I used to play on a site called CSGOReaper, which was a site for betting items from games that had value, before i knew about crypto, you would deposit skins to site, get a balance, and play with it.
There were sites with dice games, hence i found crypto gambling.
But the 2 things i have not seen in the crypto world yet is a "Jackpot" game and a "coinflip" game.
The coinflip game is where 2 players compete, one starts a game by choosing a bet amount and selecting High or Low (Low = 1-5000 high = 5001-9999). This bet then gets added to a list, another player, if he chooses to can join the game by adding the same value to the pot then a 10 second counter is started, at the end of the timer a number is rolled, and a winner is picked. The winner wins 95-99% of the pot, and the rest goes to DD.
Jackpot is where a group of players compete, there is an empty pot, when 2 people add fuds to the pot, a timer is started, there is no limit to the amount of players joining the game, but a limit to the amount of deposits to the pot, each player is allowed to add to the pot twice, and a total of 20-50 deposits are allowed per round.
When the timer runs out, people get numbers assigned to them based on when and how much their deposits were added and worth. for instance if the first player so happened to deposit 10% of the total pot value, he would get numbers 1-1000, if the second player happened to put in 5% of the pot, he then gets 1001-1500, so on and so forth.
This allos people to "snipe" the high or low numbers by either trying to deposit first or last, or somewhere in the middle.
when the timer runs out the numbers are assigned to players, a number is rolled, and whoever "owns" that number for the round wins 95-99% of the pot, DD keeps the rest.
This allows people with a 0.5% chance win the entire pot if they are so lucky and same with people having 99% chance, they could still lose.
But there is no risk to DD and DD doesnt pay them out for wins, DD merely takes the 1-5% commission from the round.
