"Trick-or-Treat Adventure Quest" very well may be one of the largest, if not THE largest, flash games you've ever played. You are Little Johnny, a kid in dire need of a Halloween costume who has to make do with what he can put together using household supplies. Once you have your costume pieced together, out into the real world you go for some Trick-or-Treating! But this isn't your average night in suburbia... many strange things are afoot and it's up to you to solve the puzzles if you want to enjoy all the delicious Halloween candies!

A wide variety of puzzles to solve, inventory items to combine, characters to interact with, big bad guys to battle and more can all be found in this big Halloweeny adventure! Since it's unlikely (though not impossible) that you'll finish this game in one sitting, we've thrown in a handy auto-save feature. That's right, you can close your browser window and then load up the game again later on and it will pick up right where you left off! In other words, play the game, but make time for some real Trick-or-Treating too!
