Just a thought about Frogs Legs. Those who play the game a lot will know that after a bit it comes to a stage of filling in squares that have no use, VERY time consuming

How about an option similar to Pass this move (in Go), as in if both players agree, all squares that will not disclose any Frog, get marked in, and the next proper move is taken by who's ever go it would of been if both players had made these moves

Would certainly speed up the game , of course BOTH players must agree before it can happen
