5 attacks, unlimited fortifies.
You may return to attack from fortify, but you may not return to place.
Each player begins with a capital city, either P, L, A, or Y. If you lose your letter, you lose the game. Each player also begins with a clown with 0 units in it. Each clown attacks to the lower section of the ballon above it's head, which attacks to the upper section of the balloon which can reach the opponents capital cities.
Independent from that, there is a 12x12 grid on which you can aquire bonuses, which allow you to place units in your clown and begin to pop the balloon. The edges of the map wrap around at the top and bottom, and the continents do as well. The continents consist of making chains. Each straight line of 5 territories, vertically or horizontally, are worth +2, and if you control a territory and those to adjacent on the top, bottom, right and left is +1.
The minimum bonus per turn is 0, and territory bonus is disabled. Cards increase by 1 from 5-20, then reset to 5; you may hold up to 5. Dice on the grid are 5v8, and dice from the clowns to the letters are 6v6. Balloons have 2 sections of 100 neutrals each.
