How do you get through level 18 on silversphere on miniclips?

Answer 1

First hit the box nearest you into the water, go across this box and rescue the next box by sliding it out of the way of the approaching bomb. Leave it there and hit the 3rd box into the water.

Then its a case of working the 'rescued' box down across this bridge, right onto next island, and up, in a position to be slid across onto the 'temple' island. If you slide it so its corner touches the left box (of the two buried in the temples walls), the bomb will destroy them both, leaving you a clear path into the temple and out the top end (using the last box as a bridge to the vortex).
