Cthulhu Wars: Tcho-Tcho is an expansion for Cthulhu Wars released in 2017 for 2–5 players, 90 minutes per game, and ages 12 and up. It was designed by Sandy Petersen and its main mechanics are Variable Player Powers, Area Movement, and Dice Rolling.
The Tcho-Tcho Expansion adds a new faction to Cthulhu Wars. The Tcho-Tchos are a human-based faction representing the physically advanced, but ethically repulsive Tcho-Tcho tribe with the ability to interfere with other players by worshipping their Great Old Ones! Your own Great Old One, Ubbo-Sathla, is a tool and slave, not an object of worship! Unique among Cthulhu Wars factions, the Tcho-Tchos have access to three high priests. In addition to the standard power generation and pacing benefits granted by recruiting additional high priests, the Tcho-Tchos exploit this advantage through two spellbooks (Hierophants and Martydom) based around high priests. The other distinction of the Tcho-Tchos is the way they interact with other factions; the spellbooks Tablet of the Gods and Idolotry enable the Tcho-Tcho faction to leech off other players, and Soulless makes your cultists less attractive to capture. The Tcho-Tchos are generally weak defensively at first, but enemies are typically reluctant to attack an Area containing your High Priests (due to Martyrdom). If they don’t send in Great Old Ones, the riff-raff can often be handled with Proto-Shoggoths--particularly with the Terror spellbook. The Tcho-Tchos have a major power advantage in the early game, because you normally spend 0 Power on your Great Old One. This power can be used not only to capture or build Gates, but to place units in enemy Start Areas to harass them with Tablets of the Gods.
Cthulhu Wars: Tcho-Tcho supports 2–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Cthulhu Wars: Tcho-Tcho is 90 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Cthulhu Wars: Tcho-Tcho for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Cthulhu Wars: Tcho-Tcho has a complexity rating of 3.6 out of 5 from BoardGameGeek players, which makes it a medium-weight game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
