PrimeXTime vs Number March

Kill some time and give your brain a little exercise at the same time with this simple game. You start with a random number and then start dividing by single-digit primes (2, 3, 5 or 7). When you can't do any more divisions you 'bump' the number -- multiplying by 10 and adding any single digit. You win the game by reducing the original number to 1.

Numbers are marching across your notebook — and only math can stop them! Number March is a unique tower defense game where your weapons are division. Place towers along the path to divide marching numbers down to 1 before they escape. Start simple with small composites, then face increasingly tricky numbers as primes enter the mix. HOW TO PLAY • Numbers march from start to finish along a winding path • Tap to place towers anywhere on the grid • Towers automatically divide passing numbers by their value • Tap a tower again to increase its power • Reduce every number to 1 before it escapes, or you lose points • Keep your score high to earn up to 3 stars per level 60 HAND-CRAFTED LEVELS Work your way through 60 carefully designed levels, each with a unique maze layout and number sequence. Early levels teach you the basics — what towers do, how division works, and how to plan ahead. Later levels throw bigger composites, faster spawns, and tricky primes at you. THINK FAST, THINK SMART As you progress, numbers get larger and march faster. You'll need to think about prime factorization, tower placement strategy, and when to upgrade versus when to build new. Every level is a fresh puzzle. NOTEBOOK PAPER CHARM Everything is drawn in a hand-sketched style on notebook paper — wobbly lines, pencil textures, and a warm classroom feel. The upbeat soundtrack keeps things fun as the challenge ramps up.
