Gambling concept in my Roblox game against TOS?

I want to make a wild west/cowboy style game on Roblox. I want to add saloons around the map that act as a social area or hangout, almost like a little hub area for chilling.

I had an idea to add blackjack, poker tables, and slot machines as decoration and just for the atmosphere (unplayable gambling content); however, I had a new idea. This content WOULD be playable, but you wouldn’t actually lose anything or spend Robux/real-life currency on them.

Basically, using daily rewards or completing quests, you can get coins to spend on these machines. Next, you would play blackjack, poker, and the slot machines like normal and in return you can win in-game currency (cash). After winning, you can double or nothing and try to keep a streak to win even more money or you can leave early to take your winnings home.

I feel like this doesn’t go against Roblox TOS because these coins are NOT obtainable through spending in-game currency, Robux, or real life money; they are given out for free by playing the game and accepting daily rewards. You also never lose any in-game currency that you purchased, you only lose the opportunity to play another game if you don’t have any more coins to spend on the machines.

Would this be against Roblox TOS? If yes, how can I make it allowed so players can have another opportunity to make more in-game currency for free? Any extra cool ideas is also welcome. Thank you!
