A nice game for me to practice my math! I kinda wish there is less rng involved. One way I can think of to reduce the rng is by allowing the player to save a number and use it later. Goob job on finishing the game, it is impressive you do it in one day!


This game was nice to play! I discovered that you are doing integer math, so -3 / -2 would make me win :D

Keep up the good work!


Thank you! I thought about having decimal math, but I felt that would close it off to a lot of people and move the game into being hardcore math territory for some players. Besides, I couldn't figure out a way to process all the impossible gamestates, so I decided not to, and simply added a math.floor() call, (which by the way should be a math.round() call but the jam ended before I could fix that) which seemed to work fine.


Looks like i'm a right whiz at math! Hehe

Actually i just got really lucky, but don't tell anyone.

Got me a second to actually understand what was going on, but when i got it it was on. The premise is quite simple- make the tally get only a one, by any means necessary. And those means are m a t h s.

Dog gammit i suck at maths, apparently. The music and the timer do have quite an effect on you, though, and the whole thing feels actually quite tense, and that makes you fail a lot, which can get really funny. Maybe i'm just sleepy, though it probably was the music.

You can get really screwed by RNG, i tell you that! Specially with multiple "*"s.

One thing i'd add is to make numbers you don't use stay in the bar. It would add a little bit of strategy (saving those -1s and 1s, forcing you to lose points and moves to have to get rid of numbers that you don't want, etc!)  and maybe let you see the next addition, therefore having to plan ahead your moves. Though maybe you actually wanted to make it like this and that's ok, as it is certainly tougher!

Quite tense math fun. Pretty good!


Hihihi. Thank you for playing. I wasn't sure which to randomise, all three buttons, or just the one that was clicked. I guess it was the second option, because tbh you totally can win through random button mashing and reducing the RNG-reliance would've been better.

I believe i'll implement both your suggestions. I was unsure of my music selection, but not so much anymore, so thanks :P I was really uncertain whether to let this be a one-off or continue work, but reading all of your kind comments and suggestions has cemented me in my decision to continue, and for that I thank you also.

Also, I believe i'll stop the rng from messing up like that, with the strings of *s and /s.

Once again, thanks for playing and for your suggestions, you would not believe how much they mean to me <3 <3 <3


This is an engaging maths game! At the start I was trying to construct the biggest number I could (too many idle games recently) but then going for the actual goal it makes it into an interesting puzzle game. Since you don't know what is coming you just have to hope you are heading in the right direction and the time limit means you can't ponder it for too long. Nice work making something fun out of something so simple!


Full disclosure; Team Spaghetti does not endorse recreational math. We're more of a "Guestimate with our feelings" kinda group. We made a game about a bullet who wants to make his mom proud and screams in terror midflight, if that helps you picture my mental state.

That said, this is not a bad math game, by any stretch. It's no "Math Blaster" but it's dynamically engaging once you get your head wrapped around it. Speaking as the team's programmer, this is the sort of game I'd probably have more fun picking apart the codebase of than actually playing but again; I don't do math for fun. I do math to facillitate the fun things. That's just me.

Insofar as critiques and things to work on, some have brought up the UI and yeah, that's not amazing, but it's well within 48-hour jam territory for me. That's fine. The big thing from my experience was being dropped straight into a ten second countdown and immediately being under time pressure to parse all the things happening on the screen--many of which being wholly unimportant. That's how you give anxiety attacks to the math-averse.

On the whole, is this my kinda game? Personally no! But I can't deny that there's a certain level of mathamagical wizardry that makes it work, and work fairly well for what it is. 


If you would like source, say no more. It's a bit... Spaghetti, no offense to you and yours, but I was on a time crunch, OKAY?! DM'ed it to you on Discord.

The UI will undergo a complete overhaul, I am simply waiting for the jam to end, kinda like a self-enforced sabbatical. And yes, there really really needs to be a start screen and a tutorial, those are the two things i would add if i only had two additions. I learned a ton of things this time - the most important of which is that things I make are only intuitive to me because I made them, and I really need to work on treating stuff as if there was a crazed psycho with a knife ready to stab me if he didn't understand what I'd done.

Thank you for playing, and more importantly for feeding back :D.

Also, I (completely without sarcasm) think you should do video game reviews. And I had a ton of fun picturing your mental state. :DDD


... The most fun I have had with math...


Cool game! Kind of reminds me of a TV show where people needed to find a number doing operations with other numbers. Nice job!


I did not understand it at first (same problem as edmond00) but after I read the instruction, googled for a translation of tally mark and understood what was going on, I liked it!

Unfortunately, the game does not let you divide by 0 and instead shows "pick a number first". It would have been cool if something more elaborated happened (like "that was 1 cool idea, bro...").

But still a very small and neet idea. 


Thank you for playing! I would have liked to work on the UI more, but I was in a crunch since I only had about 24 hours to work on the game due to unavoidable commitments. When I update after the jam is over, I'll be sure to add a tutorial or similar :)

The division by zero... Internally, it causes the question variable to become NaN (Not a Number), and so the NaN checking for whether the user has selected a number or not takes over. I would have loved to add a little Easter egg, like making the number equal to infinity, but again, didn't have time.

I never thought about the problem of the player not knowing to translate tally marks... Where i live, tally marks are taught at school and I never realised it might not be the same elsewhere.

Once more, thank you for your valuable feedback, and I hope you have more fun with the game when it's in a more polished state in the future!


Nice idea, I liked it ! At first, he score counter was confusing as it keep increasing even if you just pick random number so it distract me of the main goal. Once I understood that all the operations were linked and that I needed to get a result of one, it became interesting and challenging. There is only the division by a large number that feels a little like cheating as it will put most of the number to one. Good job !


Thank you for playing! I would have liked to have a decimal calculation system, but I worried that it wouldn't be fun to play as the player would have to do decimal calculations mentally. The score system kind of backfired because I was supposed to replace it with the moves system but didn't remove it at the last minute and then the jam closed.

If I end up rereleasing the game as a standalone title, I'll probably fix it and make the number generation AI better.

Once more, thank you for playing, and for your feedback!


Well designed game for people who have intrest in Math. I thank the creator of this game for giving the world this great place to improve their math skill in an innovative way.


thank you so much! Means a lot! :)
