Lots of bidders. You take seat around the table , and some employes take your bids and put them in the several squares on the table. Each seat place has a correspondent square in the table.
You bid in a colour - for instance RED- there are 4 (?) holes with red colour and with numbers 1, 2, 3, 4. If the ball stays in red 4, for instance, and you have bidded on red you win 4 times the bid
Very comic. Also the ball ( billiard ball) is introduced in the holle in the " roulette", striking the ball with a cue stick.
Next message I will show a picture- you can see the seats
