In order to place a bet in Thimbles, you need to use the interface of the gaming machine. You can determine the size of the bet by pressing the left or right arrow buttons located at the bottom of the screen. A little further there are buttons that switch the game level: to 2.88 or 1.44. After setting the parameters, the containers are mixed automatically. The player only needs to choose the one where the pebble (or two) is hidden and get his winnings.
