Mononoke is a semi-cooperative bluffing game where players take the role of heroes defending a cursed castle from mysterious Yōkai of Japanese legend. As night approaches, only one hero at a time can take watch and see the spirit approach.
Only they know the spirit's strength and whether it is friend or foe, and it's up to them to rally their allies... or lead them to their own destruction.
Using a unique blind bidding combat mechanic and partial information about your enemies, Mononoke is a parable about trust and teamwork. If the castle falls, no player can win, but if you play it too safe, you may be left in the dust as another player rises to the top.
