⬣ ABOUT ⬣
First broadcast in 1982, Countdown is iconic British TV. Its numbers game is the perfect balance of challenge and simplicity. In this video, I analyse the hidden mathematics of the game: What are the hardest targets, best numbers to draw, and optimal tactics?
⬣ TIMESTAMPS ⬣
00:00 - Introduction

10:00 - Reachable Numbers from a Given Game Set
14:00 - Results and Tactics: Small Numbers
24:00 - Results and Tactics: Large Numbers
31:00 - Scary Numbers
40:05 - Outro
⬣ CHALLENGE ⬣
So to clarify, I want to see a list of the percentage of solvable games for ALL options of large numbers. Like I did for the 15 options of the form {n, n+25, n+50, n+75}, but for all of them. The options for large numbers should be four distinct numbers in the range from 11 to 100. As I said there are 2,555,190 such options so this will require a clever bit of code, but I think it’s possible! Email me via my website if you think you have it!

⬣ INVESTIGATORS ⬣
I’ve never seen that colour on my screen before. I’m hoping you excel yourself and slug out the solution. Now is the perfect time to join the investigation.
