Saboteur is a mining-themed card game, designed by Frederic Moyersoen and first published in 2004.

[1] In the base game, players are assigned either a "Miner" or a "Saboteur" role, and given a mixed hand of path and action cards, and take turns in succession playing one card from their hand (or discarding it) and collecting a new one from the draw pile.

Miners may play a path card in order to progress in building a tunnel from a special card which represents the mine start to one of the three special cards that represent possible gold locations (only one of which is effectively gold, but the players do not know which when the game begins as they are placed face down), while Saboteurs try to play path cards which actually hinder such progress (for example by ending paths or making them turn in opposite directions).

Either role can instead play an action card, which have varying effects such as blocking other players from building paths (breaking their tools, in the game's analogy) or unblocking themselves or other players (usually the ones they believe to share the same role of either Miner or Saboteur).

The extra role card is left face-down until the end of the round.

The start card has one path that touches all four edges and a ladder, representing the entrance from the surface.

In addition, path cards are always played in a portrait (upright) orientation, but may be rotated 180°.

For example, a path card with a green door prevents the blue gold diggers from passing through and vice versa.

In addition, there are several new path cards with a mixture of connected edges and dead ends.

Some of the path cards included with Saboteur 2 feature crystals, which are important to the Geologist role players.
