BLK: Color Merge Puzzle

BLK is a calm colour merge puzzle about fading every tile to black.

Swipe to slide the board. Matching colours merge into the next shade down the gradient: white softens to sun, sun deepens to amber, then coral, violet and dusk until you reach pure black. Make a black tile and the light is out.

The logic is easy to learn and as challenging as reaching 2048, but there are no numbers, timers or noise. Just colour, a minimal board and an ambient soundscape that blooms with every move.
