You try to get all your wizards inside of Ravenskeep. Each card you play may allow you to move 1 of your wizards an exact number of steps, and to enter Ravenskeep, your wizard must move exactly to the Ravenskeep space.

Additionally, you need to fill all your bottles. You fill a bottle, if you move a tower on top of another tower with at least 1 wizard, you capture them, and fill 1 of your bottles.

Later on you may spend your filled bottles to cast Spells, but most importantly is that you must NOT have any empty bottles to win.
