Rectify — the number rectangle puzzle

How it works

Drag out a rectangle over the board. It clears when its area equals the sum of the numbers inside it.

Here, a 3 × 2 rectangle has an area of 6 — and the tiles inside read 3 + 2 + 1 = 6. It clears.

Swipe instead, and every tile slides 2048-style toward that edge. New tiles spawn after each move. Play until the board locks up.

Two puzzles in one Shikaku-style rectangle logic fused with 2048 sliding. Every move either scores or reshuffles the board.
Special tiles Bombs, freezes, chains, lightning balls, splitters and multipliers turn a tidy board into a combo chain.
Endless score chase No timer and no fail state until the board is truly locked. Game Center leaderboards and achievements.
Themes worth unlocking Dozens of hand-tuned themes earned through play, each with its own particles and palette.
Built to be readable Colour-blind-safe and high-contrast themes, reduce-motion support, and full Dynamic Type.
