PATTERNO is a game of observation and focus.

You play with a deck of cards. Each card has 4 characteristics (Color, Shape, Pattern, Number), and each characteristic has 3 variations.

Your challenge is to pickup combinations of 3 cards, with the following constraints:
for each characteristics, the 3 cards have:

- all the same variations (3 Blue cards, 3 Triangles, …)
- or all different variations (Blue + Red + Green, …)

Will you find all the combinations?
