Klumen

Filaments of light lie scattered and twisted apart. Tap a tile to turn it, and join every filament to its neighbour until light flows from the heart-star through the whole weave — and it wakes. Hundreds of always-solvable puzzles that grow with you: obstacles, portals, one-way valves, linked gears, and prisms that mix two colours into a third. The music is made by the game as you play — slow notes that fade, never a loop.

Tap or click a tile to rotate it. Join every filament to its neighbour until the light flows from the star in the centre through the whole board. One thumb, no account, nothing to install.
