My 2 cents on how to make Frog Legs a game that is not annoying (and fun!) to play: as soon as you "shoot" a Zero, all neighbouring spaces that are also Zero are uncovered (like in Minesweeper).
Option 2: have the same setup of frogs for each player. However, each player only uncovers frogs in his/her own board (and thus doesn't know what the other player is uncovering). Once a frog is found, it is uncovered for both players and the points are awarded for the player who found the frog. The same goes if a frog is killed. Winner is who has more points after all frogs are saved/killed.
