Types & Variants

The tiles stay the same; almost everything else changes. At a table, Chinese, Hong Kong, Japanese riichi and American rules score differently enough to be separate games, and a player fluent in one can sit down to another and be lost by the third turn.

Online the split runs a different way: stacked solitaire, flat connect grids, rotating cubes, tall towers. These pieces map both families, explain what each one asks of you, and point to the section of the catalogue where that format lives.
