# Auction House and coinflip

Trade items between players, flip coins and play roulette.

Both have an NPC with a hologram at the spawn.

## Auction House

* **Sell:** hold an item and type `/ah sell <price>`.
* **Buy:** open `/ah`, sort the listings and click an item to buy it.
* Listings last **48 hours**. A **5%** listing tax is paid when you list, and refunded if the listing is cancelled or expires.
* Expired, cancelled and bought items that do not fit in your inventory wait in the **Claim Items** menu.
* Listing limits by rank: Member 3, VIP 5, Elite 7, Legend 10, Ultimate 15.
* Bedrock players get native forms.

Edit it in `plugins/AuctionHouse/config.yml` (tax, duration, limits per LuckPerms group, menu slots) and `messages.yml`.

## Coinflip and roulette

Open the casino with `/cfz`.

* **Coin flip:** create a game with a bet from ⛁10 to ⛁5,000 and wait for another player to join. 50/50 chance to win both bets. One new game every 60 seconds per player.
* **Roulette:** bet on a number, red or black, even or odd, low or high, a dozen or a column, then spin.
* The house keeps **5%** of each bet.
* Personal stats and a top players list.

Edit it in `plugins/CoinFlipZ/config.yml` (bets, payouts, house edge) and `messages.yml`.
