About This Demo

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 fight using 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 actions, 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.

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. 11 draws cards.

Take 66, for example:

66 → 2 × 3 × 11

Trigger multiple effects at once from a single number.

The goal isn't simply to make the biggest number possible.

It's figuring out how to pack the effects you need into a single number.

Watch the enemy's next move, study your hand, and create the number you need for that turn.

This isn't a game about finding the right answer.
It's about creating your own.

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 change forms, altering the way numbers themselves can be combined.

Even with the same cards, a different form can lead to completely different numbers—and completely different strategies.

Which form will you use?
Which cards will you take?
And what will you create from the hand you're dealt?

Every run brings a new answer.

In the demo, you can challenge the entire first stage and its boss.

The demo lets you play from the beginning of the full game through the first stage and its boss.

Use 3 different forms.
All cards are available.
Your save data carries over to the full game.

Continue your deck and progress directly in the full version when it releases.

Some Laboratory features are limited in the demo.

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 thinking this way to win battles.

But as you play, the primes hidden inside each number start revealing themselves naturally.

And even after you close the game, you may catch yourself factoring the numbers you see in everyday life.

Try the demo and see what numbers you can create.
