Tutorials

[Bucky]

The levels in this thread are designed to teach new members some basic tricks.

To new members: In making these levels, I am assuming you have already solved the built-in levels.  If not, please do them before trying the tutorials.

To tutorial writers: Tutorials should both present some examples and give situations which require some creativity in using the examples.

Dozer Tutorial: ragofyk

Good tutorial. Gives some experience with dozers. Especially the "mill" (bottom one of the examples) is a nice trick.
Perhaps you could also create a scene in which the user is forced to use the top example?
Anyway, thanks a lot.

Here's one for adders and subtracters: duzamah
In case anyone can't figure out some of the examples (two or three took about 30 minutes to prove that they actually had solutions), here's the solution: fobobuk. It may be a tutorial, but a few of the examples are quite tricky!

In retrospect, I made some of those puzzles quite hard. I probably should have taken the hard ones and put them into my own puzzle section. In fact, I will now.
