About the game

What you do in a play session

Steam Power: Cat Power arrives as the first expansion for the beloved Steam Power, adding two new whimsical cat‑themed maps and an unexpected twist: sleeping cats that may block your tracks. The core game stays the same – you still lay hexagonal rails, build transportation routes and fulfill contracts – but waking a sleeping cat introduces an extra puzzle that forces you to rethink tile placement. Each map features a variable set‑up, so the board changes every play, keeping strategies fresh. The sleeping felines act as temporary obstacles; once awakened, you can move or remove them, opening up chainable routes that award extra points. The pick‑up‑and‑deliver mechanic remains, but now cats can serve as "cargo" that, when delivered to the right destination, grant bonus scoring. The expansion retains the lighthearted theme with amusing engineer‑cat artwork while still offering strategic depth through chaining, connections, and ownership of lines. Perfect for fans of the base game who want a dash of feline chaos without a steep learning curve. With a weight of 2.25/5, the learning curve stays gentle, and playtime ranges from 45 to 90 minutes depending on player count (2‑5). In short, Cat Power adds variety, humor, and an extra layer of challenge that appeals to both newcomers and seasoned Steam Power players.
