As I've already mentioned on the site earlier today, Astroslugs Deluxe has gone free for today only and is well worth a download if you're a puzzle fan.
The game is similar to the Infection game from 7th Guest (itself remade as a stand-alone iPad game) and can get fiendishly difficult in later levels.
This app being made free is all down to the good people at FreeAppADay, which has saved me a pretty penny since they started making top games free for a day. Also on their cards is a tower defence game with a distinctly Chinese flavour.
Three Kingdoms TD is a universal app which takes traditional TD gameplay and adds some lovely visuals and some nice strategic elements to the game.
You can check out these and more free Apps over at FreeAppADay's website.
