On your turn, click ROLL to roll the dice. If you rolled some scoring dice, take some points and add them to the bank. Then, decide whether to bank your points or roll again.

You need 300 or more points before you bank. Banking the points adds the points in the bank to your score and ends your turn. If you roll again instead, and you don't roll any scoring dice, you Zilch, lose all of your points in the bank, and lose your turn! And if you Zilch three times in a row, you lose 500 points! The first player to 10,000 points wins!

Here are some tips: You need to decide when to bank your points, and when to keep rolling. If you have only one die left to roll, there is a 2/3 chance you will Zilch, but if you roll a 1 or a 5, you will get to roll all 6 dice again! Also, you can decide not to take all of your points when you roll - it's sometimes a good strategy. Lastly, check to see if you've earned a free roll. Always take your free rolls, as you get to roll all 6 again!
