Adventure Realms: Solo Mode

It is finally here...SOLO MODE! The player will face off against the Shadow who is trying to collect points, the elemental stones, and spread Darkness throughout the Realms. The Solo Mode is extremely low upkeep while also being quite difficult to beat.

The Shadow will be spreading darkness throughout the realms while also racing through the dungeon to collect the Elemental Stones. If darkness spreads into each realm, the player immediately loses. However, if the player is able to defeat the Shadow's Final Form, then the player immediately wins. The Solo Mode is only played with the Base Game of Adventure Realms. This only utilizes the base game board and should not be played with the expansion boards.

—description from the publisher

The solo mode is part of "The time trigger" expansion but also sold separately.
