About This Game

PuzzleBox is a SUPER addictive number puzzle about compounding: drag a number block onto another block with the same number, merge them into double, and challenge yourself to keep the chain alive. The rule is one sentence; the strategy is a habit of reading the whole box before touching anything. Merges cascade when new doubles form next to their twins, so the board rewards players who set up two merges with one placement. Minimal presentation, maximum loop satisfaction. If you enjoy number games that respect your logic, PuzzleBox earns its capital letters. Free in your browser, instantly.

How to Play

Drag a numbered block onto an identical numbered block to merge them into double the value. The game ends when no block on the board has an identical twin to merge with. Plan two merges per placement: the merge you make and the merge it enables. Tip: leave your two largest blocks apart from the crowd — a high-value pair placed together is your only path back into a crowded board.
