BUNCO description

There are six rounds, progressing in order from one to six, where the number of the round serves as the target for that round's rolls.

Within a round, players alternate turns rolling three dice, aiming to obtain the target number. Players gain one point for each dice matching the target.

If the player gets three of a kind of the target number, he declares a Bunco and gets 21 points. The round stops when a player obtains 21 points. Whoever wins the most rounds is the overall winner.

This is a version with two players: you and your device.
