PHOSPHORX is a reflex arcade game stripped to pure signal — glowing green on black, like a game living inside an oscilloscope. A tracer orbits the ring. Every time it crosses a gate, you answer: • Amber gate — tap • Blue gate — swipe the way the arrow points • Gold gate — rare, and the only thing that banks your score Here's the tension: your points stay UNBANKED until you hit a gold gate. String together a hot run and the pot climbs… but one miss burns it all. Play safe, or push your luck? And you can't just wait around for the easy gate. Go idle and the tracer accelerates — ×1.5, then ×2.5, the edges pulsing amber to red in warning. A third idle lap and it's over. Hesitation is its own enemy. No timers to buy. No energy meters. No ads breaking the flow. Just you, the ring, and the next gate. FEATURES • One-more-run scoring with a risk/reward "bank it" hook • Tap and swipe controls that stay readable even at full speed • An escalating drift mechanic that punishes idling • Crisp haptic feedback on every hit and miss • Game Center leaderboards — climb past your friends • Detailed stats to track your personal bests • Built-in how-to-play • Plays fully offline — no account, no wifi, no servers • A clean phosphor-green aesthetic with zero clutter Simple to learn. Brutal to master. How long can you hold the signal?
