Clear mist off a puzzle board from where the player taps, with a soft edge

Hidden pieces under fog are a classic way to reward a tap. The fog should not blink out tile by tile in a hard square, and it should not pop back when a second tap clears a place nearby. Here is how to clear a widening circle with a soft edge that combines cleanly with other taps.

Why this works

Fog is a thing you push away from a point, and nature has no sharp edges. A soft rim that grows with time feels like a cloud being parted, and keeping the clearest result per spot means a second tap can only help.

When not to use it

Skip it when the fog is a rule, such as hidden traps the player must remember, or when the board is huge and every spot has to be worked out each frame. Reveal whole areas at once instead.
