Whats Up is a fast card-flipping game in which you race to collect sets of birds first.
To set up, shuffle the thirty double-sided cards, then lay them out on the table in a grid. Each card features 1-3 birds in one of four colors — red, green, yellow, purple — with the reverse of the card having either the same number of birds in a different color or the same color of birds in a different number. Thus, each number+color combination appears five times in the deck.
