Level 100 and secret levels

Just figured out paddock 100.  Thanks again for the great game.
 
(I'm the anonymous person above.)
 
Would still like to know how to find the secret levels I've missed!

 There is actually a hint for each secret level on the main map itself :)  Once you know it is quite obvious which levels to look closer at.

I'm stuck on Padlock 100 (iPhone version). I'm overwhelmed by the number of sheep! Any hints??
Thanks!

There are a lot of sheep aren't they! Before I created that level the code only allowed for up to 9 sheep so bits of the code had to be adjusted especially for this superlevel!
 
Anyway hints... It is hard because it is such a mental level! I assume you have had no trouble getting the big sheep to the exit? The next thing is that you don't need to waste time trying to colour change any of the little sheep, actually that might not even be possible given where the colour changer has to go...
 
The key is to switch the black switches an odd number of times so that the gates will all be open. Since the big sheep will flick three switches that means you have to get the little black sheep to flick no black switches or switch them an even number of times so work towards that. Check that every little black sheep has a path home and then check how many of them switch a black switch and make sure it's an even number :)
 
In my opinion this level is really trial and error but I do know of players who have got it first time and just nutted it out, very clever players I would say.
 
Anyway you're doing awesomely to make it this far so hopefully you can figure it out, if not call back and I'll be happy to provide further hints.
 
P.S. My solution even has a leftover little black pipe so there is some leeway and more than likely there are multiple solutions.

Ugh.  Yes, I'd already seen the hints on the maps, but the little shinies you're supposed to run over just don't show up against the white background on the iphone app.
 
And now that I've beat level 100, I get that little uninterruptible movie to pop up every time I solve a level without discovering the secret paddocks.
 
Oh well.  Thanks anyway.

Hi PJ,
 
Of the three secrets on the snowy island which ones do you still need to find?
 
You'll be pleased to know that we are submitting an update today that, among many other things, addresses your annoyance at the video popping up all the time. With this update you'll only see the video once when you first complete the 100 main levels.

Excellent!  I'll see if I can find them now.  I never found any of the secret paddocks on the snowy island.  Thanks for putting more effort into the game!

Without telling you exactly which levels to look in...
 
The first snow secret requires you to take a different path around the tree, you'll miss out on getting the flowers but will unlock the secret.
 
The second snow secret can be found by the white sheep if it avoids all the switches. The black sheep will get stuck and be sacrificed but this is fine since only one sheep needs to be saved.
 
The third and final snow secret is found on quite a complex level (but one that has alternative easy solutions). If you do the level using all pieces in the shop and following the "suggested" path all the way round the board you can't avoid the secret.
 
Hopefully not too cryptic! Trying not to make it too easy for you :) Let me know if you need further help.

 p.s. If you hadn't figured it out yet, the little sign posts on the main map mark that a secret is close by :)
