Roulette and casino chips
Where the roulette table is, how betting works, every chip and the lottery tickets.
the roulette table
The roulette table is at Lenny's Motel, where you also find the Smuggler, the Suspicious Door and an ATM. Buy chips at the table, put them on numbers or sectors, and wait for the wheel. The closer your bet, the more it pays. When you win, swap the chips back for cash at the same table.
Other players bet on the same spin and you see their bets on the table. Each spin has a betting window, then "All bets set" and the wheel goes. There is a limit on how much you can stake, and the game tells you when you hit it.
The payout for each kind of bet is worked out on the game's servers, so it is not in the files and we will not guess at it.
the chips
Chips are items that sit in your bag, one slot per stack of 100. At face value a full stack of Chips ($100K) is $10,000,000, so carry them like cash: as a Criminal you lose them if you go down.
lottery tickets
A Lottery Ticket comes from the battle pass. Scratch it and the server rolls what it turns into. Each result is its own item and sells to the Fence for exactly its face value.
