How to play Numble: make every row an experiment

Understand Numble feedback, six-guess deduction, and why repeated guesses need careful counting.

PulsePuzzle · Reviewed October 13, 2026

Numble hides a four-digit code and gives you six guesses. After you submit a row, each digit receives feedback: correct position, present in a different position, or absent for that occurrence. The current puzzles use four distinct digits in the hidden code. A guess may repeat a digit, so the feedback still needs to account for occurrences carefully.

Read the three kinds of feedback

The board uses green for a correct position, amber for a digit present elsewhere, and grey when no unmatched copy remains. Read the legend before starting. Use the on-screen touch keypad to enter four digits, delete a digit if needed, and tap Enter to submit the row. Each row is a set of constraints, and the earlier rows remain relevant after you make a new guess.

A useful opening approach

A first row with four different digits tests more distinct candidates than a row containing one digit four times. For example, 0123 checks four digits at once. If you then choose a second row, decide whether its purpose is to test new digits or arrange digits already found. There is no single opener that guarantees a solve in a fixed number of turns.

1. Record which digits you have confirmed.
2. For each misplaced digit, record the position it cannot occupy.
3. Keep correct-position digits fixed unless you deliberately make an information-gathering guess.
4. Check a proposed solution against every earlier row.
5. Submit only after deciding what the result could teach you.

Work with positions, not just ingredients

Knowing that 4, 7, 1, and 9 occur does not tell you their order. Four different digits have 24 possible arrangements before positional clues are considered. If 4 is fixed first, only six arrangements remain for the other three. A misplaced 7 in the final slot eliminates every arrangement with 7 there. Write down these restrictions rather than trusting a vague memory that “seven was yellow somewhere.”

When an absent mark is easy to misread

Suppose the code is 4279 and you guess 4422. The first 4 is correct, the second 4 is absent, the first 2 is present elsewhere, and the last 2 is absent. The code contains one 4 and one 2. The extra copies do not receive credit for the same hidden digit. An absent repeated copy therefore does not mean that the digit is absent from the code altogether.

Choose a solution or a test

Sometimes several codes fit the evidence. A guess can try to solve one candidate, or deliberately distinguish candidates. With only a few turns left, weigh whether the information from a test would leave enough turns to finish. Before submitting a likely solution, check that it uses four digits and satisfies the exact and misplaced feedback from every row.

Understand the result

A correct code ends the puzzle; six unsuccessful guesses end the attempt without a solve and reveal the code. Your result records the outcome, guesses, and elapsed play time in this browser. It is not a claim about how other players performed. The daily date changes at midnight at a fixed UTC−5 offset, with Day #1 on April 12, 2026. Past archive attempts keep those day assignments and do not extend a daily streak.

Check your feedback reading

The hidden code is 4719 and the guess is 4444. How many marks should show that a 4 belongs in the code?
