Why Burn Vote?
The second series of The Celebrity Traitors began on BBC One on 1 October 2026: 21 famous faces, a Highland castle, and up to £100,000 for their chosen charities. It airs on Thursday and Friday nights, with the final on Friday 30 October. The first celebrity series was the UK's most-watched show of 2025, peaking at 14.9 million viewers for the final.
This series has a mathematician at the table. Before going in, Hannah Fry said she had gone back through the data of all the previous games looking for “statistically significant patterns”, had “spreadsheets coming out of my eyeballs”, and would look out for burn votes — Traitors voting for someone unexpected early on — using the same kind of cryptanalysis Alan Turing used on Enigma. She also admitted: “Whether it's going to work or not, honestly, your guess is as good as mine.”
So: can maths actually catch a Traitor? Burn Vote is a game built to let you find out for yourself.
How the meter works
The meter is not a guess or a vibe score. It's an exact Bayesian posterior. In a 12-guest castle with 3 Traitors, there are 165 possible Traitor trios among the 11 guests who aren't you. The game lists every one of them that is still possible given what's been revealed (banished guests reveal their role, murdered guests were Faithful), and scores each trio by how well it explains every clue you've seen. A guest's percentage is the share of total weight held by trios that include them.
P(trio | clues) ∝ Π P(clue | trio)
P(guest is a Traitor) = Σ P(trio | clues) over trios containing the guest
The clues and the likelihood model the meter uses:
- Tells (when you Watch someone): shown by Traitors 50% of the time, Faithfuls 20%.
- Alibis: a Traitor's story cracks 45% of the time, a Faithful's 10%.
- Mission fumbles: Traitors 30%, Faithfuls 10%.
- Accusations and votes: a Traitor is very unlikely to name or vote for a partner (relative weight 0.1–0.15); a Faithful is somewhat likelier to land on a real Traitor (1.8×) than on anyone else.
- Burn votes: a vote nobody else matched comes from a Traitor 30% of the time, from a Faithful 15%.
- Murders: Traitors are three times likelier to murder someone who voted for or accused one of them at the last round table. So every murder whispers something about the people the victim was pointing at.
The castle's other guests use the very same engine, plus their own private clues and a personal “gut” bias — which is why they make mistakes, herd, and sometimes come for you. The Traitor bots ride the crowd, cast the occasional burn vote, and now and then throw a doomed partner under the bus.
The model is deliberately simple, and the real show is much messier: real Traitors adapt, recruit, and read the same patterns a mathematician does. In Burn Vote the number of Traitors is fixed and announced, and there's no recruitment, so the maths has a fair chance.
Modes
- Faithful: find every Traitor before they equal the Faithful in number.
- Traitor: murder by night, frame and charm by day. In Spreadsheet mode you see your “heat” — how suspicious the table's public evidence makes you look.
- Gut mode: the meter runs in secret. At the end you find out how often your votes agreed with it.
- Castle numbers: the same number always seats the same guests with the same hidden Traitors, so you can challenge a friend.
