Buggy It won't let you play past around a score of 150.000 in Fibonacci mode, but otherwise a great game.
Excellent I love this game very much. It's design is very nice and it works on my mobile efficiently
Malware Cause non stop pop up ads even when app isn't open... until I finally had to do a hard reset to my phone because even a factory reset didn't work.
Big upgrade: - Make to size game play 5x5 and 6x6.
