Tawantinsuyu: Book of Challenges is an expansion for Tawantinsuyu: The Inca Empire released in 2022 for 3–4 players, 60–120 minutes per game, and ages 14 and up. Its main mechanics are Hand Management, Set Collection, and Area Majority / Influence.
The Book of Challenges contains 3 variants for experienced players. Two variants were featured during the Tawantinsuyu Digital World Championship 2021 and are therefore uniquely balanced for 4 players. The third variant is not for the faint of heart, likewise representing an expertly crafted challenge. Balanced Symmetrical This is a very balanced game setup for 4 players. It was used during the Tawantinsuyu Digital World Championship 2021 as the setup for the Grand Final. In that particular game, "Bijmeister" secured the win (as player 2) with a final score of 179 points. The player "ooba" clinched second place (as player 4) with 163 points, followed by "Vrarimor" (as player 1) with 144 points, and "Wppxis" (as player 3) with 130 points. Balanced Asymmetrical This is a very balanced game setup for 4 players. It was used during the Tawantinsuyu Digital World Championship 2021 as the setup for the Semifinals. Across the four semifinal games, each player position managed to win their table once, thereby securing a spot in the Grand Final that followed a few days later. Extreme Asymmetry This is an extremely asymmetrical setup for 3–4 players. While it provides each player with an "all stars aligned" start to the game, the players must play expertly to emerge victorious as letting down one's guard can result in another player gaining the advantage.
Tawantinsuyu: Book of Challenges supports 3–4 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 Tawantinsuyu: Book of Challenges is 60–120 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 Tawantinsuyu: Book of Challenges for ages 14 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.
Tawantinsuyu: Book of Challenges belongs to these categories: Expansion for Base-game. Its main mechanics are Hand Management, Set Collection, and Area Majority / Influence. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The catalogue lists Tawantinsuyu: Book of Challenges as an expansion for Tawantinsuyu: The Inca Empire. Expansions add new content, rules or scenarios to the base game and usually cannot be played on their own, so you need Tawantinsuyu: The Inca Empire to use it. Check that your edition of Tawantinsuyu: The Inca Empire is compatible, as some expansions were revised between editions.
