One of my favorite little exercises/challenges on Duolingo is Match Madness, where you’re presented with a column of words from the language you know, a column of words from the language you’re learning, and you’ve got a time limit to match the words from each column. Like this:

There are nine levels of this where the number of matches you must make within the time limit.

At least, I thought there were only nine levels. That was until I beat the ninth level this afternoon to reveal this:

MATCH MADNESS EXTREME!

Three more levels. I can get to level 12 but I can’t get through it yet, so who knows if there is anything beyond that.
