## What is BLK?

BLK is a merge puzzle about fading to black. Swipe to slide every tile on the board. Matching colors merge into the next color down the fade — white softens to sun, sun deepens to amber, and on down through coral, violet, and dusk toward pure black.

Make a black tile and the light is out.

No numbers. No timers. No noise. Just color, and a soundscape that blooms with every move — soft bells that echo and drift, sinking lower the deeper you fade. Pick a sound palette to match your mood, or shape your own.

FEATURES
• The fade: WHITE › SUN › AMBER › CORAL › MAGENTA › VIOLET › BLUE › DEEP › DUSK › ASH › BLACK
• Reaching black is as hard as making 2048 — then keep going and fill the board with darkness
• Four levels, from chill 6×6 ZEN to brutal 4×4 HARD, each with its own high score
• Ambient generative sound — every swipe, merge, and tap is a note in the space
• Sound palettes: Glass, Bloom, Night, Deep, Interstellar — or build your own with the custom sliders
• Gentle haptics that bloom under your fingers
• Light and dark themes
• One-handed play, works offline, no accounts
• Completely ad-free with no in-app purchases

Easy to learn, endless to sink into. How dark can you go?
