Old game about underground dwarves?

I had this very old (from the 90’s) puzzle/strategy game about some dwarves that moved underground because of some disaster. And it was up to you to build their community under the ground by planting food, build houses, make storages and stuff like that, and to dig trough the underground to make more space and to get these puzzles. You needed to solve this puzzles to get a piece of an altar or something like that, and if you had completed the altar (after about a 100 puzzles) your dwarves where able to go back to the surface. Unfortunatly I lost that game, and I can’t recall the name of that game. It is NOT brave dwarves, dwarve fortress, diggles or dwarfs!?. Who knows the name of the game that I mean?
