Add a button "Generate" in the field designer that will ask for a length and a difficulty of the arena. Then the system will automatically generate an arena for the desired size, length and difficulty. For line this requires that the tiles have a difficulty scored. The system could potentially learn from the point of lack of progress about what tiles are difficult.
For maze the length and difficulty are also relevant, but it needs to be defined what makes a maze arena difficult.
