You can vote your coins towards red, blue or both. In general the color with the most votes wins. But there is a voting cap such as 60% or 70%. If a team goes beyond the cap, it is disqualified and the other team wins. A fixed number of coins are created by inflation at the end of each round. When the final block of the round is mined, the winner is determined and those coins are divided up and split among everyone who voted for the winning team.
There is also a rule that votes cast early in the round count more than votes cast late in the round. This is because people voting near the end of the round have more information about the likely outcome of the round, while early voters have less information and are therefore rewarded with more votes.
