Standard Arena as in not domination. To give an example of a custom map used for standard 1v1 Arena, there is a map I designed called Road of Battle (shown below), in which secret passages only connect east to west or north to south. Starting positions for this map are at a2 and c5.
If you would like to be added to the list, please let me know!
Or if you would like to submit a new custom map for standard Arena, post it in
Game Board Layouts and if it's good I will link it here.
