Each value is represented by a different form.



Three levels of difficulty are proposed:

- easy: a cell can be empty or have value 1 (circle)

- medium: a cell can be empty or have value 1 (circle) or 3 (triangle)

- difficult: a cell can be empty or have value 3 (triangle), 4 (square) or 5 (pentagon)



During a round it is initially proposed a grid having only one form to find, then two, up to number of cases. In case of error it is necessary to start again the same level (same number of forms to be found). Each grid proposed is chosen by chance but has always only one solution.
