You start as Red against an 'intelligent robot'.
Click the shaker to throw the dice. Six dice will appear.

If you are happy with your throw (values see below), click the PASS button, otherwise you can throw several dice back into the shaker (just click them) and throw them again.
You have to leave at least one dice with value (a '5', a '1' or a triple) outside.
Once you have decided to keep a dice, you cannot throw it back into the tumbler later.
If in any throw you do not come up with any valuable dice, you lose all points of your turn! So think carefully when you want to stop and make all your points count.
To stop, click your PASS button.

Special case:
If all of your dice count you have another round of play (click the PASS button). This may happen a few times in a row.

Scoring:
'1' : worth 100 points,
'5' : worth 50 points
'2', '3', '4', '6' : worth nothing as single dice.
Three dice all showing '2': 200 points,
Similarly, triples of 3, 4, 5, 6 are worth 300, 400, 500, and 600 points.
Three dice all showing '1': 1000 points.
Please note that triples only count when thrown in one go!

The value of the dice which are fixed (i.e. the dice you have already decided to keep) is shown in the upper number of the display. Your current combined score of all previous rounds is shown in the number below.

If a player gets 5000 points or more, its opponent still has another turn so that he/she has a chance to catch up. Hence the first player with 5000 points does not necessarily win.

This solitair game has been derived from the Zillions two-player game 'Fivethousand', which did not supply the computer opponent with any intelligence. That is why I designed a separate game where you can play against a more sophisticated program. (The Zillions system does not give a programmer the information whether a player in a 2-player game is a computer or not).

Fivethousand is a traditional dice game played with six dice. In the original game, you may still loose all your points in a bonus round. In this Zillions game, this rule has not been implemented for technical reasons. If you fail in a bonus round, you still keep all points you gained in the first round.
