Tabletop Mahjong Solitaire (You don’t even want to see the actual URL.)
is where you’ll find our related spreadsheet.

https://vitamahjong.io/vita-mahjong-2025/ is designed for Seniors, who apparently prefer Casual Play (Umm, Really??). Aesthetically it’s a superior product. Technically, not so much.

Vita Mahjong uses a “Combo Box” which allows you to select up to 4 tiles. If the 4th tile does not match the 1st, 2nd, or 3rd tile, the game fails. This approach allows you to select a “pretty” tile, and then see if you can dig out its partner. The GotCha is that the only way to clear a tile, once you’ve selected it, is to dig out its partner.

Higgs Studios produces several Matching Games. Their version of Mahjong Solitaire is, technically, by far the best of the bunch. Aesthetically, not so much. They have a huge variety of puzzles (emphasis on PUZZLES) that offer well designed HAZARDS that will keep you on your toes.

There’s nothing casual about the Higgs Studios product, they don’t even offer an UnDo, which is appropriate as there’s nothing local about their hazards. Restart is a DoOver for the entire puzzle, with a different paint job, but the Tile RELATIONSHIPS are hard-wired for each puzzle, Higgs rarely (perhaps never) stacks tiles directly on top of each other, preferring rather to use Layers with a wild assortment of MULTIPLE staggers and offsets in each Layer. Their model provides excellent layering visibility, and you’re going to need it.

is the Unicode representation for Mahjong Tiles. We’ll be using it as our anchor point for the multitude of Mahjong Icons, which will hopefully allow you to avoid some of the confusion.
