Casinos do have a color coding scheme for their chips. The main thing to recollect is that while most casinos follow an identical color scheme, they don’t accept one anther’s chips. One armed bandits will also take US denominations of bills to play. Nickel and quarter machines will also take US coins to play. You can only get change at the cages and booths. A secret that most people are not aware of is you can can place money on the table if it is purely for 1 or 2 fast gambles. As an example, at a $2 21 table, you can place 2 buck on the table for the minimum bet on each hand. You cannot do it for long, but you should be in a position to play 2 or 3 hands. So if you’re on your way out the door, you can still make an impulse bet.
