Zyl is a puzzle built around elegant path tracing. It's a small, quiet game. Soft colors, clean lines, and nothing on screen you don't need. Drop arrows on the grid to guide each path from its start tile to an exit. Pick up the stars on the way. When you're ready, hit Play and watch the route run. The rules: • Drag arrows onto the grid. • Send every path to an exit. • Pick up every star. • Hit Play to test the route. • Reset and try a new approach whenever. It starts simple, but then the difficulty ramps up: • Boards don't always use a clean grid. • Some levels have more than one start, or more than one exit. • Split arrows send a path off in two directions at once. • Merge arrows converge two paths into one. • U-turn arrows re-route a path from where it came. A few things worth knowing: • 300 handcrafted levels, each built around a single idea. • Levels stay small. Most of them can be finished in less than a minute. • Cloud save syncs your progress across devices. • Relaxing music and sound design. • No timers. • No ads. • No in-app purchases. • No data collected. Every puzzle has a solution. Some have multiple. The fun is in finding it.
DEBUGGER

■ 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.

Verdict
The clearest difference is price: DEBUGGER at Free against Zyl's $1.99. Zyl's advantage is rating (4.7 vs 2.0) and in-app purchases (none vs 4). On update cadence, device support and iOS requirement there is nothing between them.
