Three free runs a day. How far can you climb before the clock beats you? Pure addition, endless levels and a global leaderboard. Add the numbers. Tap the answer. Beat the clock. Number Sprint: Addition is one skill and nothing else. It starts with sums anyone can do and gets harder the better you are. Three misses and the run is over. Two ways to play: - Free run. Start at level 1 and climb. Every five right answers brings bigger numbers, a shorter clock, and wrong answers that sit closer to the right one. It never ends, and your best score goes on the global leaderboard. - Pick a level. Choose one of nine kinds of sum and stay on it, from single digits to three two-digit numbers. Also inside: - Streak multiplier. Five right in a row doubles your points, up to five times. - Quick to play. A run takes a minute or two. Play three runs a day for free. A one-off purchase unlocks unlimited play and removes the two-minute limit on free plays in Pick a level. No ads, no subscription, and the game collects no personal data.
