Games & Media / FACTORIZE: 1
Before you know it, you'll be factoring every number you see.
Build numbers. Unleash primes. Discover new strategies.
FACTORIZE: 1 is a turn-based deckbuilding roguelite where you combine cards to create numbers and battle with the powers of the prime factors hidden within them. Leave the prime factorization to the game—you just decide which number to make. Read the enemy's next move, figure out which prime effects you need, and build the right number from your hand. Even with the same cards, there's never just one answer.

Features
The number you make is your strategy
Every number you create is instantly broken down into its prime factors, triggering the effects of each prime within it. 2 attacks, 3 defends, 5 heals, 7 strikes multiple times, and 11 draws cards. Take 66: 2 × 3 × 11 lets you attack, defend, and add more cards to your next hand—all at once. The goal isn't simply to make the biggest number. It's figuring out how to pack the effects you need into a single number.
Change your deck, and the answer changes with it
Along the way, you'll acquire new number cards and refine their combinations to build a deck of your own. Your companion Fio can also transform into six different forms, and each form changes the way numbers can be combined—opening up entirely different strategies with the very same cards.
Before you know it, numbers start to look different
You see 12: 2 × 2 × 3. You see 35: 5 × 7. At first, you're only doing it to win battles. But as you play, the primes hidden inside each number start revealing themselves—and even after you close the game, you may catch yourself factoring the numbers you see in everyday life.
