From Taiko no Tatsujin 7 onwards, the Taiko Dojo mobile service was added, increasing the fun factor and providing a sense of achievement by rewarding arcade performance even further. The service is free, of course, and open to anyone in Japan with a mobile internet service and the ability to scan QR codes. After a normal play on the arcade games (and right before the Game Over screen), this is displayed if you hit the rims once (nothing needs to be hit from Taiko 10 onwards)
