This is a childrens version of the game Code Sudoku by Kod Kod International Games. This version uses two sided tiles with numbers with a corresponding colour and shape on one side or cute little pictures on the other. Puzzles range in difficulty with 4 x 4 grids of pictures at their simplest and 6 x 6 grids (unusual but it works) with numbers for the older / more experienced players. The puzzle sheet being attempted is placed into a plastic frame with a clear plastic cover over the top. The cover has a raised grid to hold tiles directly above the squares of the puzzle sheet. score tacks for 4 players run along the side of each puzzle sheet for competitive play in which each correctly placed tile earns a point.

Rules are in English but the game is language independent.
