Summary of the rules:
- Start with a number in the 50s
- Roll the dice and decide whether to add or subtract that number of tens
- If you roll a 6, you might have to roll again as you might go off the end of the numberline
- The aim is to try to finish back on your starting number after 10 rolls of the dice
