Currently Skrilla features contests in League of Legends, CS:GO and DOTA 2. All of these contests do not have the possibility of resulting in a draw. These are the rules of the current eSports that we feature on our website and aren’t determined by Skrilla. The only case where a match will end in a draw is if the match is cancelled for some reason halfway through the match. In that case you will get refunded your stake as the match didn't reach completion.
This alternatively provides better odds for you! With only two outcomes being possible as opposed to three, gives more reason to test your skills, participate and win!
