Inspired by the Black Easter novellas by James Blish, the aim of Aleph Null is to successfully summon the demonic Prince Baphomet who, when he appears, expects there to be no cards in your hand, the main deck and the discard pile; if there are any cards remaining in these 'zones', you lose. However, 'not losing' in this way doesn't mean that you have won: any cards still in play also count against you - too many and you shall lose also. The sooner you 'win', the better your chance of surviving any due punishment.
