Roll of the die (Posted on 2005-04-21) Difficulty: 4 of 5
The object of the dice game is to be the first player to reach a score of at least 100 points.
Each player’s turn consists of repeatedly rolling a die.
After each roll, the player has two choices: roll again, or stop.
- If the player rolls 1, nothing is scored in that turn and it becomes the opponent’s turn.
- If the player rolls a number other than 1, the number is added to the player’s turn total and the player’s turn continues.
- If the player stops, the turn total (the sum of the rolls during the turn), is added to the player’s score, and it becomes the opponent’s turn.

What's your strategy?

Hints/Tips Nearly there | Comment 16 of 23 |

You guys have developped a nice and correct theory for the start of the game and have indeed found out that the strategy should change as a function of yours and the opponents score.  Nice work.
The total solution is probably  not something for this web site, more for a highly specialised math web site.  But there is one thing I should like to see:
A general idea of when/how you will change your strategy and start taking risks.

One remark: several comments mentionned that you should  take very large risks if the opponent is at 99.  Then my question is: Why would the opponent stop at 99?
