Steer a number down a grid of tiles from 1 to 16, dividing by factors and adding the rest, to finish on 1.
Factors Game is a bite-sized math puzzle. You get a single number and sixteen tiles, valued 1 through 16, laid out four by four. You guide your number down through the grid, one row per move. If it lands on a tile that divides it evenly, it gets divided. Land on any other tile and that tile’s value gets added instead. You earn the best grade by ending on 1.
The game has 256 levels, and each one hands you a starting number that matches its level. That means the arithmetic steadily gets trickier as you climb.
How a level works
Above the tiles, your number rides in a colored box. Shift it sideways to pick a column and then send it down one row. The tile it lands on decides what happens next.
Here is a quick example. Holding 9 and stepping onto 3 leaves you with 3. Holding 9 and stepping onto 6 gives you 15, because 6 does not divide 9.
With four rows, you get no more than four drops. If your number hits 1 sooner, the level stops right there. Every board has a fixed layout, so retrying gives you the same tiles to work with.
How grading works
At the end of each level you get a grade. Finishing on 1 earns ACE. Ending anywhere from 2 to 9 earns LOW. Anything from 10 up is graded High.
At the top of the board, the Avg figure averages the final numbers from all the levels you have completed. Lower is better. Since your best run on each level is the one that counts, replaying an old level can pull your average down.
Winning moves
- Look ahead before the first drop. Plan two or three rows deep. Adding a little early can open the door to a much bigger division further down.
- Treat 1 as a free pass. Every number divides by 1 and stays the same, so it lets you skip a row safely.
- Work toward a prime. With 14, dropping onto 2 leaves 7, and a 7 below that finishes the level.
- Restart freely. Swipe up, or press Up, W or K, to restart at no cost if a path goes badly.

Factors Game FAQ
Does Factors Game work on a phone or Chromebook?
Yes. On a phone every move is a swipe, and the tall board fits best with the screen upright. On a Chromebook you can use the arrow keys, A and D with S, or drag with the mouse. Menu screens have big, easy targets.
Is my progress saved?
Yes. Your best result on each level and your overall average are stored in your browser. Every level you finish unlocks the next one, and you can pick any open level again from the selector.
How long does a level take?
Only a few seconds of play. Each board has four rows, so you make at most four drops, and reaching 1 sooner wraps things up right away. Most of the time goes into planning the path.
What if I cannot reach 1?
You still move on. Any finished level unlocks the next, whatever number you end on. A few layouts might make 1 impossible, so aim for the lowest result you can find, then retry later for a better grade.
