We all know the general rules in sudoku… Things are a little different here. Each 2x4 block, each vertical row, and each horizontal row must contain the numbers 1-8 Here’s where things get tricky, you must imagine that you are looking at a 3-dimensional figure. You are viewing 3 sides of a cube. As such, horizontal and vertical rows twist around the cube. On the blank version of the puzzle for example, the 4 2 7 and 3 on the left are part of a 2x4 grid defined by bold lines, the 8 4 7 form a vertical group as do the 5 7 and 6. The 4 2 5 and 3 are an example of a horizontal group. The actual cache container/hide technique should be obvious upon approach.

Good luck.
