Mahjong: Soviet Trio

Tiles carry familiar images from a Soviet childhood: a roly-poly doll, matryoshka, Sputnik satellite, pioneer scarf, brass samovar, spinning top and balalaika.

The rule is simple: tap a tile and it moves to the tray below. Three matching objects there burn away. The tray holds seven — fill it with no match to make and the level restarts.

Inside: • a thousand levels, from three-object warm-ups to deep layered piles • a daily puzzle with its own reward • helpers: return a tile, a hint, and clear three from the tray • a daily streak and a star meter • one-handed play, portrait orientation

No timer breathing down your neck: think as long as you like, moves never expire.
