QuickDigits is a sixty-second math sprint. Pick which operations you want to drill — addition, subtraction, multiplication, division or a mix — choose a difficulty, and start. A problem shows up with four answer tiles; tap the right one and the next appears straight away, so the pace is entirely up to how fast you can think. A running streak multiplies your score, and a wrong tap costs you the streak and a couple of seconds, which keeps every answer honest. When the clock runs out you get your score against your saved best, and a Stats page keeps your accuracy, games played and longest streak over time. Short rounds, quick restarts, and a number that slowly climbs the more you practise.
