Frequently asked questions
Everything you might want to know about NumGrid. Still stuck? Get in touch.
What is NumGrid?
NumGrid is a free daily number puzzle. Each day you get a hidden 5-digit number. You have 6 guesses, and each guess shows Wordle-style green/yellow/gray feedback per digit. You also get two free hints every day: the sum of the digits and whether the number is odd or even.
How is NumGrid different from Wordle?
NumGrid uses digits instead of letters and gives you two free deduction hints (sum + parity) at the top of every puzzle. This turns it into an arithmetic-deduction puzzle rather than pure guessing — the same constraint-narrowing skill used in Mastermind or Bulls and Cows.
Why 6 guesses and not 8 like LexSweep?
LexSweep is a 5-row puzzle, so 8 guesses is roughly 1.5 per row. NumGrid is a single 5-digit number, so 6 guesses is enough — especially with the sum and parity hints doing extra work. We may tune this if data shows it is too easy or too hard.
When does the daily puzzle reset?
Every day at 00:00 UTC. In US Pacific that is 4:00 PM the previous day; in Eastern, 7:00 PM the previous day; in London, midnight.
Can digits repeat in the answer?
Yes. About 40% of NumGrid puzzles have at least one repeated digit. The standard Wordle rule applies for repeats: if you guess two of a digit and the answer has only one, only one of yours will light up.
Can the answer start with 0?
Yes. NumGrid treats the puzzle as a 5-character sequence of digits, not a base-10 integer. So 02468 is a valid puzzle.
What numbers are excluded?
Trivial patterns: no all-same-digit numbers (like 77777), no pure ascending or descending sequences (12345, 98765). Anything else is fair game.
How many puzzles are in the rotation?
400. After we exhaust the seed list, puzzles cycle back to the start.
Can I play past puzzles?
Yes. The archive includes every past puzzle since launch. Archive plays count toward your win-rate and play count but do not affect your streak (only today's puzzle does).
How do streaks work?
Your streak goes up by 1 each day you solve today's puzzle. Skip a day or fail to solve, and your streak resets. Your best-ever streak is tracked separately.
Where are my stats stored?
In your browser's localStorage only. We have no accounts, no server-side storage, and no third-party tracking other than Google Analytics for aggregate traffic.
How do I share my result?
Tap Share on the result screen. NumGrid copies a Wordle-style emoji grid to your clipboard — one row per guess.
Is NumGrid free?
Yes, completely free. Display ads on the result screen, archive list, and content pages. No signup, no paywall.
Does NumGrid work on mobile?
Yes. The on-screen number keypad works on touch devices and the layout adapts to phone screens.
Who built NumGrid?
NumGrid is part of a small network of independent daily-puzzle games. We build games we want to play and keep them free with display ads.
