyramid against the clock.
Mahjong Pyramid builds the 144 tiles into a stepped pyramid. Work from the top down, freeing lower tiles as the apex clears.
Four layers of 64, 36, 16 and 4 tiles — 120 in total, so 60 pairs to clear.
Because it is boxed in. A tile also needs a free left or right edge, meaning at least one of its horizontal neighbours must already be gone.
The board is reshuffled automatically so that a pair always remains available.
It is more compact and easier to scan, but the middle can seal up, so it rewards careful ordering.
