Dinamine

From BoardGameGeek:

Become a jewel hunter and mine building master! In the basement of your castle is the entrance of an old mine. Dig into the depth of the earth in search for gems. The deeper you go, the more valuable these will be. Dinamine is a mine building strategy game for 2-4 players. The goal is to build the most valuable mine in 10 rounds. Players must build tunnels and mine veins. The deeper the veins, the more valuable the gems that are mined from them. On each turn, a player will build one or more tunnels in their mine by obtaining tunnel tiles that add up to the number of points obtained from round token + dice roll. The tiles chosen must be of equal or lesser value, as long as the number of points acquired does not exceed the value of the tunnel tile(s). In some cases, players can perform an extra action depending on the tile type. The game ends when the last round token is played. (There are 10 rounds) The victory point (VP) count is then performed to determine who is the winner. The player with the most victory points (VP) after counting veins, altars, wells, rewards, items and missions is the winner!
