Europe, 1347. A disaster is about to strike. The Black Death reaches Europe, and during the next 4-5 years, the population of Europe will be halved. The players settle in the various regions of Europe, while the plague spreads throughout all of the continent. The players gain help from the various classes of the middle ages: the Peasants provide population growth, the wise Monks keep the rats away, the rich Merchants flee when the plague approaches, the warfare conducted by the Knights spreads the plague to new areas, the Witches control the spread through magic and witchcraft, whereas the Kings avoid the plague by staying in their fortified palaces. But the plague does not make any distinction: when the rats arrive, no one can feel safe. When the plague withdraws and the game ends, the player with the highest surviving population wins. Rattus is a medium-strategy game that takes place in the Dark Ages during the black plague. The players try to hold off the disease. To do this they get help from farmers, magicians, knights, nobles, ... But nothing helps as long as the rats keep coming.
Rattus supports 2–4 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 Rattus is 45 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 Rattus for ages 10 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.
Rattus has a complexity rating of 2.1 out of 5 from BoardGameGeek players, which makes it a medium-light game.
