How to play

Each wagon carries the completed blocks of one Sepolia settlement batch.
Send every whole wagon to a tunnel, oldest wagon first.
Blocks past a tunnel’s capacity are overflow. Your score is the total, and lower is better.
Try to finish inside a minute. The clock is for fun and never changes your score.
