This is not really a game as much as it is a cool thing to watch. This was discovered (I think) by Andylegate, not me. I'm just posting it.

Simply raise all the columns to the highest position, and lower the middle one to the bottom. This can be a bit tricky, but it's doable. It doesn't have to be all the way down, mid-level will work.

Now fill up the hole with as many jalakblocs as will fit. Avoid large blocs, they aren't very fun...and obviously, it's really hard to get the long blocs in the hole, so don't bother with them. The rest should work fine :)

once you have the maximum of each type of fitting bloc in there, simply lower all the pillars to the bottom. Once you reach the blocs, they start getting pushed through the hole, and it looks like the ground is erupting blocs. Very cool to watch.

A variation of this is to use all large cube blocs, then jump into the hole after them and flatten the columns, you end up standing on a tower of blocs. Very fun :D
