Would be good if they didn't tell you the answer after each question...

['t', 'R', 'a', 's', 'S', 'c', 'C', 'g', 'G'] are the easiest to spot IMHO. You can get most of these with the lowercase c alone

By telling the answer after each one they educated me on the difference between Arial and Helvetica. After a coin-flip guess on the first question I got 19/20 right. Now I know the difference.

Yeah, I found comparing the size of the holes in letters like 'a' between the two be the easiest way. Smaller hole is bolder usually from what I saw.

Indeed, although TBH I only noticed at the second to last one!
