Learn how to use the Guest Mice promo set in Rats of Wistar. This guide covers setup, inviting guests, and scoring new strategic options.
Quick answer
The Guest Mice promo set adds four Guest tiles to Rats of Wistar, encouraging you to explore the map and invite guests to your lair for new strategic objectives.
What the Guest Mice tiles add
The Guest Mice expansion is a small promo set that introduces four Guest tiles. These tiles are not part of the base game, so they add variety and new goals to your play sessions. The core rule is that you must explore the map to find guests and invite them to your lair, which can shift your focus from other objectives.
When to use the expansion
Because the Guest Mice set only adds four tiles, it works best when you want a quick change to your Rats of Wistar game without a full expansion. It is ideal for players who enjoy exploration and social interaction over pure resource management. Keep in mind that the tiles do not replace any base game components; they simply slot into your existing setup.
Step-by-step guide to using the Guest Mice expansion
- Set up the base game as usual: Prepare your Rats of Wistar game normally. Shuffle the four Guest tiles into the tile pool or set them aside as specified in your group's rules. Ensure you have the base game ready before adding the promo tiles.
- Draw a Guest tile when exploring: When you would normally draw a tile from the map, you may instead draw a Guest tile. This represents finding a potential guest to invite to your lair. Drawing a Guest tile uses your exploration action, so plan accordingly.
- Invite the guest to your lair: Place the Guest tile in your lair area. This may grant you a special ability or scoring opportunity, as described on the tile. Follow any additional rules printed on the tile. Guests take up space in your lair; manage your capacity.
- Score points for guests at game end: At the end of the game, each Guest tile in your lair may award victory points. Check the tile for its specific scoring condition. Some guests might require you to have certain resources to score fully.
