Good game


I was really enjoying the game, but now the app wont let me select play after so long, i uninstalled it and reinstalled and i have the same problem again (did that three times all leading to same prob) all i can do is get to the home screen and select nothing... Its frustrating as i really want to play this! But i see others have no problem, im just unlucky maybe, in anycase what i could play I loved i would deff recommend this, hopefully it will run great for you. I will try reinstalling agin as you never know fourth time lucky 😃

Great, addictive, fun app!


This app is great for killing time but once you stop you won't stop. It's very addictive and doesn't get boring quickly like so many others that are similar. It's got great variation on the puzzles/games too from reaction time to mathematic skills to silly things like pulling toilet roll off the holder quickly enough! It's very fun and I can see why it always gets 5*s!

Can't play the game

Baby dollxxxxxx2010

I purchased the pro version as the free version kept crashing and stuff, however this one isn't much better. The first 10 minutes I could actually play the game was really good and fun, but after that, the screen stopped working, so whenever I open the game I can't press on anything - it's like the screens frozen. Although there are no problems with my phone, I tried completely closing the app and restarting it again, and restarting the phone, but it made no difference. Very poor quality app and waste of 79p. Would not recommend.
