Fun game, with one issue!

Very fun game to keep the mind active. I’ve enjoyed clearing the board several times now. However, the game sometimes crashes and the only way I can get it to stop is starting a new game. If not for this glitch, it would be wonderful!

Oh god the agony

Getting testy with tenfold

I fell in love with this game very quickly. I was flat out addicted. So much so that I got to the 103rd round. At which point, the game crashes. No matter what I do it will crash. I restarted my phone, I have the most up to date version installed, and for some reason whenever I try to get the next round it crashes. This is incredibly frustrating. The only way I know of to stop it from glitching is to start a new game. However, being at the point of round 103, I don't want to delete all my progress. This is also not the first time it has happened. This happened twice before each when I got to round 103. Other than that I love this app. It is addictive and has a great concept and execution.

could be a lot better


This is basically Numberama... but, I do like the visual format. Where Numberama is a lot better is that you get a blinking arrow that lets you know you have cleared all you can before you add more numbers. This would be helpful to add for Tenfold. Also, if you need to, you can find out how many pairs you have left in Numberama. I don't us that feature anymore, but I did when I started with Numberama. And, Numberama gives you a "random" option so you don't have to play the same game over and over again. Other than that, I like it ;)
