A few years back, I caught about 15-20 episodes of "The Link," a BBC quiz from the mid-2010s hosted by the guy who played Ron Weasley's dad in the "Harry Potter" films (Mark Williams).
The bonus game was essentially the last incarnation of the SOTC bonus game on steroids. Per Wiki ...
The team has 60 seconds to identify the links between sets of items. One contestant plays at a time, and is shown one item at a time in a list of 10. The clock begins to run when the first item is revealed, and stops when either the contestant buzzes-in to guess the link or all 10 items have been revealed, whichever comes first. A correct response moves the team one step up a six-level money ladder, using the same values as Round 1, but a miss requires the same contestant to play a new list.
After any correct answer, the team may choose to stop the game and keep the money won to that point, or risk it and continue playing. If they continue, the partner of the contestant who played the last list takes control. Identifying six links in 60 seconds awards £2,000 plus the cash total brought in from Round 2. If time runs out, the team leaves with nothing.
I did not catch a single bonus win during my viewings. No team came close to having a stone's throw of winning the jackpot. It wouldn't surprise me if there were 1-2 bonus wins max in the 65 episodes aired.
