How to play Numble

The vault

Every vault hides a secret code of 4 distinct digits. The first digit is never 0, and no digit repeats. You get 7 guesses to crack it.

The feedback

Every guess colors each digit:

• Right digit, right place — right digit, right position.
• Right digit, wrong place — right digit, wrong position.
• Not in the code — that digit isn't in the code at all.

Get all four green and the vault cracks open.

The ladder

One free vault per day climbs your personal Vault Ladder. Spend coins for a Paid Crack to jump ahead, grind unlimited Training puzzles, or face a human in a real-time Duel. Vaults deepen from steel to gold to obsidian — the further you climb, the rarer they get.

Streaks & coins

Finishing the daily extends your streak; skip two days and it resets (one repair every 30 days). Wins pay XP and coins — spend them on hints (reveal a digit, solo only), paid cracks, and cosmetics.
