I really don’t like it when I have to watch an ad to get to the next puzzle, but at least the ads are short and the games are free, so it’s not a total deal breaker. If you like KenKen, this is it, even if it doesn’t have the same name.

I loved this game and played it frequently. Now with the new super long ads after each game it is annoying but worse than that they crash the program and force me to delete and reload the program. I understand the need for the ads but if they prevent people from playing the game then how does that benefit anyone? Previously I would have given the game 5 stars but now I have to give it 1. Hopefully this will get the attention of the developers and they’ll fix things.

The only suggestion I have is to allow us to move the calculator around on the screen so as not to block the squares we are working on. Otherwise an outstanding product.

Love level 5 - not too easy but difficult enough to feel satisfying. Levels 6 and 7 are good when I have time.

I’m obsessed with this puzzle. I searched for this type of puzzle after playing similar ones on airline mags. It’s great that it offers you a choice of matrix size. It really challenges your brain, especially the 9x9 grid and trying to solve it without using notations or calculators, so you have to keep it in your head. I also enjoy the random mix of math operators, some addition or multiplication only, others mix it up with subtraction and division. You definitely learn the different logical techniques and I feel my aging brain has actually gotten stronger. My one request would be that if you enter a number accidentally in a square that doesn’t conflict with existing numbers, you could remove it without having the loss applied.

I really love this game but is there any way you could sell an ad free version

My kids see me playing this game and then they want to do it as well. They don’t realize they’re actually learning math.

Really cool, and challenging. You get to do different levels and it doesn’t tell you to go to another one. Highly recommended.

Something changed in ads, I think. Now they are quite long, almost unbearably so. I end up closing the game down instead of watching the ads.

Easiest is multiplication hardest is addition
