Rectsmith: Area Race

Rectsmith is a calm rectangle puzzle. Every number is a rectangle: drag from it to the opposite corner so the area equals the number, then cover the whole board. One tidy solution, every time.

• Solo — unlimited boards, free on 8×8 and 10×10, three clue densities.
• Daily board — everyone gets the same board; keep your streak (one complete per day).
• Race a friend — same board, dealt by the server. First valid full partition wins. Share a link, QR, or five-character code. No account for either of you.
• Rematch — never interrupted by an ad.

Free forever on 8×8 and 10×10. Optional Extra Boards unlocks 6×6 and 12×12. Optional Remove Ads turns off the between-round ad. An occasional interstitial appears only when you leave a finished Solo or Daily board for Home — never mid-race, never on rematch, never on a win celebration.

On-device stats only. No account. No leaderboards.
