The Handshake Puzzle- solution

Answer: 6 handshakes

Displaying this puzzle in a square format allows for a visual solution. In this case we are demonstrating the relations between four people.


We can see that Amy (in the red jumper) will have a total of 3 handshakes: one with Liam, one with Samira and one with Luke.

Liam has already shaken hands with Amy so he will have two more handshakes: one with Samira and one with Luke.

Samira will have already shaken hands with Amy and Liam so she will only have one more handshake with Luke.

Luke, at this stage, will have shaken hands with everyone in the group.

There will be a total of six handshakes for four people.

Amy, Liam, Samira and Luke meet up. Each person shakes hands with every other person once.
