The game will initially present a screen for choosing 7 numbers between 1 and 49. Then, 20 hidden pieces will be presented to be revealed in the way and the way the player decides. At the end of the revelation of the 20 pieces, the panned value will be presented. If such panned value matches one of the 7 chosen numbers or pans a number greater than 49, the player wins a bonus. If you pan a multiple of 9 between 54 and 135 the player gets a special bonus. By panning the number 144, the highest possible value per turn, the player gets the super bonus.
All moves will be recorded and computed, generating a history of the total mined, greater and lesser mining (negative number) and bonuses earned.
