Great game. Small bit of feedback: I'm having trouble distinguishing the + and ÷ symbols (on an iPhone SE 2nd gen.). You might consider making them clearer.

#12I suggest making satisfied equations green (and maybe unsatisfied ones red) as you go, rather than just at the end. There are a lot of equations that are ×1 or ÷1, which is less interesting than it could be. Fractions could be fun.
I got a puzzle with one equation already solved, and only intersecting with one other, so it wasn't actually doing anything. I can't see an identifier to specify which one it is, but it has 11 - 7 = 4 vertically on the left side.
The difficulty seems to plateau pretty quickly.

#13Fun times! I realise the UX might be tricky, but having a way to input things using a keyboard would be cool. Another issue is that multiplicative identity seems to be used too often. That is, too often the equation boils down to something like "8 × 1 = 8" or "5 ÷ 1 = 5". This would ramp up the difficulty considerably faster, though, so you might want to slow down the complexity increase a bit to compensate. Oh, and…
The puzzles get easy again for a bit when two-digit numbers are introduced, but one unknown and one given number is a bit pointless.

#14Seems fun. One suggestion: ensure that the solution is unique. I just got a puzzle with two solutions.

#15I have a puzzle with no correct solution: https://gcdnb.pbrd.co/images/T5vHCnVvd3Da.png?o=1 Edit: I read that as 3-x=3. I would assume that when reading up that should be the case. Reading x-3 with = above it doesn't seem intuitive to me.
You have to read the verticals downwards: 3 = x - 3. There's a note about it in the "↓01" button. Otherwise things like 8 - x = 9 - y vertically would be ambiguous.

#16Beautiful interface! This would be an excellent replacement for the traditional "times table" approach to teaching basic arithmetic. My only suggestion would be to limit multiplication/division by 1, as this makes some puzzles trivially easy to solve by process of elimination.

#17Regarding arithmetic games, I much prefer https://www.chiark.greenend.org.uk/~sgtatham/puzzles/js/keen...
At least half of that preference is the ability to use keyboard controls. The math is also more tailorable to user ability (use the "type" menu), though within each game it goes from hard to easy.

#18This is a really fun and useful app for kids, thank you!

#19Are they randomly generated or you have a curated list? The difficulty increase too slow, but after 10 puzzles it starts to get tricky.
Hi! They are randomly-generated but in a controlled way (e.g. I tell it to make 1 equation with 1 option, or 5 equations with 8 options for some level). I've made the first few levels easy on purpose just to get people used to the game. And yes, it gets very tricky. Specially after 20-25 puzzles. :)
Is there a counter hidden in the page or a JS variable? I think I went further than that but it didn't get any harder.

#20I'm having difficulty telling "+" and "÷" apart when the font gets small.
