Harder Russian Roulette (Posted on 2004-09-11)

A six-shooter is loaded with three cartridges in consecutive chambers, before two persons start to play "Russian Roulette" until one is dead.

If the cylinder isn't spun after each attempt, would you rather be the first shooter, or the second?

What would be your answer if there are only TWO cartridges, of course in consecutive chambers?

Solution: (Hide)

In both cases, it's better to go second. In the first case, the first player will die if he gets one of the three cartridges, or the middle empty chamber. In the other case, he will die if he gets one of the two cartridges, or the first or third empty chambers after the full ones.
