Money Puzzle Exchanger / Money Idol Exchanger

MPE combines the gameplay mechanics of the Magical Drop games with some lightning-fast coin-counting addition--call it "Mathical Drop." Instead of bubbles, MPE players (most of whom are presented as schoolchildren in pastel-colored fantasy costumes) stack coins that combine to make higher denominations--five 1 coins will turn into a single 5, two 5's become a 10, five 10's turn into 50 and so forth, on up to 500 (two of those will disappear completely). One-player games offer either solo endurance rounds or matches against a ladder of CPU opponents, but as with MD, it's the two-player mode that makes the game the most fun.
