You select the number you wish to submit as a guess, by adding or subtracting to the Number in the center of the screen. You accomplish this by using the buttons on the left side of the screen. 1 Adds, and -1 subtracts.
To wager, you press either the 5 or 1 button on the right side of the screen.
If you want, you can "buy in" for a '1st Guess Bonus', by pressing the Bonus button before you 'Guess'. If you don't have the 30 in the bank it takes for the bonus, you cannot buy in.
Press Guess.
Continue to Guess, until you get the number.
Your winnings are calculated as follow: Max number of guesses are 6. The Multiplier is equal to the Max Guess of 6. For each guess, the Multiplier goes down by 1. The payout is equal to your wager * Multiplier. That total is then multiplied by the number of Dice in play.
Press Re-roll, and the gameboard resets!
Have Fun!
