šŸŽ® Gameplay
How do I win a match?ā–¼
Complete 5 full lines on your number board ā€” a line is any row, column, or diagonal where all 5 cells have been marked. The first player to reach 5 lines wins. This is called the "Gangu."
How does the filling phase work?ā–¼
Before the match begins, each player fills their grid with numbers 1 through NĀ² (for a 5Ɨ5 board, that's 1ā€“25). You can let the app auto-fill, or use the Manual Grid Fill feature to place numbers exactly where you want them for a strategic setup.
How does number calling work?ā–¼
Players take turns calling a number. When a number is called, it is marked on every player's board where it appears. You choose which number to call on your turn ā€” you have 15 seconds to make your call before your turn passes automatically.
What are AI Move and Extend Time?ā–¼
AI Move lets GanguBot pick the optimal number to call on your behalf for a single turn ā€” useful when you're unsure which number gives you the best line progress. Extend Time adds extra seconds to your current turn timer. Both are consumable items purchased with Babi coins from the Supply Store.
What is the Spy feature?ā–¼
Spy lets you view your opponent's board for a brief window ā€” giving you information to call numbers that hurt their progress while helping yours. The Anti-Spy feature (Premium only) blocks opponents from using Spy on your board.
What grid sizes are available?ā–¼
GanguGu supports 5Ɨ5, 6Ɨ6, and 7Ɨ7 grid sizes. Larger grids mean more numbers, longer matches, and more complex strategy. The default and most popular size is 5Ɨ5.
šŸŒ Multiplayer
What's the difference between Local LAN and Online Game?ā–¼
Local LAN connects players on the same Wi-Fi network ā€” great for playing with someone nearby. Online Game uses our WebSocket server to match you with players anywhere in the world. Both use the same Create Room / Join Room flow.
I lost my internet connection during a match. Can I rejoin?ā–¼
Yes. If your connection drops, the game attempts to reconnect for 30 seconds. Tap "Rejoin Game" on the home screen overlay to return to your active match with your board progress fully intact.
How does real-time matchmaking work?ā–¼
When you select Quick Match, the app connects to our Node.js WebSocket server and pairs you with another available player. Handshakes complete in under 500ms for a smooth, zero-delay match start.
šŸ’° Purchases & Coins
I paid for a coin pack but haven't received my coins. What do I do?ā–¼
All transactions are verified by our PostgreSQL backend before rewards are issued. For cryptocurrency purchases via NOWPayments, delivery depends on blockchain confirmation time ā€” typically 2ā€“10 minutes. If your balance hasn't updated within 15 minutes, email contact@gangugu.games with your order ID.
How do I restore my purchases on a new device?ā–¼
Sign in with the same Firebase account (Google or Email) you used originally. Your Babi coin balance, Premium status, achievements, and unlocked themes will sync automatically to the new device.
What does Premium include?ā–¼
Premium permanently removes all banner and interstitial ads, grants an exclusive Premium badge on your profile, unlocks Premium-only themes and grid skins (like Cyber City, Royal Gold, Indigo Gold), and enables the Anti-Spy feature to protect your board from opponents.
šŸ“ŗ Ads & Rewards
I watched a rewarded ad but didn't receive my +100 coins. What should I do?ā–¼
Ad reward callbacks can occasionally delay. Make sure you watched the video to completion until the Close button appeared. If coins are still missing after the ad ends, restart the app ā€” this forces a sync with our backend and should credit the reward.
Do ads appear during gameplay?ā–¼
No. Our ad mediation (Unity LevelPlay) is configured so that no ads ever interrupt an active match. Ads only appear between matches or on specific screens. Upgrading to Premium removes all ads entirely.
