Krystal Drop project is a free clone of NeoGeo's Magical Drop.

In it, you play on a field on which lines of gems are being dropped by the top of the screen, at a regular basis or when your opponent makes a combo. You can take or drop gems from the bottom of the screen to make gems disappear.

If you move gems in order to create a vertical alignment of at least three gems of the same colour, they will burst and start a chain reaction with all neighbouring matching gems.

The aim is to prepare some other chain reactions while the first gems are bursting, in order to make a combo and send lines to your opponent. You lose when some gems reach the bottom of the field.
