How to play

Your streak is the score — how many you got right in a row before the run ended. Each board keeps the best run per name.

The sums get harder the longer your streak runs — from single digits up to carrying and two-digit tables. Pick one operation to drill it, or play them mixed. The wrong answers are the ones people really make, like the next row of the times table.
