Rect10: Quick Math Puzzle

The numbers are bubbles! Pop rectangles. Sum to 10. Clear the board.

Rect10 is a bright, cheerful arithmetic puzzle game designed for pure mental flow. Scan an organized grid of bubbly digits (1–9), drag a box around any rectangular region whose numbers add up to exactly 10, and release to pop them!

Whether you are popping a pair (7 + 3), a trio (5 + 3 + 2), or an expansive multi-cell cluster (1 + 2 + 3 + 4), any rectangular shape works. Popped bubbles dissolve away, allowing you to tunnel across empty sockets to unlock high-scoring combos!
