Use the sling puck game to find the code.

Make sure each puck with a colored sticker is placed and lined up where the corresponding colored sticker is.

If pucks are in the correct positions, 1 on the left should lead to 7 on the right, 2 on the left should lead to 2 on the right, and 3 on the left should lead to 3 on the right. The code is 723
