Color Sudoku: Shapes & Music

Sudoku with colors, shapes and music instead of numbers. Every color plays its own note, so each move you make becomes part of a melody. Start on a tiny 4x4, step up to 6x6, then master the classic 9x9.

HOW IT WORKS • Fill the grid so every row, column and box holds each color once. Pure logic, no math. • Each color has its own shape: heart, star, leaf, drop, circle, diamond, triangle, flower and square. Easy to read, and friendly for colorblind players. • Each color is a xylophone note from a pentatonic scale, so whatever order you play, it sounds good. Complete a row, column or box and hear a chord.

A LONG JOURNEY • 200 levels across 10 worlds. Each world starts a little below the last one's peak and climbs higher: challenging, never crushing. • Learn the rules on 4x4, speed up on 6x6, then take on the full 9x9. Later worlds introduce new solving techniques. • Every puzzle has exactly one solution and can be solved with logic alone, no guessing.

BONUS LEVELS • Three bonus levels in every world: open the Treasure chest for coins and a hint, hear your board play its own song in Melody, and beat the target time in Lightning to multiply your reward. • Bonuses are optional and pay three times the coins. World finales bring big rewards too.

HELP WHEN YOU NEED IT • Smart hints point to the next logical move and explain why it works. • Notes mode lets you pencil in small color dots; matching notes clear themselves when you place a color. • Undo, plus a color lock for fast painting.

A REASON TO COME BACK • Collect a daily gift and keep your 7-day streak going. • Earn stars on every level and try to finish them all with three. • Turn stars into titles, from Color Apprentice to Color Legend.

COMFORTABLE FOR EVERYONE • Big, easy-to-tap cells and a calm, clean look. • Satisfying sounds and haptics, both easy to switch off. • Display options: shapes and colors, colors only, or colors with numbers. • Works offline. Plays on iPhone and iPad. No account or sign-up needed.

Pick a color, place a shape and let the melody guide you.
