TRIANGLES :

Players buy 3 and 4 spaces triangles from the 36 spaces triangle of the board. In that order, they bid simultaneously and secretly for a pair of triangles on the board. When the bids are revealed, the winner of the auction marks the two acquired spaces with triangles of his colour, and gets points of reward. He then elects two new spaces on the board for sale.
Every three rounds, all players receive 100 extra points for bidding.
The Board has special areas showing the capital and scores of each player.
