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.
