ruk_shukRukshuk, by Malcolm Bisiker, published by the company he formed called Zabazoo, comes with rocks, cards, and a timer. And by rocks, I mean rocks. Rock rocks. Stone rocks.

Your job is to pick some rocks and a card, and then balance as many rocks as you can in the formation on the card before the timer runs out. Different colored rocks are harder or easier to place and so earn different points if used.
