What is the Percentages theme?
The Percentages theme uses equations with proportional relationships. These are the kinds of calculations you'd do when working out percentages: dividing by common factors, multiplying by ratios, scaling numbers up or down.
Nerdle doesn't have a % symbol, but these equations involve percentage-style arithmetic. Think 80/4=20, 15*4=60, or 36/9+4=8. Unlimited play, 8-column grid.
