Apply the boss sticker at the back of both their respective tokens (1 for each clan). Those tokens now play like any other explorer tokens but have an ability that can be triggered once per game: In case of a tie, the boss power can be activated to win the territory on which it is located. If both bosses are activated on the same card, no one wins. Promo found in Plato Magazine 109.
Kero: The Boss Variant supports 2 players according to the catalogue. This is the publisher’s listed player count, so the game is designed for exactly that number of participants. Variants for other group sizes, if any, are described in the rulebook of your edition, so check it before setting up a different configuration.
The listed playing time for Kero: The Boss Variant is 30 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 Kero: The Boss Variant for ages 9 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.
