The Chancellor game from UK Fact Check
Red BoxChancellor Simulation
Run the nation's finances. Survive the consequences.
You've just won the election — and inherited the books. Set the Budget, face the bond markets, negotiate with the unions, survive the front pages, and try to keep the keys to No. 11.
Three ways to win
Survive longer than anyone else. Get out of No. 11 and into No. 10 faster than anyone else. Then last longest once you are there. They reward completely different games.
Fastest to No. 10 Lowest wins
Months served before the challenge that won the leadership. The only board where the smallest number wins.
Nobody has made the thirty-foot walk yet.
Longest-serving Prime Minister
Months at No. 10, counted from the day the keys changed hands.
Nobody has governed from No. 10 yet.
Best economy at five years
Growth, prices, jobs, debt and the country's mood, scored after exactly 60 months.

How scores work — honestly
Checked, and auditable
Scores are reported by the game and checked against server-side plausibility bounds. Every entry carries the run's seed and engine version, so the whole run can be audited and moderated.
One free account
Sign in inside the game with a 6-digit email code — the same free UK Fact Check account as the news app — to track your bests. The boards are strictly opt-in.
Private by default
You appear here only if you choose a public profile, under a display name you pick (never your email or username), with a generated cartoon portrait rather than a photo.

The keys to No. 10.
Built by UK Fact Check — the fact-checking project. The game teaches the real machinery: where the money comes from, where it goes, and why the Bank of England doesn't answer to the Chancellor.
