PerPuzzle 1.21

PerPuzzle is an app created for Mac that gives you access to four types of puzzle challenges, each with its own board style. The game features an integrated help guide that teaches you how to complete each puzzle and handle the app's functions properly.

You can select the preferred game style from the app's toolbar. The app lets you play Fifteen, Sixteen, Orbit, and WrapSlide puzzles. Your objective is to arrange all tiles in a certain order. For instance, the Fifteen puzzles can be solved by arranging all tiles in ascending order (from 1 to 15). The games can be played by using your mouse.

At first, the app displays the correct order of the tiles which need to be rearranged. After you click the Scramble button you can start moving the tiles based on the initial board display. Furthermore, you have access to Reset and Auto Solve options which come in handy if you're unsure how to complete the puzzles.

My only issue with this app is the fact that it lacks an option to save your gameplay progress.

However, PerPuzzle is perfect for a break from work. Plus, it's free of charge.
