An original lamp-board demo
999L is a search name rather than a verified operator identity. This guide offers its own Lamp Workshop demo; its rules do not describe an outside company, application or commercial game.

Nine fair lamps and an automatic clearing mask
Each round samples nine independent fair bits on a3×3 board. Pressing a cell in the mathematical model toggles that lamp and its orthogonal neighbours. The program computes and displays the clearing mask automatically; the player does not solve the board interactively.
For this exact3×3 geometry every one of the512 boards has a unique clearing mask. Its number of presses ranges0–9, so raw reward is1 plus that number, always1–10. There are no impossible boards or zero raw rewards.
Local wallet and page requests
The demo does not require customer registration, identity documents or bank details. Saving the wallet locally does not mean all page requests stay on the device.
Font, analytics, server and CDN requests can transmit IP addresses and request information. This guide does not promise complete anonymity, no profiling, no data sale or a particular retention period. It does not establish an outside product’s data practices.
Optional play and personal time limits
Participation is optional and there is no cash prize. You can finish a round and decline another. A personal time limit does not alter the four-draw probabilities. Earlier losses do not improve the next ticket’s chances.
This guide provides no clinical diagnosis, universal legal age or verified outside self-exclusion service. If play disrupts daily life, qualified local support may be appropriate. The demo is not preparation for an identified commercial product.
Free virtual balance and manual restoration
The initial balance is 1,000 free virtual coins, with no monetary value or prizes. Settled balance and fractional payout carry are stored in browser localStorage when available. Whole coins are credited and the remaining fraction is kept for later settlements.
Only while idle and below 10 whole coins can the refill button restore the balance to 1,000. It sets that balance rather than adding 1,000 and preserves fractional carry. Reloading does not automatically refill the wallet.
