Welcome to the Wall, home of all the cool bricks in the neighborhood.
A brick's life is a tough life unless it's got other bricks around to support it. This map works on the Hordes style of continent bonuses: there are no continents per say, no cards, and no troop bonus for every X territories, so to get a bonus, you must capture groups of bricks -- if you control a brick and all the bricks bordering it, that brick gives you a bonus: small bricks give +1, large bricks give +2 (windows and the hole in the wall do not need to be controlled to receive the Hordes! bonus for neighboring bricks).
Speaking of which, since windows are much more breakable than bricks, they defend with only d4. And the hole is just a hole, not much there in the way of resistance, so it also defends with d4. However, holding any one of these three territories gives a big +5 bonus, but good luck holding onto it!
A few miscellaneous notes:
-Min army bonus is set to 5, elimination bonus set to 20, and 30 units may be held in reserve.
-All territories have a 20 unit maximum.
-The hole in the wall may attack or be attacked by all 12 surrounding bricks. The windows can attack/be attacked by only the bricks directly touching them.
That's pretty much it. It's a brick's life, so enjoy!
