Tips and strategy
- Start from crystals in the corners and along the edges; they have the fewest possible routes.
- Remember you must fill the whole board. A level is only solved when every cell is covered.
- If two paths seem forced to cross, one of them is wrong. Back up and re-route.
- Sometimes the long, winding path is the key, because it uses up space a short route would waste.
- On No Mistakes, slow right down. On Speed Run, trust your first instinct.
