Kerning is all about the spacing of letters in a typeface. Here’s a quick game to test your Kerning Mettle. There are a few more type/design games to check out, if you follow some links, as well.
P.S. I scored an 80 on my first go (actually it was an 81, but I loathe odd numbers). If you beat me let me know…so that I can mark you for early extermination if I ever gain ultimate power over life and death.
