I am having problems signing into Google Play Games Service (Android devices only)

Please try the following:

1. Fully exit from Bushido Bear as described here: https://spryfox.zendesk.com/hc/en-us/articles/218505778
2. Launch Bushido Bear.
3. Open the Options menu (from the main menu, click the gear icon in the upper-left corner).
4. Look for the button with a controller icon. If it says "Signed out", click it to sign in.
