CHALLENGE|You can send your highest score to other players in the Challenge Note menu. A Challenge Note is sent via SMS text message and its record is saved on the server. The score of the received Challenge Note will be displayed on the screen during game play and bonus points will be added once you score higher than the received challenge. You can send Challenge Notes to phone numbers and game IDs. Challenge Note should be downloaded from the server within 7 days from the reception day otherwise it will be automatically dropped (deleted) from the server. You can gain 1 challenge point each time you send or receive the challenge note. If you receive a received note above or under your score, you will get 20 challenge points for above and 1 challenge point for the lower.
