They play a similar drinking game in ski bars in Austria - you each get 3 swings of the hammer, before passing the hammer on. Last nail left buys a round. Except you have to hit the nails in with the other end of the hammer, the part for pulling out the nails.

I'm not kidding, in the middle of bars they have a big ol' tree stump full of nails

Shipping is part of the problem and but similar games such as cornhole cost $150-$350.
