nim 
(nĭm)
(nĭm)n.
A game in which players in turn remove small objects from one of several collections, such as matchsticks arranged in rows, and attempt to take, or avoid taking, the last one.
[Perhaps from German nimm, second person sing. imperative of nehmen, to take, from Middle High German nemen, from Old High German neman; see nem- in the Appendix of Indo-European roots.]
