In 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. You'll find these features in other rooms, too, and if you make a chain of 6/8/10 of the same feature, claim a matching scoring token. As soon as everyone has finished a 4x3 building, count your points from scoring tokens and unscored chains of at least four features. Challenge the vicious "AutoBlock" mode as a solo player if you love puzzles.
