Removed fog mechanics, since the only use of it is to hide the cages. Title change.

I don't think this puzzle gains anything from the Fog Of War mechanic. It didn't make the solve more interesting or complex, just more tedious. I think it would have been a better puzzle if the grid was simply shown.

These smaller format puzzles always seem to be more challenging than 1 star! Very nice puzzle, interesting use of the 5th digit :)

I agree that the rules are confusing. Maybe "one digit must be placed" instead of "one digit is placed" would be clearer?

What the fog say?
Edit: I feel like I've cheated a little bit by seeing this puzzle in its earlier form before you changed it but I won't reveal what was different :)
In fact I feel like it's gotten much harder than 1 star now
