The Impossible Letter is a fun and highly challenging find the difference game where you have to look at a bunch of characters and figure out which one shouldn't be there. If you have 4 letters in a 2 by 2 grid, and one of those letters is different from the others, your task will be to touch it to go to the next level. Sounds pretty easy for now, but wait until you reach level 50 of this free online game.
Everything changes once you're looking at a 10 by 10 grid or more of the letter E, but only one of them is actually an F. The small difference of the horizontal little line on the bottom will be very inconspicuous, but that's where your visual recognition skills come into play. Reach the highest level possible and share your result on social networks. Have fun playing The Impossible Letter online and for free on Silvergames.com!
