Great but... There is serious lag. I get errors because I do the same move over and over and when it finally catches up it counts each one. It also makes my time longer since I have to wait for it. It isn't my phone, my other apps run fine. I have a Note5.
Have deducted stars for harassment. Continuing to bother people for ratings after they've given one is bothersome. Next time, I will lower rating to 1 star and uninstall. Game itself is good.
Super addicting and challenging some of the levels seem hard but the answer is simple takes a lot of patience but worth it. Definitely an app I would highly recommend for someone looking for a fun challenging number puzzle game
Frustrated Game freezes and consequently causes errors and increases my time. It's useless to try and beat the clock because of the malfunctions.
Like It freezes sometimes, but I like it.
