Description by Duong Trieu Nguyen Van(from the App Store)
Quadigit is a bite-sized logic puzzle game about one simple goal: find the 4-digit code and unlock the next door.
Each door gives you a clue. Sometimes the answer is hidden in words, symbols, patterns, animations, device states, or the way you interact with the screen. Look closely, think sideways, and enter the code when it clicks.
Features: • 4-digit code puzzles built for quick play sessions • Different puzzle styles: logic clues, ciphers, visual tricks, animations, and interactive reveals • Hints when you get stuck • Skips for difficult doors • Progress saved on your device • English and Vietnamese language support • Neon-inspired visual style
Quadigit is designed for players who enjoy clever riddles, hidden patterns, and “aha!” moments. Some doors are obvious. Some are strange. Some want you to stop thinking normally for a second.
