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 friendly or an enemy. Hover your pointer over it to check its strength, then either move to another square or attack your enemies. Your ghoul can attack any other ghoul of equal or lesser strength. Note: See below game for instructions and tips.
