Favorite Game

This game is one of my favorites, I play it daily and always do the traditional and experimental daily challenges. I am also super pleased with their bug fix of the freezing that was happening. That was very frustrating but I'm so glad it was taken care of. Now I play even more! I wish there were more levels for free so I could keep playing but I hit the end of the bundles so now I can only do a few a day. One thing I've thought of is maybe having a hint button and ALSO having the option to disable whether your square is right/wrong. When you put an x Or o in the wrong place the row that is wrong turns red - sometimes the challenge is nice so if there was a feature where you could disable that/turn it on for when you want it that would be super cool.

Thanks for a nice review! Those are good suggestions and we might implement them along with some additional new levels.

Keeps freezing! 😾

When I first downloaded this game, totally loved it. Agreed that hints/error alerts would be nice, but definitely became engrossed. 4.75 stars for my initial experience. Then Apple released a software update (September 2018), and now the game keeps incessantly freezing! The worst part about it is that the game does not auto-save, so when the game freezes/crashes, all progress for the level you were playing is lost! Now, I have to save every few moves so I don’t lose all progress. Once this issue gets fixed, my rating will go back up to my initial 4.75 stars.

Thank you for reviewing! We are sorry that it took us so long to find solution to the issue but it is now live! We are also working on auto-save feature.

Needs hints

I’m addicted to this game, but there’s one flaw. It doesn’t have hints or even a way you can check for errors. It would be really helpful for certain puzzles if I could just have a way to check that I’m on the right track! Otherwise, awesome game!
