Dropper (nes)

DROPPER

Suck a color. Drop it. Match 4. A 60-second color puzzle — built as a real NES (Famicom) ROM.

DROPPER grew out of 125 Inc.'s puzzle research and was ported to genuine 8-bit hardware. You play it right here in the browser, and you can also download the ROM and run it on an emulator or a real console.

How to play

1. Suck – move the cursor onto a block and press the button. The dropper draws up its color.
2. Drop – move to another block and press again. That block, and every block connected to it, turns into the color you carried.
3. Match 4 – four or more connected blocks of one color pop. New blocks fall in, and if they line up again, you get a chain.

Keep popping without a break to build your COMBO. The score multiplier climbs up to ×5.00. When the 60 seconds run out, your score goes on the TOP 5 ranking, which is saved.
