Shikaku: Flow Mosaic

A new challenge every day: three puzzles, a streak with rewards and palettes you unlock by showing up.

Shikaku is a puzzle you can hear. Every move answers with a note, a soft click and a light haptic tap, and melody levels play Ode to Joy or a lullaby as you solve them.

The rule is simple: divide the grid into rectangles so that each holds one number — equal to its area. Every solve turns into a glowing pattern.

SOUND AND MUSIC • A response to every move: sound and haptics • 5 sound moods: twilight, lo-fi, synthwave, choir, chiptune • Melody levels: lullabies, classical masterpieces, world melodies

LEVELS LIKE NOWHERE ELSE • Shaped boards: a cat, a heart, a house, a star, a butterfly and more • From a 5×5 warm-up to a 40×40 giant

300 COMBOS • 6 designs: contour, glass, paper, gradient, neon, spectrum • Palettes for every design, dark and light appearance

SOMETHING NEW EVERY DAY • Daily challenge: quick, regular and the shape of the day • Your streak unlocks palettes and sounds and brings sparks • The shop: new shapes every day
