# Marketplace

Hibiki Run's in-app marketplace is a common ground for traders and players to buy and sell their digital collectibles gained from the [raffle machine](/hibiki-run-whitepaper-v3.0/how-it-works/raffle-machine.md).

For **iOS users**, marketplace will be placed inside [Hibikirun.com](https://www.hibikirun.com/) (due to Apple's restrictions).
