Addicting and fun
I play the games on the train or when I have time to kill, and I never get bored. At the time of writing this, there are just over 10,000 puzzles, and I have finished close to half of them. They add more periodically, but Im almost looking forward to resetting and starting over again from scratch if I ever finish them all. Upgrading isnt necessary, but if you spend a few bucks you can replace ads with a quick input bar which is nice.
