Puzzle 1
River Logall logic puzzles
One fine morning, twelve intrepid travellers found themselves facing a rather large river that they had to cross.
Luckily, there was a log that they could use to cross the river, but only if they crossed in single file.
Can you figure out who crossed first (and the order in which they all crossed)?
Since they crossed from left to right, the first person to cross is on the right, and the last person to cross is on the left.
The names of the travellers were: Alex, Ashley, Billie, Chris, Jessie, Emery, Logan, Quinn, Riley, Ray, Sam, Taylor.
Sam got on the log three people later than Chris, which means that there were two people between them. Chris got on two people after Logan.
Ray got on the log two people earlier than Emery, who got on two people earlier than Logan, who got on three people earlier than Riley. Ray was not the first one on the log.
Alex got on the log two people after Quinn.
Billie got on three people before Quinn.
Jessie got on the log two people before Taylor. Jessie was not the first one on the log.
Taylor got on just after Emery.
