4=10 4+

I love everything about this game. First of all, compliments to the developer for making it without ads in any facet of the app I know that that has got to be a major missed financial opportunity but it’s honestly what made me download it. Next I love the simplicity of the game and yet how the game is not going to compromise. What I mean by this is, for example, if there is a puzzle you can’t solve, you get in hint per day but if you’ve already used that hint there is no micro transaction to get more hints you just have give it a day and think over the problem. Lastly I like that there are only a certain amount of level meaning that they aren’t all just meaninglessly generated and these are sequences that are meant to be played and it also prevents people from becoming super addicted. Overall, amazing game, also the only one I’ve reviewed. Couldn’t help it when the pop up for support didn’t even ask to donate to an external link, but just for a review and yes I want to support the developers.

Thank you for your wonderful review. I didn't want to offer more than one solution per day because I wanted people to get deep into the numbers and think about the patterns and connections. No pressure and no comparison, just you and the numbers.

This game has just the right level of novelty, enjoyment, and difficulty. Not a huge math game guy but this one starts simple and stays simple, while the levels themselves present interesting challenges, such as removing symbols for some levels. No ads, nice design, not overbearing in any way. Just a great time-passer.
I used to do this to mailboxes as a kid, except to get to 0. Brings me back. Even though I will likely beat this game within a couple weeks, it's free and worth checking out.

A couple of weeks of gameplay is very good for any game. I'm honored! I will be sure to look into 4=0 soon. Thank you for the nice review db7171 :)

I’m at the age where I’m seriously worried about the onset of Alzheimer’s. I play a few games of different types to keep my brain sharp by needing to solve different puzzles. There is no other game like this I’ve ever seen. Rarely does something this simple but so different come along. I’m looking forward to 5=10 or 3=12 or whatever comes next!

This also fits into the category of “crap! I wish I’d thought of that”

I can't make the claim the game is likely to slow down any kind of cognitive decline. But I hope it boosts confidence and helps people relax. I will most likely add more content in the future. Thank you for a wonderful review and good luck.
