<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">jumping game</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for leapfrog that I've seen before include "Overtake in position" , "Vaulting game" , "Child's game of jumping over other children" , "bound over" , "Child's game of jumping over competitors" .)
