Games here are always open as long as you have no intentions to scam users here
. Its better if you use escrow in your turtle fight
. Kidding.
Just put your game on the Games and Rounds section and make many advertisements inside and outside the forum so that many will be aware in your game. Good luck.
I guess I laugh after seeing your joke about turtle fight but I guess making our own gambling game in this forum is not prohibited as long as you would put it in the right thread section there is no need to worry about it, however animal fighting or underground fighting event (that is for humans) I guess that will make a stir and it is prohibited in the forum in my opinion because it is really against the law and the forum will not tolerate something as cruel as that,
And about OP's idea of a turtle race, I guess that is one brilliant idea to start up something in the forum that is gambling and betting with our cryptocurrency, And because of that I have come up with a great idea in the future on what can I do to simply past time and getting something in return because of it.
