About this game

Spectra is a swipe puzzle with no numbers on the board. Progress is colour: every merge moves a tile one step up the spectrum, from slate through blue, green, yellow, orange and red, to a glowing white tile — and, if you keep going, to a rainbow.

Swipe in any direction, watch the tiles slide and merge, and listen. Each merge in a cascade plays the next note of a rising pentatonic phrase, so a good move sounds as good as it looks.

MODES
• Classic — 4×4, no clock, the reference game
• Calm — 5×5, room to think
• Blitz — 3×3 against a 60-second timer
• Daily challenge — the same board for every player, changing at midnight UTC

KEEP YOUR STREAK
Play the Daily every day to build a streak. Miss one day a week and your streak survives; milestones at 3, 7, 14 and 30 days unlock new colour palettes for the board.

BUILT TO FEEL GOOD
• Springy tile motion, particle bursts on every merge, a glow around the white tile
• A rising musical phrase for cascades, an ambient bed you can switch off separately
• Haptic feedback tuned to what just happened
• Reduced-effects mode for older devices

Free to play. No account needed — start playing the moment you open it.
A 2048-style puzzle without numbers. Merge tiles and climb the colour spectrum.
