Hextremadura

From BoardGameGeek:

Hextremadura is a solitaire exploration game where you will discover a new land beyond the edges of the Guadiana river. Place the different terrain tiles to achieve every exploration objective at the end of your journey: the perfect score. The game can also be played in cooperative mode. During the early game you will try to complete as many terrain requirements as possible. Every time you complete both basic objectives on a tile, you take that tile off the map and reserve it for later. You will use them on their back, after you finish the stack, to discover all monuments, flora and fauna of this new place and complete as many exploration objectives as you can. This game takes about 1 minute to be learned and 15 minutes to be played on average. -description from the publisher
