Rings & Cones is one of A-O-A's line of "Big Games" - and it is big, with a 22"x22" board (large for an abstract) and plastic cones 3" across. The game is a twist on N-in-a-row games - players are trying to get 5 (in 2-player or team game) or 4 (with 3-4 players) things in a row, but the things can be either the large cones or the rings (in 4 sizes) that fit over them, so you have a 3-D N-in-a-row. In addition, pieces can be moved once placed.
