Viral

TikTok made this category — content IS the distribution

01 / HOW IT WORKS

What the app actually does

The game mechanic is one of the simplest in mobile gaming — the entire app is built around one clean rule that takes 10 seconds to explain.

Everyone in the group opens the app on their phone

Multiplayer without a server — phones act as the "deck" of cards, no real-time connection needed between devices.

All players receive the same secret word — except one or more Impostors

The Imposter doesn't know the word but has to pretend they do without getting caught.

Players take turns saying one thing related to the word, without saying it

The Imposter has to bluff based on context clues from the other players' hints.

Group votes on who they think the Imposter is

Rounds are short (3-5 minutes), making it perfectly suited for content — people film the reveals constantly.

02 / INDIA POTENTIAL

Does this work as an India play

Indian party gaming apps are almost non-existent — Ludo King has the market but it's strategy, not social word games. The WhatsApp group-based party culture in India is a perfect distribution channel.

Direct Indian competitors in the social word-guessing party game niche — wide open category.

Indian friend groups coordinate socially through WhatsApp — a "share to your group" flow is the viral mechanism.

Hinglish

A word pack in Hindi/Hinglish specifically for Indian pop culture references, Bollywood, cricket, desi food.

₹99

One-time IAP to unlock additional word packs — the lowest-friction monetization for Indian users.

03 / THE WEEKEND BUILD

Friday to Sunday, hour by hour

This is one of the fastest possible builds — the core mechanic is just display a word to some players, hide it from one. No backend, no real-time database needed for the basic version.

Friday

Evening · 3 hrs

7–8 PM Set up a React Native (Expo) project — cross-platform, single codebase for iOS and Android.

8–9 PM Build the player setup screen — enter number of players, optionally enter names, pick a category.

9–10 PM Build the word reveal flow — each player taps their phone to see their word (or "You are the Imposter!").

Saturday

Full day · 7 hrs

Morning Build the discussion timer and vote screen — countdown timer, then everyone submits who they think the Imposter is.

Afternoon Build the reveal screen — show who was the Imposter and whether the group guessed right.

Evening Build 5 word packs: General, Bollywood, Cricket, Food, and Desi Memes — 50+ words each.

Sunday

5 hrs

Morning Add a share screen — auto-generates a shareable image/text of the result perfect for WhatsApp sharing.

Afternoon Implement Razorpay for a Rs99 one-time IAP to unlock 3 additional premium word packs.

Evening Submit to both App Store and Play Store, record the demo for your first reel.

04 / APP STACK

What you're actually building with

React Native (Expo)

App framework

Single codebase for iOS and Android — no backend or server needed for the core game.

Local state only

Game logic

The entire game runs on-device — no Firebase or Supabase needed for the core loop.

Word packs (JSON)

Content

Hardcoded JSON files for each category — simple to add new packs without an app update.

Razorpay

Payments

Rs99 one-time in-app purchase for premium word packs.

Share API

Virality

Native share sheet for WhatsApp/Instagram sharing of round results.

Expo EAS Build

Build + deployment

Handles app store submission without native Xcode/Android Studio complexity.

05 / WHERE & HOW TO DEPLOY

Going live

Where: App Store and Play Store — mobile-only app, no web hosting needed. Use Expo EAS Build for a managed build process. App Store review: 1-3 days, Play Store: 1-7 days.

Create an Expo account and set up EAS Build — eas build --platform all builds iOS and Android at once.

Submit the Play Store build first — review is typically faster.

Submit to the App Store via App Store Connect — you need an Apple Developer account at $99/year.

While reviews process, set up Razorpay in-app purchase and test on a device.

Record your first demo reel before the app is live so you are ready to post the moment it is approved.

06 / MARKETING & REVENUE

Getting paying users

How to market it

Film the actual reaction of friends playing — the confusion, the bluffing, the IT WAS YOU reveal moment is the content itself.
Run 10-20 reels/day across multiple accounts of different people playing the game — content IS the distribution.
Share to WhatsApp groups directly — the game is designed for friend groups, so the natural share drives organic installs.
Build a Hinglish word pack with culturally specific Indian references — something global games do not have.
The original Imposter grew its Instagram to 10K followers and 50M TikTok views in 30 days organically.

Who pays, and why

Friend groups looking for party games that need no equipment and work on any number of phones.
Indian families at gatherings and festivals where group games are a tradition.
Content creators who make reaction/prank content and want a built-in game mechanic to film.

BUILD_PROMPT.txt

I want to build an Indian party word-guessing game app, inspired by the Imposter game that went viral with 50M+ TikTok views, scoped to ship in a single weekend. Core mechanic: 1. All players open the app on their phones and set up a game (number of players, word category). 2. Each player taps to see their word — except one or more Impostors who see "You are the Imposter!" instead. 3. Players take turns saying one hint related to the word without saying it — Impostors must bluff. 4. A discussion timer counts down, then everyone votes on who they think the Imposter is. 5. Reveal screen shows who was right and who the Imposter was. 6. A share feature generates a shareable result card for WhatsApp/Instagram. Word packs: General, Bollywood, Cricket, Desi Food, Hinglish Memes. Rs99 one-time IAP unlocks 3 additional premium packs. Stack: React Native with Expo, entirely local/on-device state (no backend), Razorpay for IAP, Expo EAS Build for app stores. Help me step by step: 1. Scope the Expo project structure and data model for word packs, players, and game state. 2. Build player setup and category selection. 3. Build the word reveal flow. 4. Build the timer, vote, and reveal screens. 5. Build the WhatsApp share card. 6. Implement the Razorpay IAP. 7. Walk me through Expo EAS Build and submitting to both stores. Keep explanations short and India-context aware. Optimize for the WhatsApp sharing flow. Push me to ship the smallest working version first. If I get stuck, tell me to ask @buildwithkanhaa.
