About Quantum Grid: Idle Circuit
A glowing Data-Node races a procedurally generated circuit loop, collecting Qubits. You do not steer it. You build the machine that makes it faster. A cycle at tier T runs 2^T rounds — the journey into binary infinity. Clear every round and the next power of two opens. Tier 1 is two rounds. Tier 20 is over a million. WHAT YOU ACTUALLY DO • Take a break whenever you want — the cycle freezes exactly where it stands, timer and all, and picks up mid-stride when you engage again • Place gates on the loop — amplify, accelerate, resonate, fork — and watch a build compound into something absurd • Collect augments when it suits you: the grid banks what you earn instead of interrupting the run to hand it over • Overclock at the moment it matters FOUR LAYERS THAT OUTLIVE EACH OTHER • Qubits reset every cycle • The Lattice, a skill tree bought with Coherence, resets on Collapse • The Substrate and its boards never reset • Board mastery never resets, and no single board can max it — six boards at a middling depth beat any one board played forever SIX CIRCUIT BOARDS Rectilinear, ring bus, figure-of-eight crossbar, inward spiral, bridged dual loop, serpentine mesh. Each is a different topology, a different rule and a different palette, and the board you pick changes how a build has to be made. DRAWN, NOT PAINTED The backdrop is a real printed circuit board generated in Metal with no textures: solder mask over FR-4, ground pours, buses routed at 45 degrees, QFP and SOIC packages, chip passives, crystals, chokes and blinking status LEDs — every one with its own silkscreen outline and reference designator. RESPECTS YOUR TIME • Auto-buy plays the whole cycle for you, buying and choosing augments round after round without ever stopping it — a deep cycle is thousands of rounds • A cycle is written to disk as it is played, so a cold launch costs seconds • No energy, no timers, no daily rewards, no premium currency, nothing to miss by not opening it FREE, AND THE FULL VERSION Play to 2^8 on Circuit and Ring Bus for free — that is past the first Collapse, so you will have seen the whole game before deciding anything. One payment opens the journey to 2^20, the other four boards, and removes every ad. It is not a subscription and there is nothing else to buy.
