LoShu

Lo Shu is a calm, satisfying number puzzle inspired by the ancient magic square of the River Luo. Place stones numbered 1 through 9 on a 3×3 board.

Plan ahead, save one stone in the eddy for later, and keep the turtle shell from filling up. Features: • Simple 3×3 puzzle play with surprising depth • Clear lines by making 15 • Hold one stone for the right moment • Endless runs and a Daily River challenge • Optional guide glow for possible clears • Scores, records, combos, sound, and haptics • An atmospheric ink-and-river visual style Every line is the same river.
