Fewest different skills levels can be beaten with

[nobody]

Mayhem 7 can be done with just builders, bashers and diggers (I.E. you don't need the climber).

Well done, you beat me and welcome to the forums!

[nobody]

Thanks  I actually posted here before but I sort of lost touch when they kept changing hosts

Here's a replay, it's a derivative of the 100% <1 minute solution I posted on the old forums. I sort of messed up at the end which cost me an extra lemming but no big deal.  http://www.sendspace.com/file/prz104

Hello nobody, welcome to the forums.. or welcome back.

I don't know if you're aware, but you can post attachment files on these forums. If you click "Additional Options..." on the bottom left while you're posting, you'll find an Attach option. The rest is simple.

Well I'm not sure what difference it makes whether I use sendspace or attatch the replay to my post, but thanks for the tip! 

[Pooty]

Using the attachment system is quicker, easier, and above all, no dodgy adverts with nasty fat bellies on them. They gross me out

Oops, going off-topic. Sorry about that.

Anyway, I can tell you that both solutions I have on that challenge uses only 2 types of skills (not the same combo either).  I'll reveal them when I come back from my cruise next week, in case someone is still working on that challenge.  Or perhaps those solutions will be found before I'm back?  And for this thread, you don't even need to restrict yourself to using exactly 3 skills or not going off the right, so one of the 2-type solution should actually become a bit easier to find.

I just found the second solution to this challenge (after finding the first one shortly after you posted it). The two solutions use blockers + diggers and builders + diggers. The latter of the two is extremely frustrating to execute.

Taxing 22 can be done with 2 skills, by the way - builders + diggers.

Good call on Taxing 22, Clam. By the same token, it can also be done using only builders and the one blocker.

[Clam]

Actually, now you mention that, I just realised you can do floaters + builders and builders + miner too.

Taxing 2: builders, bashers and miners.

How about 2 types: Blockers and Builders.

Mayhem 30 works with blockers, builders and bashers. It was fairly hard but I spared a builder in the end. Here are some hints if you can't do it.

Blockers can be built over (Obvious isn't it?) or bashed underneath.
It takes 7 builders to build to the top of the rock bridge on the left side.
The 10 ton trap can be bashed under.
You don't need to build over the orange rock on the right side, I bashed through it instead and still got to the top.

Mayhem 30 works with blockers, builders and bashers.

I think you could do this without the blockers. I won't try it right now, but I have found a way to turn everyone around at the right using 5 builders and a basher.

He did say in the first post that glitch solutions would be listed separately

[nobody]

It doesn't require any glitches though 

[Minim]

My Mayhem 10 solution uses two diggers breaking the right edge of the wall. Is that clarified as a glitch or not?
