We are waiting for correct answers! Great puzzle! The answer is trigger the pistol right away . Because you know the previous shot was empty, there are only 4 possible positions possible. The chance to hit the bullet is thus 1 in 4. If you spin again, there are 2 out of 6 killing shots, or 1 in 3 to hit a bullet. 1 in 4 is better odds than 1 in 3 to eat a bullet, thus you shoot the pistol right away without spinning.

That is correct answer! Seems that we need to come with something more trickier next time! =)

Great job! That is correct answer! Seems that we need to come with something more trickier next time! =) Thanks! I love these type of mathematical and logics puzzles. They really challenge you and in this case also provide you a bit of insight in the odds for winning (or surviving ) this gambling game. I hope you can come up with another challenging puzzle to put me up to a bit of extra thinking!

I hope you can come up with another challenging puzzle to put me up to a bit of extra thinking! Ok, here is another challenge for you. Imagine that you and your opponent start with 1 bullet loaded into the 6 slot. Both you and him will have to shoot without spinning and after shot pass the pistol to another. The question is do you prefer to start as first, or shoot in second turn?

I'd say that I would prefer to start first, as if I start, I'd have a 1 in 6 chance of taking the shot, while if I go second, I'd have a 1 in 5 chance of biting a bullet. 1 in 6 are better odds, so I'd like to start first.

You must consider, that if he misses his second shot, then the pistol will be in your hands again!

Ah, but it's a matter of probability. You have a 1/6, then 1/4, then 1/2 chance to shoot yourself if you go first. For your opponent, it's a 1/5, then 1/3, and then 100% chance of shooting themselves. Round 1: You have an 83.333% chance of survival Round 2: Your opponent has an 80% chance of survival. Round 3: The chances of you surviving both round 1 and round 3 (on average) is 62.5% or 15/24 Round 4: The chances of them surviving both round 2 and 4 (on average) is 53.333% or 8/15 Round 5: The chances of you surviving all rounds 1, 3, and 5 is 31.25% or 5/16 Round 6: Your opponent loses, guaranteed. You always have a better chance of survival going first.
I didn't put in the isolated case percentages because that's obvious. (And gambler's fallacy doesn't apply to this case, since future CAN be anticipated if you look at the rounds)

I will keep the secret a bit longer so others can participate too in solving the puzzle

Hint: The problem is in how you calculate odds
Ah. My bad. You want to go second. I hadn't miscalculated necessarily, but it was in isolated cases. Here's the revised edition: Round 1: P1 has a 1/6 chance of dying Round 2: has a 5/6 chance of occurring, P2 has a 1/5 chance of dying, which equates to a 1/6 chance of dying. Round 3: has a 4/6 chance of occurring, P1 has a 1/4 chance of dying, which equates to a 1/6 chance of dying. Round 4, 5, and 6 follow the same format. Looks like I screwed up! And you want to be second, since though the odds are the same, P1 COULD shoot themselves on the first round. Though if you average it out it doesn't really matter. Either works.
Alternate solution: go first and shoot your opponent.

A 1 in 3 chance of losing those that make it provably fair or the opposite ?

Would it not be a pure 50/50 chance (ie. "fair") regardless of where you started?
There are an even number of chambers and 2 players, so each player will have 3 chambers that they could potentially use. Regardless of who goes first, each player has an equal number of chambers assigned to them, so after the spin, both players have an equal chance of having a bullet in one of their chambers.
And because you can't change which chambers you have (no spinning) the odds of getting a bullet overall don't change from 50/50.
