Why a set list instead of random boards
Unlimited mode hands you a fresh board whenever you want one, which is perfect for a quick session. This list is for people who would rather work through something with a beginning and an end. Each board has a name, the set runs from easy to hard, and the counter at the top keeps score of how far you have got.

How the difficulty is set
What sets the difficulty is how many numbers the board gives you. More numbers means shorter stretches to work out between them. Easy boards carry eight numbers, medium six and hard five, so on a hard board you are routing a long way on your own before the next number confirms you were right. Walls help in every case, and every board is checked to have exactly one path.
