About Quasi Puzzle
Quasi Puzzle is a faithful digital recreation of a classic circle-packing puzzle — a set of thirteen rounded, interlocking pieces that must be packed flat into a frame. It's a puzzle with no picture and no single answer: the same pieces can be arranged correctly in more than a thousand different ways, which is what keeps it interesting long after the first solve.
We built it because puzzles like this deserve to be preserved and played, not left to gather dust in a drawer. The digital version keeps the original mechanic exactly and adds a few things a physical set can't — unlimited hints, a picture mode, colour skins, a solutions gallery and an optional leaderboard. You can read more about the puzzle's history and the mathematics behind it, or jump straight in and play.
