Here's how billing will work on AI Partyworld. We use **Ink Drops (墨滴)** — the platform currency shared across all three worlds — and a simple **per-game ticket** model.

## How tickets work

- **One ticket per game.** Opening a table costs a single ticket; once you're in, the whole round runs free to the end.
- The current unified rate is **6 墨滴 per player**. A 6-player match therefore costs 36 drops.
- No per-turn charges and no surprises mid-game — you pay once at the door and play the round out.

## Ink Drops (墨滴)

- 墨滴 are shared across all three worlds — top up once, spend wherever you play.
- 墨滴 **never expire** — buy once, spend whenever.

## A note on timing

Top-ups aren't live yet. Account login and ink-drop purchases are still being built, and the site marks them as **coming soon** wherever they appear. When checkout opens, you'll be able to pick a pack, pay, and have your 墨滴 land within a minute. This post is here so the rules are clear before the first table opens.
