+p.boxed.
+ Each capture results in an "explosion" through which all surrounding
+ pieces other than pawns are removed from the board.
+
+p.
+ When a piece P captures an opponent figure on some square S, all pieces
+ sitting on a square reachable by a king move from S are removed, including P
+ itself.
+ The pawns, however, remain: they have to be taken directly to disappear.
+
+p.
+ Suicide is forbidden. Thus a king can touch the opponent king and become
+ immune to checks, like on the following diagrams: 1.Rxf5 is impossible.

+h3 End of the game
+
+p There are two ways to win, by decreasing strength order:
+ol
+ li Explode opponent king
+ li Checkmate opponent king
+
+p Explosions have priority: a checkmate followed by a king explosion loses.

+h3 Balancing
+
+p.
+ White has a big advantage in this variant. In order to balance the odds,
+ you can select "Balanced" to let white choose any pawn (any color) to
+ remove before the game starts.
+ The game then continues normally, black playing first.
