DropMix is a music mixing game developed by Harmonix and published by Hasbro, launched in 2017 but discontinued.

The game used physical cards with chips embedded with near field communication, a specialized electronic game board with NFC and Bluetooth capabilities, and a companion application for mobile devices (iOS or Android) that communicates with the board via Bluetooth.

By playing a card, representing a specific song, atop a proper board space, the board will detect its NFC code and relay that to the app, which will play a sample from that song, such as a drum loop or a vocal section.

Placing a card on a space with a matching color will cause that track sample to be used as part of the app's current mix; non-matching placement will have no effect.

In the app, this represents how much an influence the sample will have on the ongoing mix in terms of its speed, key or length.

Special white cards can be played on any space, which can cause an entire change in the speed and key of the ongoing loop.

[2] "Freestyle" mode lets players simply try to combine the cards in various mixes without any other rules or scoring goals.

In "Party" mode, one to five players split the available cards between them, and taking turns, must try to respond to specific "requests" provided by the app in the fastest time, with score penalties if they play incorrectly.
