A card representing a combination of several colored dots is placed on the table.
Each user has 4 transparent plastic cards also with colored dots in different positions and has to superimpose them to obtain the same combination as the card on the table.
The difficulty is that you will have to hide dots of cards you placed below to obtain the right combination.
The first player to have the same combination shout "Vitrail" and if his combination is correct wins the card.
Box contains: 16 (4x4) transparent cards. 64 combination cards.
