+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.
+
+p
+ | Note: since suicide is forbidden, a king can touch the opponent king -
+ | and become immune to checks.
