Split Puzzle by Feng Gao FREE

Split Puzzle comes from Feng Gao. The object is to split the yellow shape into 2 or 3 pieces that will then fit perfectly onto the dark shape above.

Rules:
1. Shapes can never have less than 2 units.
2. What's never clear: is how many divisions are allowed for each puzzle. Sometimes it's 2 or 3.
3.  If the dark shape has 2 squares with 2 white lines: that means the shapes that fit over them must have the same # of units.
4.  If the dark shape has 2 squares with 3 white lines: the shapes that fit over them must be identical.

There are over 100 levels.  I stopped at level 43 because there was clearly a glitch in the program. I tried to contact the developer, but was unable. So I did the next best thing and reported this glitch in the review section on the App Store.

This game is quite good!
