The Professor's Balls
There exists in the professor's mind a remarkable billiards game. It consists of any number of balls, but only three colours: red, green and blue.
There's one player.
Each round the player chooses a ball and takes a shot. If two balls collide and they're different colours, they both turn to the third colour.
However, if two balls collide and they’re the same colour, nothing changes.
Occasionally the player may also find that they can play a trick shot by allowing three balls to collide simultaneously. When that happens, and they're of different colours, all three change to one colour at the player’s choice. If two of the balls are one colour and the third is a different colour, nothing happens and the player takes the next shot.
However if three balls collide and the balls consists of only two colours, then the two balls that are the same colour change to third colour.
You are challenged by the professor to a wager. There are 13 red, 15 green and 17 yellow balls on the table. He will give you £100 if you can turn all of the balls into one colour; if you can’t, you must give him £100.

others forehead, and can never look at their own. Anyone who breaks that taboo will be killed instantly by the others.
Although they have small fishing boats, they don't have the means to leave for another island, and have understandably becoming rather irritated with each other.
However, there is hope. There is a prophesy amongst the islanders that a boat will come which is big enough to take them all off the island forever. Never to make things easy for themselves, however, the prophesy also says that only those with circles on their foreheads can go. Those with triangles must stay. If anyone with a tr…
