About & Contact
Puzzle Lounge is a site of free puzzle games: Sudoku (Nanpure), Jigsaw puzzles, Minesweeper, Tangram, Nonogram, the Loop Puzzle, Pentomino and Color Link. It is made and run by one independent developer in Japan.
Who makes it
NagiLab plans, designs, builds and runs the whole site alone. Puzzles are fun to think through on your own and fun to solve with someone else, and I wanted one easy place to do both. New games and improvements keep coming, guided by what players tell me.
What we care about
- Play the moment it opens, with no sign-up or install
- Thinking, not luck (Minesweeper deals only boards with no forced guesses)
- Fun alone, or with friends in co-op and head-to-head
The games
The jigsaw pictures
The masterpieces are public-domain images published by museums such as The Metropolitan Museum of Art, the Cleveland Museum of Art and the Rijksmuseum, each linked to its museum's page. Some pictures were drawn for this game.
How the site is funded
By ads and optional paid plans (Lounge Pass and Ad-free). A paid plan never gives an advantage in rankings or matches.
