We can deposit to escrow like 0.1 each and at the end of day we solve ourselves and tell escrow

Thought so to avoid house edge !

moreover I don't know any sportsbook that offer odds on things like how many fours in next over ( cricket )

anyways thanks, I will lock this soon

To avoid scam : deposit to escrow before playing by both players.

To avoid hack : Every bet will be signed ( bitcoin signed mesage )

then whats the problem ?
