2 track boards are ideal for regular games, between two people. 2 tracks also work well for two teams of two. We also recommend 2 track boards for engagement and wedding gifts where the accent is on two people! 3 track boards add the option of an extra player in a three-hand game but also still works for four playing as pairs. It can make it more difficult to fit in the extra track on some layouts though.. 4 track boards are the most flexible of all, suitable for 2, 3, or 4 players, individually or in teams. If the track has curves, it can be very hard to bend them and still maintain good spacing on the insides of the curves. choosing between these options is largely a matter of personal preference, but is sometimes influenced by the board shape and track layout.
