Something like this, maybe it is it but i feel like they were just solid colored without symbols. Very maximalist and saturated in color too, probably oriented towards children or game addict adults. Might have been one of those included with Windows default games but I think it was probably a seperately installed thing, also possible but unlikely to be one of those CDroms from a cereal box lmao. No idea

(this is not CozyMahjong)

Currently playing CozyMahjong (they make other Cozy games) but I crave the totally solid mahjong tilez
