Money Idol Exchanger (also known as Money Puzzle Exchanger in the US) is a puzzle game created in 1997 by Japanese video game developer Face for the Neo-Geo MVS arcade system. Athena Co. Ltd. ported it to the Game Boy and the PlayStation that same year.

Money Idol Exchanger is a stacking game similar to the Magical Drop, Astro Pop, Moujya and Puzzle Bobble series whereby players race to prevent a perpetually falling array of coins in different values from filling up the screen. Coins are combined (vertically and/or horizontally) to form higher valued coins; for example, five '1' coins will form a '5' coin, and two '5' coins will form a '10' coin, and so on, until two '500' coins are put together, at which point both disappear. Coins are arranged and colored to match denominations of the yen specie. Two bonus tiles allow for changes in gameplay. A green RU tile will rank up all coins of the same denomination; for example, all '10' coins will become '50' coins. A blue ER title will erase all coins of the same value. The game is won when any coin reaches the bottom of the opponent's screen.

In the single player mode, you control one of two characters who attempt to beat up to seven idiosyncratically named characters with names like Debtmiser, Mightdealer, Eldylabor, and Cherrybeiter. In the two player mode, both players fight each other until victory. The quicker and more efficiently each player clears out their screen, the quicker the other player's screen will fill up. Since filled screens offer the most opportunity for chaining together large combos, the tide can turn very quickly.
