the piranha, and panics half the time. The Nurse always panics, but half the time she is calmed down, and half the time she jumps (alone) out of the boat and must swim ashore. When the boat capsizes, everybody must swim. Dead people always float to the correct shore, and incredibly, the canoe gets there too.

When swimming the events that follow may occur to each person in the water, individually:

Dead people always float ashore
Live people make it ashore unscathed half the time. The other half, they aquire minor wounds (probabilty 0.67) or major wounds (probabilty 0.33). In no case do they come out of the river healthier than they went in. (Note, these probabilities could be made worse the further there is to swim.)

On shore the victims health may become worse with the following probability: Healthy people never get worse.
Attended people get worse with a probability of 0.11.
Unattended people get worse with a probability of 0.33.
Dead people never get worse.
To get worse means that a minor wound becomes a major wound or a person with a major wound dies.
When a minor attended wound gets worse, it become a major unattended wound.
The ‘Worse Health’ events should be computed for each person once per canoe trip, whether or not the person participated in the latest trip. So people who were wounded early in the game have more chance of getting worse that people wounded later.

Scoring:

 1000 starting maximum points -100 for each dead person -30 for each major unattended wound -15 for each major attended wound -10 for each minor unattended wound -5 for each minor attended wound

Certain programmers with particularly warped minds might like to modify the program for a ‘Maximum carnage game’ (minimum score). To do this you need a new rule: On each successive trip you must leave at least one more person on the shore than the previous round trip.

Happy paddling.
