ColorFold comes from Martin Pluisch.  It's a Ribbon puzzle game. The object is to drag the ribbons across the board to cover squares of the same color.  Key: ribbons can be folded, but not over any of the target squares.
Colorbind (see link below) was the first game to utilize this concept. It's outstanding. Sadly, it's no longer available. It came out in 2010. (Theoretically, old ipads that have this game should be worth more!)
Let's get back to ColorFold. It's very similar and very good.

What's different
1. Random black squares are scattered in the grid to prevent the movement of ribbons.
2. Wormholes: this is a common element in puzzle apps, but it's the first one in a ribbon game.
3. Forced Movement: when there are blue and tan ribbons, the blue ribbon forces an opposite movement in tan. Very interesting: there are a few levels where blue can keep going, but tan gets stopped.
There are 100 levels and they're not too hard. Which is good because I like feeling smart.

Here's an idea for future puzzles: how about when a ribbon goes through a wormhole, it comes out with a different color"

Good game Martin!https://itunes.apple.com/us/app/colorfold/id1418593600"mt=8
