Sorry for the double post, but it would not all fit in the first.
Watch out for the other Word Quest + out in the app store - NOT the same game...
This one is really a great word search game, and matches the paperback editions in complexity and has a number of modes that can only be done with a computer program.
Take a look at the fill rate, and crossings that are present in just a random game with the high complexity selected in the custom options screen.
Some people may be a little off-put by pricing, but seriously - there is enough content here to play word search games for the next several years, and the developer is adding new themes, and tweaks pretty frequently.
Additionally, this is a universal build, and I can tell you it looks great on the iPad - the screen shot is from the iPad.
I am just trying to get a little love here, as this has been a totally overlooked game, and I can't believe that I am the only person out there that likes word search puzzles.
Additionally there is a lite version as well as the regular version. The regular version you have to purchase themes - and for content, it is much better to just get the plus version unless you are a really casual player.
Lite version may have ads - I don't know, there was a version that did...
