New crazy cut puzzles

I recently found out about a simple and fun type of puzzle called a crazy cut, first made famous by Martin Gardner.

The general idea is to take a given shape, and cut it into two pieces with the same shape.  The cut does not have to be a straight line, and the shapes are allowed to be “flipped,” i.e., one shape can be a reflection of the other.  Here’s an example puzzle, with its solution:

Can you find the solutions for each of these four puzzles?

Puzzle number 4 is much harder than the rest.  I’ll post solutions in a few days.

Friends seem to find this puzzle pretty engaging, so I’m thinking about making an iPhone/iPad game with a bunch of these.  Do you guys have any thoughts/ideas on what would make such an app fun?

    I think there’s a game called “slice it” that is kinda similar to what you describe here

    Oh, yea, that’s true, I’ve seen it. They are similar ideas, but I think this one can allow for more complex answers. For example, the solution to puzzle 4 is trickier than might be expected. But I’m really glad to see games like that being made and getting noticed.
