The game itself is fun! It could be a nice challenge and a great brain teaser, if it didn’t give you all the answers. When you click a box to fill it, it shows all the number options you can choose inside that box. The issue is when you have already used that number in the row or column, it takes that number out the box and only shows available numbers. After you solve a few numbers, it pretty much has the puzzle solved for you. I don’t want a hint unless I have trouble solving the puzzle but you get one with every box. There is no way to turn this off. I messaged support to ask if I was just missing a setting and they confirmed it can’t be turned off. Because you can use as many hints as you need, this function just feels kind of in the way and for no reason. With the 5x5 puzzles when you figure out 1 or 2 boxes, the game gives you the rest of the answers. There is still a good challenge to the 7x7 ones if you can ignore the hints! I’m kind of forcing myself to ignore the hints but then my adhd kicks in and I can’t help but notice, and it just kind of is annoying. If it weren’t for that this would probably be my favorite number puzzle game! I considered paying for the extra puzzles when I finish the free ones but I just can’t pay for it to just give me the answers. If this doesn’t bother you then you will find this game fun for sure!!

i play this game obsessively! it’s somewhat difficult to learn at first, but once you understand how to solve the puzzles, it’s addicting. you can toggle the size and difficulty of the random puzzles, or you can try their packs for a few bucks—i’ve gotten every single one. plus, it’s available offline, so it’s a perfect airplane game. one of my all time favorites!!!

I really enjoy puzzle games. Very few games force me to think outside the box though. That is, until I stumbled upon this gem. I honestly don’t think there’s a single flaw in this game. It’s such a simple idea, that was executed so incredibly well. Easy to learn, hard to master. I like to believe I’m pretty good at this game, and routinely play higher difficulty levels. However, unlike most games, this one always manages to stump me again and again. I highly recommend anyone who enjoys the free puzzles to purchase the puzzle generator. It’s super customizable, to make it as easy or as hard as you want and you’ll never run out of puzzles to solve. Shame on you developer for making such an addicting game!! Jokes aside, I wish we had more masterpieces like this.
