About
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 every size (6×6, 8×8, 10×10, 12×12), three clue densities.
• Blueprints — four curated collections by size (Warm-up, Classic, Expert, Marathon). Open any sheet; track your progress.
• 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.
Every board size is free forever. Optional Remove Ads turns off ads for good (once, forever). Already bought Extra Boards? Thank you — you've been upgraded to ad-free at no cost.
An occasional interstitial appears only at calm moments: when you leave a game for Home, or when you open a Blueprints size collection — never mid-board, never mid-race, never on rematch, never on a win. Optional short video can unlock the largest board (12×12) for the current session; free sizes and racing never require it.
On-device stats only. No account. No leaderboards.
Rectsmith is original Queuegames software inspired by the public-domain rectangle-partition family (Shikaku). It is not affiliated with LinkedIn or any “Patches” product.
