Widget Ridge is a steampunk-themed deckbuilding game, traditionally for 2 players (solo mode and extra players supported).

The game follows traditional deckbuilding mechanics of starting with a terrible deck of cards, and improving it with purchases and deck-thinning abilities.

Players take turns generating Gold and making Spark, purchasing new inventions from the Marketplace of Ideas, and combining these in their Workshop to make larger, crazier machines. Players can invent things like a Clockwork-Powered Butter Gun with a Parachute, a Coal-Powered Mechanical Bison with a Grappling Hook, or a Solar-Powered Battle Corset with an Antenna. The game has over 1000 combinations in the initial release.

The basic win condition is to gather 100 Spark, but the game also includes Goal cards that can alter the rules and win condition for additional replay value. Players can choose to concentrate on the game itself, or engage the rich story environment. The game is designed for 2+ players, but will have solo rules in the box.

Widget Ridge: The Fire in Which We Learn, a Story Pack for Widget Ridge, adds new card types to the game.

Characters: allows players to start as a character from Widget Ridge with unique abilities and starting cards.

Locations: These cards are shuffled into the Marketplace deck. When a Location is revealed, it remains on that space, and a new Marketplace card is placed on top. The Location card acts in every way like a blank space, except it has an additional effect. If a Location appears on top of another Location (in the same space), discard the oldest Location. Location cards cannot be melted unless a card or effect specifies.
