Start a game by entering the center part of the in-game minigame building for the desired map.

Move up and down in the rightmost column by going onto the top-right or bottom-right teleporters to select your starting cell.

After leaving your starting cell by going onto the top-left or bottom-left teleporters, the game begins and you can move diagonally in all four directions simply by jumping onto the teleporters.

Upon entering one of the two center cells you get moved to the other one immediately to switch sides.

Once you reached the leftmost column you can leave the building in-game to end the game save your score.

If you want to retry without saving, just leave the building without being on the leftmost column.

You can try to increase your score at any time, even if you already had a successful game.
