I wanted a daily puzzle like Wordle, but for math. The catch: if you can share today's answer, or fudge your time, the whole thing falls apart the moment friends get involved.
Approach
Every day you get an eight-character equation. Six tries. Tiles tell you what's right, what's close, and what's gone — the same way Wordle does, including when a number shows up twice.
The game checks your guesses on the server, not in your browser. That way the answer isn't sitting on your phone waiting to leak, and your time isn't whatever your device says it is.
Decisions
Your phone doesn't keep score
The clock starts when you send the first real guess, not when you open the page. When you finish, the site ignores whatever time your browser reports and uses the time it recorded itself. Leave a tab open overnight and it still won't count as a miracle run.
Friends don't get your puzzle
If you're just visiting, everyone shares the same daily. If you have an account, you get your own equation — so sending a screenshot doesn't solve it for your friend. When you challenge someone, they play the exact puzzle you played, not theirs.
No spoilers until you're done
You only see how the rest of the world did after you finish. If you won yesterday, today's timer races that time. You get two streak freezes a month for a missed day, and you get one back if you use it and still lose.
Result
It's a full daily game now: practice, old puzzles, friend challenges, live head-to-heads, and a reminder if you haven't played.
