Quarters

Edit to previous comment: This particular issue is only for P4 (blue), so squares A4, B4, C4, C5, C6. Who goes first carries quite a bit of momentum early on. Consider having each have one less move at the start: p1 gets one move/territory, p2 gets 2-square move, p3 gets 3, then p4 gets full. Would help a bit, at least. It is an interesting game though, I'd like to see it developed more.

There's a way to ensure one player can be eliminated 2nd turn if his 2 adjacent opponents set themselves up to access any of the 5 squares on his central border (like A3, B3, C3, C2, C1). Then one or both of them are able to take out his territory no matter what move he makes. This could be solved by making your home square not a castle, but normal territory, or just a bigger board (increased moves still may work with this if you choose, since he can camp near himself more effectively as the board size increases). Naturally, undoing and redoing a move ("bickering") allows other players to advance, so that's not usually viable.

Please keep in mind you can spawn scouts from LAND you own, not just castles. And that spawning on a square with 2 of your castles surrounding will empty both castles. Making a castle only captures adjacent squares that are owned. Interesting game. Make something out of it.

I loved it. It was unique and the only thing I did not like about it wa having to refresh to start a new game.

It's a cool puzzle, with some pleasing graphics and sounds - though it could be made better with some extra twists.
