What's New

1. The theme color which was indigo will be changed into red tone to give users brighter impression.

2. Free credit reward menu will be added to give credit for free to users.

3. It will be indicated the weather and day&night of the opponent in the 1:1 chatting room. Please note that the current wallpapers customized for each chatting room would be reset due to this update.

4. The OTO number and SMS messaging service will be terminated with this update. (Further notice will be made with this change.)

5. As Google announced their plan to stop offering the consumer version of Google+ , Google+ log-in service will be replaced by Google log-in. (Former users can use as well.)
