Nunatak: Temple of Ice

In the three-dimensional construction game Nunatak: Temple of Ice, you build a step pyramid together in a mountain of ice — but this game isn't co-operative, so watch your step! (A "nunatak", by the way, is a hill or mountain completely surrounded by glacial ice.) For each pillar stone placed, you receive cards with different values that will affect your score in the end. For every four pillars built in a square, a new level of the monument opens up, with the temple of ice growing step by step. Who can place their stones most wisely and rise to the icy challenge?
