Factor Slicer
Times tables, with a sword.
Numbers fly up out of the city. Your blade has a number. Slice the ones it goes into and leave the rest, or the blade bounces off with a CLANK. Every cut says the times table back, like 3 × 8 = 24.
Android first. Plays offline. No account.
Swipe through the numbers your blade goes into.

One number. Two blades.
Isn't this just a worksheet with a sword?
No. There's nothing to type. Every number on screen is a yes-or-no times-table question, and you answer it with a swipe. Get it wrong and the blade bounces off. Our kids played it because they liked it, not because anyone told them to practise.
Three hearts. The blade changes every wave, the numbers get bigger, and it gets fast.
Three minutes on the clock and you can't lose. Small numbers, and the score keeps adding up. Our 8-year-old asked for this one.
The kid with the blade
He's based on our son, drawn as a hoodie ninja, and he reacts to every cut.
Five styles. Kids pick.
We drew it five ways and couldn't decide. Neither could our kids, so now they get to pick, and all five are free.
For parents
- It plays offline. Nothing to sign up for, no account.
- It's free. Between runs it sometimes shows a card for one of our other games, never in the middle of one and never more than once every three minutes.
- There's nothing to buy, and going to a store from one of those cards asks a grown-up question first.
- High scores stay on the device.
- It isn't out yet. Android comes first, then iPhone and iPad.

What are the factors of 24?
1, 2, 3, 4, 6, 8, 12 and 24. They pair up as 1 × 24, 2 × 12, 3 × 8 and 4 × 6. In the game the 2, 3, 4, 6 and 8 blades all cut 24, and the 5, 7 and 9 blades bounce off.
Is there a trick for the 7 times table?
The one kids remember is 56 = 7 × 8: write 5, 6, 7, 8 in a row. The rest comes from practice, which is what the 7 blade is for.
What's the divisibility rule for 3?
Add up the digits. If 3 goes into that, 3 goes into the whole number. 51 is 5 + 1 = 6, so 51 is 3 × 17, even though it looks prime.
Is Factor Slicer out yet?
Not yet. Our kids are playtesting it now. Android comes first.
