On October 28, Chancellor John Healey is scheduled to present the autumn budget to Parliament. This annual event requires the government to navigate a complex set of competing financial priorities, including funding public services, maintaining acceptable tax rates for the electorate, and ensuring that bond market creditors remain confident in the government's ability to manage its debt.

To illustrate these challenges, The Guardian has published an interactive game that invites readers to act as the chancellor. The simulation tasks players with designing a budget that satisfies political stakeholders, such as backbenchers, while simultaneously managing the expectations of financial markets and maintaining a balanced ledger. The game serves as an educational tool to highlight the practical difficulties inherent in fiscal policy, emphasizing the trade-offs required when allocating national resources. While the exercise is designed to mimic real-world constraints, it remains a simplified representation of the actual budgetary process that will be formally unveiled by the government later this month.
