Flashback #2 – 4x4x4 Minesweepers

Another inclusion to the set was this 4x4x4 Minesweepers. I first encountered it in OAPC 7, and Serkan Yurekli cited it as an invention from Ali Aldas.

Example

4x4x4 Minesweepers: Locate the positions of 16 mines that occupy empty squares. The numbered cells indicate how many mines surround that cell. No mines can appear in the same cell as another mine in another grid.
