The Eleventh Episode. Each game had a time limit of two, two-and-a-half, or three minutes. If the contestant failed to exit the chamber within this time limit, before the timer hit zero, they would be 'locked in.' Additionally in a minority of games, known as 'automatic lock-in' games, the contestant could also be locked in by committing a foul, for example by touching the floor if this was forbidden for that game, or by setting off an 'alarm' three times. If the contestant breached the penalty rules in an 'automatic lock-in' game, they would be locked in straight away, irrespective of whether or not they had obtained the crystal, and regardless of how much time they had left. Contestants who were 'locked in' were unable to play further, unless the team captain chose to buy a contestant's freedom at the cost of a previously earned crystal, which could be done at any time after the lock-in.
