coan.net: Frog Legs is missing something - it ends up being a very long drawn out game.

IMO, this comes from the fact that it doesn't pay to reveal information.
And that stems from the fact that after you reveal information, your
opponent will be the first one to be able to use it. So, if you make a
move that reveals information from which the location of a frog can be
deduced, your opponent will score, not you.

That is, IMO, the essential flaw in the game. None of the suggestions
that assign different number of points is going to resolve it. Neither
is the auto revealing of squares neighbouring a 0 - that will make the
game shorter, but it still doesn't pay to reveal information.

I can think of one rule change which may fix that: after shooting, you
have the option of guessing as well. So ones turn is one of:

• Shoot
• Shoot, then guess
• Guess

Thus, if your shot reveals information that locates the position of a frog, you're the first one that can use this information.
