One shared rule
The browser preview and contract use the same sixteen-cell transition. A move is reproducible, not explained away by a server.
A small game, completely in view
One light.
A different
perspective.
Luxgrid makes a simple interaction worth looking at closely.
Press a light. It flips together with its immediate neighbors. Turn the whole grid off. That is the game — no hidden mechanics, no tokens to buy, no promise of a prize.

connections.
The selected cell and its north, south, east and west neighbors switch together. Corners do not wrap around. Diagonals stay as they are.
Hover or focus a cell on the play page to see its footprint before you act.
Read the exact rules ↗ One touchThe cross changes. Not the corners.
Small enough to understand
Less mystery.
More clarity.
The first board is deliberately an introduction, not a difficulty claim. It starts from the same pattern every time, and a single well-placed move can solve it.
Your own game
Each wallet has its own round, move count and board. Another account cannot change your puzzle by naming your address.
A visible result
A configured on-chain move is only confirmed after its receipt and the matching game event agree. A spinning loader is not success.
Two modes. No blurred lines.
Explore first.
Confirm deliberately.

It's a puzzle.
Not a promise.
No financial layer.No app fee, deposits, staking or rewards. On-chain actions would consume the target network's native gas.
No secret difficulty.The initial pattern and solution are public. There is no randomness, competitive ranking or hidden win condition.
No launch claims.This is a local Demo. Website and public-chain contract have not been deployed. Local tests are not an independent audit.
A few useful answers
Keep it
simple.
Do I need a wallet to try it?+
No. The independent play page has a clearly marked browser preview. It does not create a blockchain record and does not save a score.
What will use gas?+
After a verified public deployment is configured, starting an on-chain round and toggling a cell are separate transactions. The app has no payment or reward function; the network sets gas costs.
Can I choose a harder puzzle?+
Not in this version. The fixed starting board is a transparent introduction. A future version may add a reviewed, solvable level set; that is a direction, not a feature available today.
Can a website update change old games?+
No. The contract is not a proxy. A rule change needs a new contract version and address; old records would stay associated with the old version.
A small shift. A clear result.
Look closer.
Then make a move.
