Pietjesbak is a simple and competitive game played with 3 dice which are traditionally thrown in a wooden octogonal box from which the game gets its Flemish name.
The variant played here is called 69 (sixty-nine) and is played as follows :
You are playing against iPhone and by turn have to throw the 3 dice inside the frame a maximum of three times. 
Each player gets at the start 9 strokes. 
The initial start order is decided by (system) coin-toss .
The first to play can chose between 1, 2 or 3 throws. The best throw counts. 
The number of times the first player throws will determine the number of times the next player is allowed to throw. 
You throw the dice by shaking the device.
The best throw at each turn will result in erasing one or more strokes for the winner of the turn.
