A promo card for the 2018 R&D Games boardgame Key Flow, issued by German games magazine Spielbox, Spring 2019. When setting up Key Flow, add the keylector to the deck of Winter K cards. The keylector scores 2 points for each of the following that the owner has allocated to the keylector: sheep, pig, cow, iron resource, stone resource, wood resource, anvil skill tile, pickaxe skill tile, and saw skill tile. Only 1 item of each type can be allocated to the keylector.
Key Flow: Keylector supports 2–6 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 Key Flow: Keylector is 45–75 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 Key Flow: Keylector 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.
Key Flow: Keylector has a complexity rating of 3.0 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.

The catalogue lists Key Flow: Keylector as an expansion for Key Flow.
