Four numbers show how forgiving FindMaster touch controls are. In a spot-the-difference game a small object is easy to find with your eyes but hard to hit with a fingertip, so the game makes the tappable area more generous than the object itself. Every value below was checked in the answer-judging source.

128px: from 5mm to 9mm

Taking the width of one picture as 1000px, the answer area is expanded to at least 128px. A source comment says it used to be 76px, which is about 5mm, smaller than a fingertip. It is now sized to roughly 9mm, like the spot-the-difference games on the market.

26px: next to the object counts too

Another 26px is added around the object’s rectangle on screen. So if you miss a small cup and tap the tabletop beside it, you still score as long as you are inside the area.

Position Difference, “Find 3 differences”: small objects stay tappable thanks to this area.

84px: two answers never overlap

Once areas are enlarged, two answers could overlap. So when a puzzle is built, the game checks that answer centers are at least 84px apart. One tap never catches two answers at once.

2% edge, occlusion, minimum size

An answer candidate has to fit entirely inside the 2% margin of the picture, so an object cut off at a corner cannot be an answer.
An object that is too covered by another object is not a candidate either. A source comment says spots like the floor behind a table are deliberately not created.
Each object has a minimum on-screen size, and that threshold shrinks a little as difficulty rises.

0.45s: when the finger lands twice

A tap near the same spot (distance under 0.05 in picture coordinates) made again within 0.45 seconds is not counted as a wrong answer. It stops one slip from costing two hearts. Tapping an answer you already found is not a wrong answer either.
