Ten Pennies Puzzle

Don't have pennies? You can print your own from the included 3mf file!

This is my own version of the game. I've found too many versions of this that are too easy to stumble upon a solution just by sliding the pennies around.

The spot that holds the 10th penny allows for the penny to be tilted for easy pickup (see photos). The puzzle requires no force to get all ten pennies inside the square.

***PLEASE DO NOT POST SOLUTIONS IN YOUR MAKES***

I have two versions:

• The first version should work for everyone, as it is designed with average tolerances in mind. 
• The second version was designed for printers with tighter tolerances. This makes the puzzle difficult to “accidentally” solve. There is no wiggle-room for 9 of the 10 pennies once it is solved.

Of course, feel free to scale either of these to fit your printer's tolerances if neither of these works for you.
