Chock a BlockIn Chock A Block, players build colorful apartment blocks bursting with life. On your turn, place one of two double sided block cards in hand into your apartment building. Make a block of four or more spaces of the same color at lease one of which has a "For Rent" sign and you can take a neighbor on display and add it to the block. Neighbors don't have a color, but they have a pair of features, some combination of cats, flowers, birds, and underwear.
