Tappzi

Tappzi is a fast arithmetic puzzle game. Every level deals you a grid of number tiles and a goal. Tap tiles to move your running total onto the goal exactly, in as few taps as you can, before the clock runs out. Thirteen worlds and 130 levels teach the game one idea at a time. First Numbers starts with tiles that add up to 20 on boards that cannot be lost, so anyone from first grade up can learn the loop. Then the numbers grow, the clock starts, the total stops starting at zero, tiles can be tapped twice, and subtraction arrives. The last three worlds add board rules: tiles that are off limits, tiles that freeze and thaw, and boards that slide while you play. The Daily Challenge deals one board a day, the same for everyone. Your first attempt counts and the rest is practice, and a streak counts the days you complete. Scoring rewards two things. Fewer taps earn stars and multiply your score; finishing faster raises it. Every level is replayable, always with a fresh board. No accounts, no sign-in, no ads and no purchases. Every level and the Daily Challenge are free, for good. Nothing you do leaves your device unless you choose to share it. Tappzi is for all ages: simple enough for a six-year-old to pick up, and still worth a grown-up's lunch break.
