Here's a little game inspired by a previous thread.

http://vps.isoron.org/japanese/haga/

How to play:

1. Paste a Japanese text into the box, then click start
2. Each が/は will be replaced with a red asterisk ＊
3. Try to guess which particle is hidden behind each asterisk
4. Click the asterisk to reveal the answer

Hope you enjoy it.

You're a good person. I like you!

This'll be fun to pass around to friends.

I'm very impressed by your web developer + 日本語 programming prowess.

What's the server-side code done in? Would you mind sharing the code? (I've long wanted to get a handle on mecab, and your は×が game looks like a perfect vehicle for it.)

Looks great!

This is an amazing tool. Lot's of fun to use, interactive, instant feedback.

Thank you for your hard work

Any way you can integrate this (or make it work with) Anki? Would be a great way to get a really good handle on は and が in even the most tricky of linguistic situations

That's awesome!! Thanks so much

Can't wait to use this !

It's an old-school CGI script: bash, sed, awk. Not very beautiful.
I'll rewrite it in Ruby or Python, then post the code.

It's certainly possible, the needed technologies [mecab+javascript] are available there; but how exactly would you use it? Hide the particles in the question field, try to guess everything, then grade? Seems to go against the minimum information principle? Aren't multiple cards better than a single very complex one?

I think this is an exception to that rule because は and が are so contextual.

Then again, what do I know, I haven't even started SRSing sentences yet.

Lots of the time they appear several times in a short space of time so when u have a card that's testing you on a couple (i'd say 3 - 4 max) then I guess the idea is to get a natural grasp of は and が in settings where you have to explain things longer than パンが食べたい。

Perhaps what I mean is having a function where you can save to a list to import into Anki later. So you could be using the page lots for practice and then if there's something you trip up on and want to put it into Anki for practice or a reminder then you have an easy seamless way to do it. Or something to that effect.

I wonder if it would be possible to make something similar for kanji production practice.
What I mean is that several kanji in the text disappear and hiragana (katakana) appear instead and you have to figure out the correct kanji. That would be awesome production practice (practice for Kanken), but I have no idea if it's too difficult to program s.th. like that.
