BlockU

BlockU is a calm, elegant logic puzzle. Place polyomino blocks onto a grid so the number of filled cells in each row and column matches the targets shown on the edges. Sounds simple - until the targets demand specific colors, blocking cells split your space, and the only way through is rotating that one awkward Z-piece. ✨ FEATURES • 31 hand-crafted levels across four difficulties — Tutorial, Easy, Medium, Hard • Endless Mode — infinite procedurally generated puzzles in four difficulties (Easy → Expert) • 19 polyomino shapes from monominoes to heptominoes • 5 color themes with their own icons — snowflake, crystal, blossom, flame, leaf • Smart hints — 5 free per level, or watch a short ad for more • Tap to rotate placed blocks • Star rating per level based on hint usage • Dark mode and color-blind mode • Sound and haptic toggles, optional level timer • Multi-language: English, German, Spanish, French, Italian, Portuguese, Russian, Turkish, Indonesian, Vietnamese, Japanese, Korean, Simplified Chinese • Offline play — full game works without an internet connection • No accounts, no registration, no daily streaks 🎮 HOW TO PLAY 1.

Every level has a designed solution but most have several valid paths to it. No timers, no penalties, no pressure. The aesthetic is intentionally calm: soft pastels, rounded corners, glass-morphism UI. No flashing lights, no shouting menus, no "limited offer" popups. 🆓 FREE TO PLAY BlockU is free, supported by occasional non-intrusive ads. The optional Remove Ads purchase removes interstitials. ——— Made with care by Shinguru Games. Privacy: https://omer-metin.github.io/shinguru-games-legal/privacy-policy.html
