Coin Exchanger is a brain puzzle game where you can enjoy chain combos and 1:1 battles with simple controls. Place coins, build your score, and enjoy quick matches with friends.

■ A Puzzle Game That Gets Deeper the More You Think
Pick up coins stacked at the bottom and move them to the column you want. When matching coins connect horizontally or vertically, they are exchanged for higher-value coins. The rules are easy, but planning big chains brings out the deeper fun of the puzzle.

■ Basic Rules
· Move the character at the bottom of the screen left and right.
· Pick up a coin from the lowest row with [Grab], then place it with [Throw].
· Matching coins exchange into a higher coin.
· 1, 10, and 100 coins exchange when 5 of the same kind connect. 5, 50, and 500 coins exchange when 2 of the same kind connect.
· Two 500 coins disappear from the board.
· Consecutive exchanges create chain combos and greatly increase your score.
· The game ends when coins pass the warning line.

■ Special Coins
Sometimes green RU coins and blue ER coins fall with regular coins. Connect two special coins of the same type to trigger a powerful effect. RU upgrades the target coin, while ER removes all matching target coins from the board. Use them to escape danger or prepare a big chain.

■ 1:1 Battle with Friends
Create a room and share the code, or join your friend's room with a code. When both players are ready, the game starts after a 3-2-1 countdown. Both players receive the same coin sequence. Create chains of 2 or more to send obstacle lines to your opponent. The first player to cross the warning line loses.

■ Rankings and Records
Your top 5 high scores are saved. If you log in, you can keep using your records and points across devices.

■ Controls
On mobile, use the buttons at the bottom of the screen. One-handed controls are available in the options. On a PC browser, use the arrow keys and Z(Grab) · X(Throw).
