Six ways to play. One goal: crack the code. From a quick daily challenge to live 1v1 duels — there's a mode for every agent. Daily Operation A new code every day, the same for every player worldwide. Compete on the global leaderboard and compare your performance. 1 challenge / day Against the Clock 120 seconds on the clock. Crack as many codes as possible before time runs out — every second counts in the global rankings. Infinite Loop No time limit. Keep cracking codes and build your longest streak ever. How far can you go? 1v1 Duel Generate a challenge code and send it to a friend. Both crack the same code , whoever uses fewer attempts and time wins. Async friend duel Online Match Get matched against a random opponent in real time. No friends needed — just your wits. A bot steps in if no one is available. Live ranked match and much more. How to Play Simple rules. 1. The Secret Code A random 4-digit code is generated. No repeating digits. The first digit is never 0. 2. Make a Guess Enter your 4-digit guess. You have 10 attempts to crack the code. 3. Read the Feedback + = correct digit in the right position. − = correct digit, wrong position. 4. Use Power-ups You can reveals a hidden digit. Or hit to button to grant 1 extra attempt. Both require watching a short ad.

■ It looks like a terminal. That's the point. Black screen. Neon green text. System logs scrolling forever. CPU load and memory pressure climbing. To anyone glancing over your shoulder on the train, you are debugging a complex production system. What you are actually doing is connecting three or more matching symbols. ■ How it plays You are an incident response engineer covering 16 data centers around the world. - Pick a degraded node on the world map - Travel there (the farther it is, the longer it takes) - Patch the bugs on site (that's the puzzle) - Earn experience and move to the next incident (credits arrive on promotion) Tokyo, Seoul, Singapore, Frankfurt, Sao Paulo, Cape Town and more. Travel time is derived from real geographic distance, so crossing the planet actually costs you time. ■ Three numbers are trying to kill you While you work, three resources keep rising: - CPU — above 72% sectors of the board freeze and become unusable - MEM — clearing five or more at once brings it down hard. Small clears barely dent it - TRACE — accelerates the higher CPU and MEM get. This is your real timer If any of them hits 100%, the session is lost. Clearing three at a time will never outrun the load. You have to build bigger COMBOs, and land them fast enough to hold the CHAIN multiplier. ■ Fatigue, and the engineer ladder Deploying and traveling makes you tired. Fatigue only recovers in real time, and going in exhausted means starting from a worse baseline. Knowing when to rest is part of the game. Patching bugs earns experience and promotions: INTERN, ENGINEER, SENIOR, STAFF, PRINCIPAL, DISTINGUISHED, FELLOW — and beyond. The final rank is SINGULARITY at level 85. Restore all 16 nodes and the world is reinfected at a higher severity. It does not end. ■ Compete monthly Register a handle and you appear on the global leaderboard — by experience earned, by best COMBO, and by incidents contained. It resets every month, so a late start is never a lost cause. Registration is optional. ■ Escalations Eight times a day, one site escalates. Containment takes three passes and the site relocates after each one. Each escalation has its own rule for what counts as progress, and the briefing tells you before you commit. ■ Languages The interface is English — it has to read as a terminal. The manual and the daily orders are also available in Japanese. It follows your device language, and you can switch it from the profile screen. ■ Made for - Short sessions with real pressure - Not wanting to look like you are playing a game in public - People who like black terminals ■ Ads and purchases Free to play all the way through. Ads are mostly opt-in — watch one to skip travel time or recover fatigue, only when you choose to. A one-time PRO license removes ads permanently.
