Direct Challenges for Puzzle Battle Hits Beta

Now you can throw down vs your friends on demand. 

NOTE: You can only challenge members of beta currently. If you send a challenge to someone, not in beta they will not get the challenge. 

You can challenge up to 10 friends at once. 

Direct battles do not affect your streak and do not give you any season points. 

Known bugs: 

- Battles should be rated, but currently, are not. 

- Challenge doesn't go away if you are the second person to accept it

- After you accept a challenge, it appears that no battle with start because there is no waiting screen. 

Enjoy everyone!
