So I loved the game to death. I would play it all the time and now when I open it, it crashes and won't let me play anymore. It shows a blue dot then crashes immediately after. I deleted it and got it again, I've restarted my phone and nothing works.

I've been playing this for months now. It reminds me a lot of Kakuro or Cross Sums (Dell) in that you have to figure out what combination of the given numbers will equal the sums. It's not easy. But it's not impossible. You can buy clues 10 clues for .99 or you can earn 3 clues by watching ads. Every once in a while you get a chance at 5 clues if you watch an ad. The ads aren't intrusive or constant. And I really love the developers for this. It's clear their not out to annoy the crap out of you for the sake of advertiser dollars. The ONLY thing I would like is the option to buy more clues at a time. This is a great calming activity.

I love this game. I’ve had it for ages, the puzzle is unique, I have yet to see a copy of it which is saying a lot! It’s fun and makes you think. I love to come back to it every so often. That said, the game slaps a full, 30 second long ad on you *every time* you leave the app. Got a text to respond to? 30 second ad. Close your phone to talk to someone? Another 30 seconds. If an app is going to *penalize* me for having a life outside of it, it comes across as deeply inconsiderate to players... put ads between puzzles, give me a quick 5 second ad after returning to the app, but do not penalize me as the player for wanting to multitask. That’s pretty darn close to a full dealbreaker for me. It’s just bad design, plain and simple.

I love the game and the ads even after I paid for no more ads was annoying but I found a way around it. For whom this may concern for whoever sees this. The game itself doesn’t need WiFi, cellular or anything to play, just go to settings and turn off “cellular” for this game, can’t give me random ads if ain’t no service going through the game ?
