Tangles

History

This beautifully coded puzzle was produced by Robey Holderith and Rachael Bergstad in the USA around 2011. They have since updated it to HTML5 and, as this is just a sample, I recommend you visit their website at http://flaminglunchbox.net/ for the full range of variations.

How to start

On each tile there is a blue and a green line. The tiles can be rotated by a click or tap. The aim is to connect the lines so that each colour runs from tile to tile around the board with no dead ends or discontinuities. If you think you have solved the puzzle but you don’t see the 'Congratulations' message, then you need to look carefully again because something is not right!

Hint

Start at the edges (you have probably guessed this right away).
