Ripple

Ripple is a timing-meets-logic puzzle game set in a luminous underwater world. Tap cells on a hexagonal grid to emit expanding wave pulses that toggle cells between lit and dark on each rhythmic beat — plan both where and when to tap so that all target cells glow simultaneously. Master wave interference across 90 hand-crafted levels spanning six worlds, each introducing a new mechanic: walls that block, amplifiers that re-emit, mirrors that reflect, currents that bend, and frequency locks that filter by color. Featuring a seeded Daily Challenge, a freeform Meditation mode, procedural audio that reacts to every ripple, and full keyboard and screen reader accessibility — all in under 25 KB.
