- Game

This is a game for two players. You will need some small-square grid paper, a die and two felt-tip pens or highlighters.

- Mark a starting point and a target square.
- Players take turns to roll the die, then move that number of squares in a straight line.
- Move only vertically (up/down) or horizontally (across), never diagonally.
- You can cross over the other player's trails. You can trace over the top of the other player's trails.
- You can cross over a single trail of your own, but can never cross a pair of your trails (side-by-side) or trace over your own trail.
- To win, you must roll the exact number needed to finish in the target square. You can never pass through the target square.
- The game ends when a player ends his/her trail in the target square, OR when a player cannot move without breaking any of the rules.

Does it matter where the target is put? Is there a good strategy for winning? If you could choose your own numbers, what would be the shortest possible trail?
