The toughest Solitary Sixty challenge yet offers the biggest reward - it's time to make a STRAIT-ESCAPE!
Nicolas is secured inside the straitjacket. His ankles are chained to the cell floor. The key to release them dangles just behind his head. If only he could reach it!
His Solitary Sixty begins at the same time as his bid for freedom.
To escape, he must first free himself from the straitjacket before unlocking the ankle cuffs.
The prize for escaping starts at an incredible £1,500.
But for every second that passes, £10 is taken off the prize fund.
If the prize pot reaches zero, his attempt has failed (and that takes 2 minutes and 30 seconds, to save you doing the maths).
The guard chains the straitjacket to the top of the cell and locks him behind the cell door for the remainder of the hour!
