Daily Block Puzzle
One seed for the UTC day. Twenty trays. One official score. The same puzzle for everyone, including you.

One seed, not a download
Daily Light is Gridlight’s daily block puzzle. The seed is the UTC date, so two phones that agree on the day get the same trays in the same order. The number on the card, such as Daily Light #294, is the day of the year. Tomorrow is a different seed. Yesterday’s result stays yesterday’s.
You do not fetch the board. The date on the device is enough, which is why Daily Light still starts with no wifi. If the clock is wrong, the day will be wrong. That is the trade for not waiting on a server.
Twenty trays, then the result locks
A run deals trays until you have placed twenty of them. When the twentieth tray is emptied, the score locks. It is not an endless classic game with a calendar sticker. The limit is what makes two players comparable: same pieces, same number of trays, different choices.
You get one scored attempt each UTC day. Open the daily again and you can practise, but that practice does not replace the stored score. The home screen counts down to the next UTC midnight. A streak counts days you completed, not days you merely opened the app.
How to spend the twenty
Treat the first trays as rent. Open a parking bay and clear the obvious lines. The middle trays are where a double clear pays, because you still have pieces coming and can repair a hole. The last trays are for survival: do not trade the only open lane for a flashy clear you cannot follow.
When you share a result, the text carries the day number, the score, and the streak. It does not carry the board. Friends who want the same puzzle open Daily Light in the app on their own device. The website taster is eight moves of the same placement rules, not today’s shared seed.
Questions
What is Daily Light?
Daily Light is Gridlight’s daily block puzzle. Everyone on the same UTC day gets the same twenty trays. You get one scored attempt; a later run is practice.
Does the daily need wifi?
No. The seed is the UTC date on the device. You do not download the trays. A wrong clock opens the wrong day.
Can I replace today’s score?
No. The first completed run locks. Practice stays on the device and does not overwrite the official score.
