I vs I

"I vs I" is a limited time event in Cookie Run. The event will require the player to break their own new all-time high score for Crystal reward. Usually, "I vs I" event will occur every between two or four months, in an irregular cycle with other events.

Rules

 * 1) The player need to beat their own new all-time high score anytime during the period (not the weekly leaderboard score).
 * 2) In Escape from the Oven, Primeval Jungle, and Dragon's Valley, reward will be given for high scores above 500,000 points.
 * 3) In Ghost Pirate's Island of Coins, reward will be given for high score collecting at least 1,000 coins.
 * 4) Reward can only be earned once during the event.

I vs I event returned in Cookie Run: New World.

Although it is still the same as the previous seasons, players are challenged to defeat their own all-time high scores in all four episodes available to play. Defeating your own all-time high score (or above 500,000 for first-time players) will reward the player 15 each episode. Defeating all high scores in all four episodes will grant the player a total of 60.

This is one of the first occurrence when Ghost Pirate's Island of Coins is included in the event (where usually most events ignored this episode). Any first-time players must set high scores above 1,000 in order to get 15.

In addition to keep track on which episodes' high scores have not been obtained yet, a bubble will show you which episodes that you have not reached yet on the Episode Map.

This seventh I vs I event is similar to the previous event.

October 2-15, 2015
The eighth event comes with some notable differences:
 * Each score beaten will grant the player 12 instead of 15.
 * There are five scores to beat instead of four.
 * New players are requested to earn 1,000,000 points to get the Crystal reward instead of 500,000.
 * In all episodes except Ghost Pirate's Island of Coins, players will receive the reward if the player reaches 300 million points regardless if the score actually didn't reach the all-time high score.
 * A phrase "The Last!" appears at the top of newsletter. Many players have speculated about the actual meaning of the phrase.
