From Karma World:
Tangled Twist is an addictive puzzle game of untangling the web of lines and gems. It starts simple but provides increasingly challenging puzzles.
The red lines indicate that there are intersections, lines turn to green when they are not intersecting. When all green lines are connected to a gem it changes its color to indicate that you are closer to solving the puzzle. The number of gems and lines increases steadily, making the game quite a challenge.
