Cavum

In the mountain there are veins of precious stones. The players build tunnels in the mountain, establish stations in the mountain and in the city, discover veins of precious stones, acquire precious stones, and sell them. The players get points for stations in the city and for selling precious stones. The winner is the player with the most points.

Game Summary

The board is a hex grid, with city spaces along most of the edges. The center hex is a vein of yellow gems: place all 9 in a stack there. The rest of the gems go in their individual market areas (priced 1-9 based on supply).Each round (3 in game), add 5 contracts (showing gem combinations; score big VP if completing them; lose some VP if cannot) to the display. Then auction (using VP) turn order chips 1-4. Players then each get the same set of tiles (hexes with various numbers of track exits, prospecting tiles, veins, option tiles, etc.) plus a dynamite hex based on their turn order chip. Take turns taking contracts until everyone passes.

Then, on your turn, play 1-4 of your 12 actions. These allow you to place tracks (expanding previous tunnels; you can also cover track tiles with tiles having more exits), stations, or veins (which you supply with gems of your choice). Gems (6 types, 9 tokens each) each have their own market where they are stored and which set their max sell price. The last action is prospecting, where you create a path from one of your stations to another, passing through as many veins as possible: take one gem from each vein.
