All Friends give bonus points when blocks of the same shape as they are removed.

Certain Friends periodically generate Hearts, Gems, and Moves +2 items, or have a skill that creates a chance of generating Gold Ryans, Sunglasses, Hats, or Sunglasses and Hats blocks at the beginning of a game. 

For more information, please refer to each Friend's page. 

While playing up to Chapter 2 (24 levels), you can collect the Classic Friends Set.

After Chapter 2, you can get Friends with various features through the Gacha System. 

You can use the Gacha with Gems and Cons as well as Lucky Gacha Keys, which you can get as Event/Friend Level-up rewards. 

You can also get limited edition Friends by clearing the Gold Bonus level for each chapter.

You can level up your Friends by increasing their EXP during games or using Friends of the same kind that you found through Gacha. 

Every time a Friend reaches a new Level, their point bonus and skill improve, and they also randomly generate Cons, Hearts, Lucky Gacha Keys, Gems, and other rewards. 

You can collect your Level-up rewards in the Game Results screen or on the My Friends page. 

Collect all 8 Friends of the same kind in the Friends Collection Book, and you will get Gems or a set Friend as a Set Completion reward. 

Also, equip a set of 8 Friends in the Collection Book, and they will periodically generate Hearts and Set Chances.

Generated Set Chances can be used anytime during games to instantly add a set number of moves.

On the My Friends page, tap the Replace Friend button at the bottom of the screen to equip a different Friend. 

Note that if the Friend being replaced has a periodic production skill, then its production time will be reset. 

You can select and change your Leader Friend among the Friends that you are equipped with.

On the My Friends page, select the Friend you want and tap the Leader button to make it your Leader.
