So I know there are a lot of free games out there but which one is worth pickng up? No lite games please.
quest of knights on rush was fun for a little. and all ngmoco's games with plus+ have like a free version, those are fun!!! but some get weird.
Tap defense is great, it's even better than some paid tower defense games. Hanoi, that classic stacking puzzler, and Catchamouse 1/2 (1 is free, 2 is either free or $0.99) is really cute and fun.
A few at random... Jelly Car Ramp Champ BaDaBoo Magic Blackboard PapiJump Quick Turn (any holiday) Edition (I like Easter best) most of the stuff on appventcalendar.com
My family really likes Ramp Champ. Me, not so much, but I do find it polished and a total "no brainer" to acquire at free.
