The Rules of Oonsoo =================== Although the idea of Oonsoo is quite similar to the idea of Spider, it may be a bit confusing in the beginning, since in Oonsoo, you have to stack cards of the same rank. Oonsoo is played with 48 cards, giving 12 piles of 4 cards each to build. You may only move cards of suit club to empty spaces. The suits in descending order are Clubs, Spades, Hearts, Diamonds. You may only move cards of lower suit onto higher ones, thus the six of hearts may be placed upon the six of clubs and on the six of spades, but on no other card.
