2 | Each capture results in an "explosion" through which all surrounding |
| 3 | pieces other than pawns are removed from the board. | |

6 | When a piece P captures an opponent figure on some square S, all pieces |
| 7 | sitting on a square reachable by a king move from S are removed, including P | |
| 8 | itself. | |
| 9 | The pawns, however, remain: they have to be taken directly to disappear. | |

12 | Suicide is forbidden. Thus a king can touch the opponent king and become |
| 13 | immune to checks, like on the following diagrams: 1.Rxf5 is impossible. | |

26 | li Explode opponent king |
| 27 | li Checkmate opponent king | |

| 29 | p Explosions have priority: a checkmate followed by a king explosion loses. | |

| 41 | White has a big advantage in this variant. In order to balance the odds, | |
| 42 | you can select "Balanced" to let white choose any pawn (any color) to | |
| 43 | remove before the game starts. | |
| 44 | The game then continues normally, black playing first. | |
