Two Ways To Play: Sprint: take on a 10-question run against the clock.
Survival: keep going as the time allowed for each question gets shorter.
Find Your Challenge: Practice all four operations at Warm-up, Focused, or Challenge difficulty. Choose a comfortable starting point or push yourself with tougher numbers.
Chase Your Best: Earn bonuses for quick answers and consecutive correct answers. Track your best scores for each operation, mode, and difficulty, then review your answers after each run. Three hearts give you room to recover, and mistakes reveal the correct answer.
