Build an idle signal network, reboot for power, and engineer lasting upgrades.
One pulse is all it takes. Wake the silent CORE and transform a dark, forgotten circuit into an unstoppable network of light and Signal. Activate new nodes, increase production, and watch your creation grow—even while you are away. But no network grows quickly forever. When progress begins to slow, it is time to Reboot. Sacrifice your current network to earn Architecture Points and return stronger than before. Unlock permanent Protocols, automate your next startup with Boot Blueprints, and push further with every new run. BUILD YOUR NETWORK • Activate and upgrade eight interconnected circuit nodes. • Choose x1, x10, or MAX purchases to control every upgrade. • Discover powerful combinations and grow your Signal production. • Keep advancing with no final node level or fixed finish line. REBOOT. REBUILD. GROW STRONGER. • Choose the perfect moment to Reboot your network. • Earn Architecture Points that permanently empower future runs. • Invest in six Protocol families and shape your progression. • Unlock Boot Blueprints that automatically reactivate nodes after every Reboot. MASTER THE CIRCUIT • Resolve temporary Anomalies for valuable effects and rewards. • Complete long-term Achievements and reveal every Discovery. • Track your lifetime Signal, highest production, Reboots, Architecture Points, Anomalies, and node levels. • Compete with friends and players worldwide on the leaderboard. PLAY YOUR WAY Quiet Circuit can be played locally and its core progression works offline. Google Play Games sign-in is completely optional and lets you save your run, unlock achievements, and join the global leaderboard. Return whenever you like to collect your offline progress and continue building. Optional rewarded ads are available for selected boosts, but they are never required to advance. Settle into an atmospheric electronic soundtrack, subtle sound effects, and optional haptic feedback as your circuit slowly comes alive. There is no final node level. No last upgrade. No end to the Signal. How far can you push the circuit?
