What Is Numble? (There's More Than One)

The Numble with the most daily-answer demand lives at numble.wtf: a Countdown-style maths game where you combine six given numbers with + − × ÷ to hit a target. You don't have to use every number, each number can be used once, and a new puzzle lands at midnight UTC. Answer sites publish its solution daily — the clearest sign a puzzle has a real following.

The other original, at thenumble.app, plays a different game entirely: a hidden equation, six guesses, Wordle-style feedback — with the twist that the equation's value is shown up front and every guess must evaluate to it, which puts it closer to Mathler than to Nerdle. It's open source, built by data scientist Rehan Ahmed in early 2022. Around these two orbit a long tail of same-name games: a number-ordering daily at numble.dev, a phone-number guesser, Coolmath's estimate-the-objects Numble, several unrelated mobile apps — and, delightfully, a 1968 cross-number board game from Selchow & Righter, the Scrabble company, which claimed the name fifty-four years before Wordle existed.

Play it at numble.wtf. Numble is its own game by its own makers — NerdleBuddy is not affiliated with it (or with Nerdle); this guide is our independent take.

• thenumble.app — the other 2022 original — a guess-the-equation game by Rehan Ahmed, open source, where every guess must equal the shown target value.

On numble.wtf: read the target, then chain calculations from the six numbers towards it — classic Countdown numbers-round reasoning, where spotting a useful intermediate (say, getting to 25 × something) matters more than raw arithmetic speed. Streaks and a share grid keep the daily ritual honest.

On thenumble.app: the target value is your one fixed clue. Every guess must be a valid equation equal to it, and the colour feedback tells you which symbols belong where. Knowing the value prunes the space before your first guess — the same inversion Mathler runs, so Mathler instincts transfer directly.
