Actually, more of a "find the object" in a 10x10 grid.
You have 21 guesses but you should be able to find all 4 egg within 10 guesses.
BUT, look out for the hidden Black Egg... If you find it, you loose!
There are no clues, only luck...
S, s, or Select your way through to the end...
(Yes, That's the commands)
Or you can click on the box and Select from there...

If anyone wants to use the idea for a puzzle lock for a door, you are welcome to it...
(But the code will need a MAJOR tweak to run better!)
