Following the rules, use a pen or pencil to write the appropriate numbers in the
boxes until it is filled. When choosing a number for a corner piece or
edge cell, you must write the number in the adjacent cell on the adjacent
face(s). See diagram below.
Like Sudoku, the rows and columns and square regions on each face must contain a
series of numbers without repeating.
The example shown is of a 4x4 cube, however the same rules apply to a 9x9 cube as well and are similar to how all Sudoku games are played. The ZudoCube difference is that common edges and corners must share the same
number turning the 6 faces into one giant puzzle!
A special coating on the cubes makes it easier to write and erase pencil marks
so any pencil will work, but for the ultimate experience get ZudoPencil.
ZudoPencil combines a high quality mechanical pencil with lead of the perfect
thickness and softness making it a must have for all gamers.
