The daily check-in awards the player 500 Coins, and 1000 Coins on every 10th check-in.
Clearing a Main Stage for the first time will earn the player 100 Coins, and any subsequent clears will earn 30 Coins (20 Coins in Mobile). An Expert Stage cleared for the first time earns the player 300 Coins, and most Special Stages award 200 Coins upon the first clear.
The maximum number of Coins a player can have is 99999. The counter will cap at that number and any more Coins the player gains will be lost. The Shop will prevent any Coin purchases that would bring the counter over the cap. On the Mobile version, any Coin Gifts that would bring the counter over the cap cannot be claimed, and will instead be retained for future use.
Coins can appear on some stages as disruptions. They can be matched and removed from the board in the same way that Pokémon can, but instead of yielding points the player will instead earn extra Coins after clearing the stage. Matches of 3/4/5/6 earns the player extra 100/300/500/700 Coins. Matched Coins will only be kept if the stage is won.
The Swap (+, ++) abilities can transform a Coin into another icon. Stabilize (+, ++) can remove Coins from the board. Rocks and Blocks can transform into a Coin through the Prospector and Alchemist abilities; however these abilities are not currently accessible in the game by any legitimate means.
