A puzzle library consisting of dozens of antique puzzle box games. Each game in the library is rated according to difficulty levels. Every game is an adaptation of an existing physical puzzle box game. Many of the games are solved by sliding blocks to move from the starting position to the target position. Instructions on how to play are provided for each puzzle game. None of the games in this library are considered easy. Solving the puzzles requires careful thought. Currently, there are 54 puzzle games in the app. This number will increase in future versions. If we list the games included in the app and the dates they were produced:
