Nice one, cheers.

Well, the easiest 'puzzle' to make is just a trivia quiz on Itstoohard, but of course these are mostly easily solved with a bit of Googling.

I'll leave you a puzzle hint here instead of on the thread. Mostly because I'm lazy and was already writing stuff here.
I find that simple puzzles work best. As such, a simple "istoohard" puzzle would be a great way to start. Then you just need to think up some questions.
For the questions, I propose having a theme. Be it about a single game world/lore, or guessing a single word from a sentence matters little; the theme is important (unless you want to screw over your participants, in which case, make each question either a) completely independant or b) dependant of one another, even without a theme).

Then there's the "forum puzzle"-type puzzles, where you hide hints to the giveaway url inside the thread. For this, I suggest looking a similar threads. A good one is simply hiding the link somewhere. Another is capitalizing certain words/letters in a sentence to match up with the giveaway URL.
You can also send your participants on a chase around the internet (and google) by referring them to, say, youtube and from there somewhere else. These are also fun.
You can also draw inspiration from this guy although dang, I didn't even realize there were a puzzle going on. :P

In any case, I suggest starting small and building up. The best puzzles require time to make; and possibly preperation. And as soon as you're on a roll (from building up) you'll have an easier time making the harder/more involving puzzles.

Anyways!
Cheers,
Doobs.

Thanks a lot!

Thanks! Don't try to create puzzles even you can't do yourself. You don't want to drive yourself crazy. lol

Pretty good puzzle ;)

Thank you :)
