Jump Down is yet another cool new skill game in 3d you can play here, which is in the vein of the really popular Helix Jump Games online, because just like in those, you are going to be slowly descending using your ball, jumping down from one layer to another, trying to reach as further in the deep as possible, and getting a big score in return.
Use the right and left arrow keys to rotate the platforms around, so that the ball goes through the empty space and falls down to the next layer, and so forth, getting points the more you descend. Make sure to avoid bumping the ball into the red spots on the helix, or it melts, you lose, and have to start all over again.
How far do you think you can reach? Do you think you can go really deep? Try out, and make sure to tell us in the comments what was the biggest number of points you made, and maybe compare yourself to other players!
