You make 2 cuts at 1/7 and 3/7 of the bar. This gives you 1/7, 2/7 and 4/7 piece of the bar.
Day 1: Give 1/7 piece.
Day 2: Give 2/7 piece in return for 1/7 piece.
Day 3: Give 1/7 piece.
Day 4: Give 4/7 piece in return for 1/7 and 2/7 piece.
Day 5: Give 1/7 piece.
Day 6: Give 2/7 piece in return for 1/7 piece.
Day 7: Give 1/7 piece.

If the second shot goes empty, you will be spared by him. What will you choose?

Welcome to the deadly game placed by the serial killer Jigsaw. You are tied to a chair and you cant move your hands or get up. Jigsaw shows you an empty gun with all the six chambers empty. He puts two bullets in the adjacent chambers and then close the barrel. He spins it and then point the gun to your head. The first shot snaps. It was an empty slot.

Now before pressing the trigger again, he asks you whether to pull the trigger or to spin the barrel first and then pull the trigger.

If the second shot goes empty, you will be spared by him. What will you choose?

Also think what will you chose if the bullets are not in the adjacent chambers.
