▁which ▁defines ▁it . ▁It ▁may ▁move ▁a ▁number ▁of ▁spaces ▁equal ▁to ▁the ▁number ▁of ▁pieces ▁in ▁the ▁subgroup . ▁ ▁When ▁a ▁subgroup ▁is ▁moved ▁it ▁must ▁involve ▁one ▁of ▁the ▁end ▁stones . ▁ ▁Pie ces ▁may ▁not ▁move ▁onto ▁an ▁occupied ▁square . ▁ ▁Capt uring ▁an ▁enemy ▁stone ▁ ▁If ▁the ▁first ▁stone ▁in ▁a ▁moving ▁group ▁enc oun ters ▁a ▁single ▁enemy ▁stone , ▁the ▁group ' s ▁movement ▁stops ▁there , ▁and ▁the ▁enemy ▁stone ▁is ▁captured . ▁ ▁If ▁the ▁first ▁stone ▁in ▁a ▁moving ▁group ▁enc oun ters ▁an ▁end ▁stone ▁of ▁an ▁oppon ent ' s ▁group , ▁it ▁can ▁capture ▁that ▁stone ▁if ▁the ▁oppon ent ' s ▁group ▁is ▁smaller . ▁The ▁turn ▁ends . ▁ ▁If ▁it ▁cannot ▁capture ▁the ▁end ▁stone ▁because ▁the ▁oppon ent ' s ▁group ▁is ▁the ▁same ▁size ▁or ▁larger , ▁it ▁is ▁not ▁allowed ▁to ▁move ▁on ▁to ▁that ▁square . ▁ ▁End ▁of ▁the ▁game ▁ ▁A ▁player ▁potentially ▁wins ▁the ▁game ▁if ▁they ▁get ▁a ▁stone ▁on ▁the ▁home ▁row , ▁or ▁row ▁far th est ▁from ▁their ▁side . ▁If ▁their ▁oppon ent ▁cannot ▁get ▁a ▁stone ▁of ▁their ▁own ▁onto ▁the ▁first ▁player ' s ▁home ▁row ▁in ▁their ▁next ▁move , ▁the ▁first ▁player ▁wins . ▁Otherwise , ▁those ▁stones ▁are ▁" locked "; ▁they ▁cannot ▁be ▁moved ▁or ▁captured . ▁The ▁next ▁attempt ▁at ▁crossing , ▁as ▁this ▁is ▁called , ▁will ▁determine ▁the ▁winner ▁( unless ▁it
