In Tomb Chess, your goal is to wipe out the enemy's undead army in the graveyard. Start by clicking a tomb to raise a ghoul. There's a 50/50 chance as to whether it'll be a friendly or enemy ghoul. Hover your pointer over the ghoul to check the ghoul's strength, then use it to attack the enemies. Your ghoul can attack any other ghoul of equal or lesser strength. A special note that pawn ghouls can attack the king, but the king can't attack pawns.
Controls: Mouse to select graves or undead and choose attack.
