The Overtime box is a multiple step box that is likely to challenge the best of puzzlers. The inspiration for the design came from the creator's nephew whose nickname is OT. It’s a good play on words as you may need quite a bit of overtime to solve this one… There is also a series II version which adds an extra pin and an extra bit of complexity. Both boxes feature the Phoenix artwork lasered into the top.
Note that no force at all is required to solve this. Fingertips and brainpower are all you need…
The box externally measures about 5.2 x 4.2 x 3.4 inches (not counting the dials which extend another .75 inches from one side. Internal space for inserting something is about 4 x 2.8 x 2.3 inches. The internal space has a felt lined bottom.
