What is "svaika"

Svaika (, marlinspike) was a favorite throwing game of Russian lower-class men up to 20th century. It is a game in which a marlinspike-like spear is thrown to land in the middle of a metal ring lying on the ground some distance away. A tool for the game can weight up to 5 lbs. By one version Tsarevich Dmitry died from a stab wound while he was playing this game.
