EDIT2; Ronnie, what happens when one of us are going through here? Will the winner of me and athreekv get both the last clouds or will we get a chance to predict a lonely game to get the highest cloud (and if so,
what happens with the other cloud?). If it's the first and whoever goes through gets the 0.27
BTC this is a huge fight for the both of us as loser would get "only" 0.079
BTC 
May I answer instead of Ronnie? In the post with rules it is said:
- Any prizes left unclaimed after 6 weeks from competition end will be forfeit. 
As I understand, you will go futher untill one of you loses on prediction. Now you are competing for 0.079BTC. If it will be a draw, you will split the prize and the competition will be finished. I guess, with all the left prizes Ronnie will make some kind of a raffle, as the funds are already marked as "expenses" in the Cloudbet budget

Cloudbet already used some kind of that with Cloudbet's Super 6 Soccer Predictor Competition. In the end some unclaimed free spins were raffled between participants.
