Oh hey Seece I'd like to sign up for the achievement league. My username on Trueachievements is the same as my Gamertag. YO mUThEr

18th member, welcome :)

^^ Thanks Seece.

Hey does anyone know how I can increase my spark play time without paying money? It's really annoying that every level that I want to play requires me to use what they call spark power and I only have 28ish minutes of it.

You can just use the gray stones to do so. I believe it is 30k for 30 days of play.
Also, every day you get back 30m (but it will not go higher if you already have 30m left)

I love this game by the way :) My kids already created a tone of levels and they are not trying to experience with the logic which is really funny to watch!

Same here, already posted but I believe you missed it :)

I Will check Trueachievements and create an account.

Is that your TrueAchievements username?

working on it hehe, that was fast reply

I'm fast :P

I only have 30 graystones >_>

Just play/create some levels. You can accumulate a lot of stones very quickly by just assembling stuff, playing with brains, modeling terrains, etc... :)
