About us

ePuzzle lets you play and create swap puzzles online — solo or with friends.

Swap Puzzle is a fun twist on classic jigsaw games: instead of fitting pieces together, you swap two tiles at a time to complete the image. Choose from thousands of puzzles or make your own using any photo. Challenge yourself or join multiplayer games to solve puzzles together. All content must be appropriate — any offensive or unlawful images will be removed.
