☕ Delicious Win — Who's buying coffee today?

Delicious Win is a collection of party games for friends and coworkers in the same place, each playing on their own phone, to decide who pays for coffee or lunch. One person creates a room and everyone else joins by scanning the room QR with their phone camera. No app install, no sign-up. Last place is on ☕ coffee duty!

The app opens in Korean by default — switch to English in the ⚙️ settings menu at the top right.

How to start

  1. Create a room: one person (the host) enters a name and taps [Create a room].
  2. Add players: the host taps ＋ to show the room QR. Players scan it with their phone camera and tap [Request to join]; once the host allows it, they're in. You can also invite with a link.
  3. Pick a game: in the lobby, the host picks a game, sets the rules and taps start.
  4. Results: when the game ends, the coffee buyer is announced. Play again with the same players, or pick another game!

Want to try it alone first? Tap [Practice solo] with no other players (all four games, against the dealer or bots). No internet? Connect everyone to the host phone's hotspot and join with "scan each other's QR".

Game rules

🃏 Blackjack

2–8 players · 3–5 min · fewest chips buys

Everyone starts with the same chips and plays against the dealer at the same time. Get as close to 21 as you can without going over. When the last round ends, whoever has the fewest chips buys the ☕. Tied? One sudden-death hand decides it. The host sets the number of decks, rounds and starting chips.

📈 Day Trading King

2–8 players · 1–2 min · worst return buys

Everyone starts with ₩1,000,000 in seed money. Once the market opens, prices move every second and breaking news pops up now and then — but prices start moving 1–2 seconds before the headline, as if it leaked, so reading the chart first pays off. Buy and sell 25% / 50% / all of your cash or shares; whoever has the lowest portfolio value at the close buys the ☕!

🔮 Pinball Roulette

2–8 players · 1–2 min · last marble buys

Everyone drops in a marble and they all roll together. Whoever owns the last marble to arrive buys the ☕. Mid-race, shake things up with 🌀 Spin the windmills (2×) and 🧊 Freeze the leader (1×). Maps: 🎡 Ferris Wheels, 🫧 Bubbles, 🍯 Honey Jar, 🪜 Zigzag. Every phone shows the same race, and each phone verifies the result itself so nobody can rig it.

🃏 Rummi Cards

2–4 players · 15–30 min · most points left in hand buys

A rummy game with two standard decks plus 2 jokers. Lay down sets of 3 or more: the same number in different suits (group) or consecutive numbers in one suit (run). You can split and rearrange sets on the table. Your first play must total 30+ points. The round ends when someone empties their hand — whoever has the most points left buys the ☕!

FAQ

Really no install?

Yes. It opens right in your phone's browser. Add it to your home screen to use it like an app; once opened, it even works without internet.

How many players?

Up to 8 per room, including the host. Each game has its own range (Rummi Cards: 2–4).

Is real money involved?

No. Chips and money in the games are just scores — it's a fun way to decide who buys the coffee.

Are game records stored on a server?

No. Phones talk to each other directly over an encrypted connection, and no game records are kept on the operator's servers. See the Privacy Policy.
