I just wanted to chime in and say that Ultimate Phonics by Spencer Learning is on a free trial right now, I have no idea how long it will last. This program is good for abilities ranging from Pre-K up. As it lets you practice only certain features and each lesson focuses on some phonic sound, so if tricky endings such as "ture" "tion" or "ure" are your problem you can work on those lessons only http://spencerlearning.com/ultimate-phonics/free-program.html Thats the link/url to get the demo its 10 days for Mac or PC, plus there is a $10 off coupon code that you can use if you decide to buy the program after your trial, which brings the price down from an affordable $70 to a VERY affordable $60 bucks . This is not "edutainment" it is systematic, thorough, and it looks like its good for spelling, phonics, and vocabulary. Even if you dont purchase the program, they have some very good free resources. There is an Ebook that shows indepth the entire scope of the program. I downloaded it on another laptop and plan to use for the next 10 days to see if its as good as I've been hoping.
