Lms Impossible Letter

Lms Impossible Letter is a fun and challenging spot-the-difference game where you have to look through a bunch of characters and find the ones that shouldn't be there. If you have 4 letters in a 2 x 2 grid and one of the letters is different from the others, your task is to touch it to advance to the next level.
Everything changes once you see a 10 x 10 or larger letter E, but only one is actually an F. The small difference in the small horizontal line at the bottom will be very inconspicuous, but this is where your positional visual recognition skills come into play.
