You read it right. Create a Ballista level using the easy to use level editor, upload it, make sure it gets approved and you get $1 USD (valid PayPal account required). No strings attached, no scam.
But the main thing to consider is: it must get approved otherwise you won't get your buck.
Well, how do my levels get approved then?
Make sure your level is entertaining, fun, challenging but not impossible to beat. I only approve levels when I need levels and I will do so in batches. So every 30 or 40 levels I receive I will start approving and sending money so don't go mad if you don't receive your money instantly.
Why are you doing this?
Every batch, so 30 or 40 levels I'm going to compile a Ballista Level Pack, so your levels will be used in Ballista level packs. If isn't fair to not thank users for creating these levels and what's better than receiving a reward for it.
So what are you waiting for? Start creating levels!
