Fencer, where did the rules for this game come from?

Why I ask is that I think there should be some sort of rule the the first from removed from the game must be at least 3 rows from the edge, that way the 2nd player will have at least 4 possible jumps the next time.

Otherwise, a person can just take the from from the corner leaving the 2nd person with only 2 possible moves. And if a "high" value frog is 1 space diagnal from the corner, it now belongs to player 1.
