## What is Quantum Grid?

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.
