I like the way IYT has their tournaments set up by several sections, the winner(s) of each section goes on to round two and plays the winners of round 1, etc. until one final winner is left. IYT starts 2 tourneys a week for all kinds of games. I play Halma 10 on IYT. The invitations to the Ts are at the top of the window page and are very easy to follow, unlike the Ts on this site. I would play in such Halma 10, and Halma 16 for 4 players.
