Right now DMM is handing out 500 points for free. So if you're interested, follow these steps:

1. Access this page with an Android device of your choice.

2. Click on "今すぐアプリをダウンロード！" to download the "DMM Game Store" Android app.

Or just download it from here and copy it onto your phone/tablet.

3. Install the app and start it up.

4. Click on the silhouette at the top-right of the screen, between the speech bubble and grid icon.

5. Click on ログイン ("Login"), then log in.

6. With your app log-in registered at DMM, wait until the 5th October. DMM will distribute the points on that day by sending a point code to the email address you've registered to your DMM account.

Don't worry if you don't get the email right away, DMM said that it might take some time.

The points are valid until the 19th October, 23:59, after which they expire.

Note: I take no responsibility for getting some or all the details wrong, so don't bother shitting on me.
