Charlotte, Jamali and Sarah get out through the gate
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Charlotte, Jamali and Sarah struggled to work out the code, causing Charlotte to ask "What's the situation?", attempting to remember which stone set off the alarm. They eventually worked out that by saying the word 'red', they were able to get to the gate. They got to the gate in 15 minutes and 50 seconds and set off the alarm 34 times, receiving 0 points each.
