Coin/LINE

Coin is the main and the most common currency in Cookie Run. It can be obtained freely and indefinitely, from many different methods. Coins allows the player to buy cookies, boosts, Power Upgrades and upgrade owned cookies, pets, or treasures.

Types of Coins
There are five types of coins.

Silver Coins are worth 1 coin, and are the most commonly seen coin. As the name states, the coin are colored silver and can be obtained while playing or appears with unique patterns in Bonus Time. Some pets also produces silver coins, such as Hat of Santa also generates 5 silver coins one at a time or Pirate's Bomb which turn obstacles into coins. "Coins Jelly" will also turn obstacles into coins.

Gold Coins are worth 10 coins, and appears less common. They are golden and slightly bigger than Silver Coins, hence the name. This coin often appears either before or after the energy potion, and sometimes forming "LUCKY!" or a heart with an arrow. Gold coins also appears in narrow spaces in several stages. They also can be obtained with the Random Boost item 'Gold Coins boost' which makes Coins Jelly and Pirate's Bomb turn obstacles into gold coins. They are also available in any variation of Bonus Time.

Giant Gold Coins are worth 100 coins. As the name implies, these coins are Gold Coins, just much bigger and worth 10 times as much. In season 1 of Cookie Run, only Gold Drop can produce this kind of coins, but in season 2 this coin appears more often. This coin sometime appears in the narrow spaces in the game (such as in the Stage 4), and sometimes also appear above the Energy Potion. In bonus time, this cookie will be much more often appears in the bear-jelly-themed Bonus Time, although this coin also found in space-themed Bonus Time.

Cat Coin is only produced by Fluffy Cheese Cat pet. The pet will occasionally generate a coin with a cat face inside the coin's surface and worth 20 coins. However, cat coin cannot be obtained from any other method and will not appear randomly in certain stages.

The newest addition on Season 4 is Flying Coin, which can only be found at the 7th stage of Dragon's Valley. It is worth 20 coins, and like other flying jellies, it is unaffected by the pull of Magnetic Aura. This coin is not recommended for coin farming since it takes a long time and effort (Cookie Relay and Energy Drain 25% Slower) just to reach that stage with the flying coin.

Each coins obtained by the cookie in the game (not from treasures/bonuses) gives points too. It is relatively gives smaller points than jellies, but may also contributes some portion to the overall score.

Earning Coins
Coins can be earned by many ways.

Playing games
Any types of coins can float in mid-air and can be collected by making pets going to the coins (or using magnetic aura to attract coins from narrow spaces or from distance closer to the cookie). They also are available in Bonus Time. At the end of the game, some boosts, cookies, pets, and treasures will give extra coins added into the coin bonus total based on the coins originally collected during the game. The coin bonuses stacks, so if there are more than one coin bonus effect, the cumulative coin bonus will gets bigger. For example, when a player earns 1,000 coins at the end of the game, and there are two bonuses 25% and 10% each, the final coins earned will be 1,375 coins (1,000 x 125% = 1,250 x 110% = 1,375) not 1,350 coins (1,000 x 135%).

Coin Farming
Coin Farming is a term many players used to refer the most effective way to earn coins while playing games. There are several methods of earning coins quickly. The objective of coin farming is to either earn big amount of coins in relatively short run or earning the biggest possible amount of coins in a long run, using combination of unique set of cookie, pet, treasures, and boost.

Lucky Draw
For every 100 Gift Points earned, players gets a chance to take a Lucky Draw that will gives coins or other prizes. Coin amounts are ranging from 1,000~3,500 (with 500 coins in increment), and more rarely 5,000 and 10,000 coins.

Selling Treasures and Ingredients
Players can sell unwanted treasures and ingredients either to free up space or because the treasure are subjectively judged by the player to be less useful or not needed. Some players usually also sells treasures from upgrading a lower-grade cookie or pet to Level 8, however after selling the treasure, in order to earn the treasure again the player needs to buy with Crystal.

Buying with Crystals
When in need, players can purchase more coins with Crystals they own. Players in the main window of the game can tap the Coin bar and a Coin Shop will pop-up offering coins with five different price pack. However, most users does not buy coins this way unless they needs more coins urgently.

Complete Achievements
Achievements are present in each Episode from Season 4. They are used as a reward for every user to gain additional coins once they complete these achievements. The more achievements completed, the harder the achievements will be.
