Tuesday Handshake Puzzle Solution: 6

 

Displaying this puzzle in a square format allows for a visual solution.

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

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

Seán will have already shaken hands with Amy and Liam so he 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.
