The Wonderland Board

Here I am again. I have absolutely no patience. I've played this level repeatedly. And I always get the same result. I pickup 28/37 coins and 19/20 bonus. I cannot figure out how to get to the island with the cannon and coilies to pickup the remaining 9 coins and 1 bonus.

I've tried AltX, but from the bottom there are only 6 steel boxes and I can only free 5. Also, boulders expode in lava.

Any hints would be appreciated.

Hi Dee, see if this helps you.

You don't need to build a bridge to the area where the cannons and coileys are. I think you have already built a bridge to the part of the island where the kaboom is circling 6 wooden boxes. You need to trap the kaboom and blow up some of the wooden boxes so that you can move the center box in the top row. There is another timer switch for the yellow gates under that box. Be careful when you open the yellow gates as some of the coileys may come into your area. Once the cannons get rid of the coileys and some get caught in the gates, you can now enter the area, pick up the coins, activate the gate switch at the other end and race out of there to the exit.

Well, Gen,
What can I say. I feel real dumb. I should have known there was a hidden timer when I saw the first. And now I know what the boulders were for.

Thanks, appreciate the hint.
