Ai trả Tiền?

Ai trả Tiền? is a multi-touch party game that randomly chooses who pays the bill

Ai trả Tiền? turns the awkward question of “who’s paying?” into a fast, funny, and dramatic party moment.

When your group goes out to eat, grab coffee, or hang out together, there is no need for long discussions about splitting the bill. Everyone simply places one finger on the same phone screen. After a few suspenseful seconds of heartbeat sound effects and dark red visual effects, the app randomly selects one person to pay everything or take the heavier share.

The most unique part of Ai trả Tiền? is the multi-touch experience on one device. Everyone joins at the same time, everyone waits together, and everyone reacts when the red beam locks onto one finger. It is designed as a social entertainment app for dinners, parties, trips, and group moments where you want a quick and playful decision.

Main features:

- Real multi-touch gameplay on a single screen
- Suspense countdown with heartbeat audio
- Dramatic red beam reveal effect
- `All In` mode: one person pays the full bill
- `Pay More` mode: one person pays a larger custom percentage
- Optional bill input to calculate the exact amount each person should pay
- Fast setup with no login and no account required
- Dark, high-contrast party-style interface built for immediate impact

Ai trả Tiền? does not process real payments, does not store wallets or cards, and is not a gambling app. The result is random and intended purely for entertainment and group interaction.
