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. - BoardGameGeek
