Procedure

This game is played by two players. The players secretly enter a number in a chosen range, say 100 - 999. They then take turns asking for a digit. If one of the opponent's digits is guessed the opponent must state the value of the digit. eg:

Suppose Player A has 145 on the screen and Player B asks:

Please may I have a 4?

Player A must answer:

Yes, you may have 4 tens.

At this point Player A would have to subtract 40 from his/her total and Player B would have to add 40 to his/hers.

If a player does not have the digit requested, they answer:

Sorry I don't have one.

If a player has more than one of the digits requested, they may give any one without revealing that they have others.

Play continues like this until one player either reaches a calculator screen above 999 and wins, or below 100 and loses.
