Hi folks,
I found this online quiz last night. You have seven minutes to recall and enter the names of 37 standard yaku and yakuman. The categories and han values are provided as an aid.
Click the green bar to start the timer and type the names in the box that appears there. You can use Japanese names rendered into English characters or (I've just realised!) English names.

Afterwards you can view the results to see what percentage of users were able to recall (and spell) each one - click the "view the most missed" link.
In trying to find that test again today I found a slightly different one on the same site.
The format is quite similar but this time it gives you the English yaku/man names and you have to enter the Japanese.

They're reasonably sophisticated at recognising names with/without spaces and alternate names but a couple of the spellings are a little off and that second one is a bit inconsistent with the representation of oo/ou/o.
