I did much better this time than I did the last time this was posted. The trick is to pay attention to the negative space more than the letterforms themselves; if you visualize the black pixels as the meaningful content, it's usually straightforward to see where things are out of balance.

98/100. "Toronto" and "Xylophone" were really hard for me. I arranged them and tried to squint from afar to make sure they looked balanced.

Xylophone was the one for me where negative space was most helpful; notice how most of the letterforms are bordered by a straight edge on one side and a curved one, always at x-height, on the other.

I liked this, although I felt a little bit of resentment over the fact that the "correct" answer is a typographer's solution -- as if no other typographer could possibly disagree.

It does allow for a certain margin of error, though:

Hmm. Crashes Firefox 25.0.1 instantly on OSX 10.6.8

Works perfectly for me on Firefox 25 on Linux. Worked fine in Nightly on Linux as well. Is something wrong with your profile?

Same for me (10.7.5). I just cracked open Chrome to try it out and no issues.

84/100 after switching to safari. I am irked that the last character in the word is not moveable as I thought many of these were too widely spaced for my tastes. I got several 100/100 scores but one 45/100 with which I utterly disagree and about which I am conferring with my lawyer.

I hope everyone filled out and submitted detailed crash reports?

Ditto Firefox 25.0.1 on OSX 10.8.5

I really like the idea behind this side. It neatly shows the difference between proper and improper kerning. It also showed me that I am much more likely to kern certain types correctly naturally.

87/100. Very interesting game, it definitely helped me start to understand why some people get so upset about incorrect kerning. Would have been nice to see a running total score throughout.

Aw man. I only got 87/100. And I thought I was a decent kemer!

Only 79/100, but I think the scoring is a bit off---it seems to judge the total divergence, when it really ought to look at each pair of letters separately.

95/100. I thought the second-to-last was hardest. Serif/sans-serif didn't make as much of a difference as I expected.

93/100. The one with small caps was tricky -- small caps fonts generally have wider letterspacing, which threw me off for a bit.

90/100, and I agree with jawns that it should be agreed upon by multiple typographers, not just one.

This is very, very pleasing visually.

Especially the compared results. I found the cyan over made some almost beautiful logotype designs over my errors.

This game doesn't work like kerning works. The game lets you re-space letters between letters at fixed positions on the left and right. Kerning is about the spacing of all letters.

> Kerning is about the spacing of all letters.

That's tracking (also called letter-spacing). Kerning is indeed about the adjustment of space between individual letters.
