Block puzzle for iPhone

The block puzzle that plays fair.

Drop blocks on an 8×8 board, clear rows and columns, and chain them into big combos. Every tray of pieces can be placed, ads only play when you choose them, and you duel real players on the same pieces.

Our promise

Three rules we never break.

Every tray can be placed

Before a tray is dealt, Comboo checks every order of the three pieces. At least one order must fit them all, so you never get an impossible tray.

No forced ads

No banners and no ads between games. A short video plays only when you pick it, for example to revive. Skip it and keep playing.

Skill counts

Duel real players on the exact same pieces and climb a rating that never resets, from Bronze to Grandmaster.

Ways to play

Four modes, one fair deal.

Ranked Duel

Play the same pieces a real opponent near your rating already played, with their score running beside yours. Higher score wins. If no recorded game is close to your rating, you face a Practice Bot, always labeled as a bot.

Daily Board

One board a day with the same pieces for everyone. Your first attempt counts. Keep your streak and see where you rank.

Journey

Goal levels with gems, ice and obstacles. Each level reveals part of a mosaic picture, chapter by chapter.

Classic

The endless high-score chase. Chain clears turn after turn and the combo multiplier keeps growing.

Fair Play

How pieces are dealt.

These rules are also in the app, under Fair Play.

  • Never an impossible tray. A solver tries all six orders of the three pieces before you see them. If no order fits, the tray is never dealt.
  • Help only goes one way. Outside Duels and the Daily Board, if you're far below your usual score, shapes get slightly kinder. If you're beating your best, you get normal random shapes, never a trap.
  • Duels and the Daily Board are identical for everyone. They use pure seeded pieces with no adjustment, so every player gets exactly the same deal.
  • Scores are checked. Daily and Duel scores are verified by replaying your moves against the same pieces before they count.
