About Solvarium

Solvarium is a small collection of logic puzzle games. Each one takes a single classic puzzle, most of them first printed in the Japanese puzzle magazine Nikoli, and turns it into a full game with a campaign, a daily puzzle and endless boards.

Behind it is SEQUENCODE, a one-person studio in Germany. A computer generates the boards and a solver checks each one. If a board has more than one solution, it doesn't make it into the game. The same solver sits behind the hint button, which is why a hint can tell you why a step is right.

Every game is free to play here in your browser. Some of them are also on Google Play for Android, where they work without a connection too.
