First of all, thanks for bringing bet platform to the forum. Since matches with possible draw are not allowed then the gmaea are already program in such a way that it is not possible if not one day players would have drawn and once players would have drawn, how will you do to pay the players, that was what I was thinking, since you don't allow that it's even the best.
If I may suggest the certification Oracle code should be asked only the winner of the game not the loser. It is a nice game but OP if you are the owner of the platform you to work on the site and if you are not the owner and a representative in the forum, tell the owner of the project to work on the site and you the ANN thread manager should also work on the ANN thread.
Yes, you are right it is better to create an independent subject in ANN thread I will make it and publish the link here.
Yes, draw matches is not allowed for now. Only matches where 100% the winner will be known at the end of the match. But in case if something happened the majority would choose who is the winner. I mean everything is on chain and the results of certification Oracle would unlock the losers fund for winners side.
This is an example of fact certification OracleAs you can see the question is pretty simple: "Who won the WCUP 2022?". After the end of vote counting period it automatically unlock losers fund for winners.
