Xmas Mahjong Trio Solitaire

This one swaps mahjong's usual layered-tile-pairs setup for something closer to a stacking game: tiles pile up in horizontal rows of nine, and you're matching three of a kind rather than pairs to clear them out. Let the stacks overflow and the round ends, so there's real pressure to keep rows moving rather than hunting for the perfect match. The holiday skin — wreaths, ornaments, that kind of tile art — is mostly cosmetic, but it's a genuinely different structure from the mahjong solitaire most people expect.
