{{output}} Sample game (TEST == true):

```
Number of players from 2 to 9 : 2

The number of coins in your hand will be randomly determined for
each round and displayed to you. However, when you press ENTER
it will be erased so that the other players, who should look
away until it's their turn, won't see it. When asked to guess
the total, the computer won't allow a 'bum guess'.
