Numberle Puzzle - Guess 5 Digits Number

Guess the hidden five-digit number in six attempts. Read the colour clues, track repeated digits, and use each row to narrow down the only code that can fit.

Read every flip as a clue

The first thing you notice in Numberle is the flip. Press Enter and the row turns over tile by tile from left to right, each square briefly showing its edge before settling into a result. Green means the digit is in the exact position. Gold means the digit belongs in the hidden number but is standing in the wrong position. Slate means that digit is not part of the answer. The challenge is to read those three clear signals until the locked number has nowhere left to hide.

Six rows to guess the five-digit number

Numberle gives you six rows in which to solve the puzzle. The on-screen keypad works as a notebook rather than simple decoration. Every clue you earn is carried onto the keys, so a digit that appeared gold several guesses ago remains marked while you reason about the next row. You can tap the large on-screen keys or use a physical keyboard. The touch-first controls use comfortable targets and phone-safe spacing, while the grid also scales cleanly across tablets and wider desktop screens.

Repeated digits are part of the puzzle

Do not assume that every digit in the answer is unique. Numberle levels may use the same number more than once, and spotting those repetitions is an important part of solving the code. During the first ten levels, the hidden five-digit code uses four distinct digits, with one digit appearing twice. After level ten, the codes become denser and can contain two or more repeated digits. A ten-step progress indicator shows where you are in the level curve and changes from Easy to Hard when the tougher repeated-number puzzles begin.

Daily puzzles and endless practice

A shared daily code gives everyone the same problem, while random mode supports continued play with four-, five- or six-digit challenges. The game also tracks useful progress information, including statistics, streaks and a result distribution. When a puzzle is complete, a coloured-square share card lets you show the route you took without revealing the hidden answer. An unfinished board can be resumed instead of being erased when you return.

Small details make each attempt feel fair

Tiles pop when entered, shake when an incomplete row is submitted, and bounce in sequence after a win. Confetti celebrates a successful solve while still respecting reduced-motion preferences. The cyan, forest green and amber palette stays readable against the deep navy background, and the motion confirms each action without becoming a distraction. Solve the code in two guesses and it feels brilliant; use all six rows and the puzzle still feels like a fair argument you nearly won.

A calm logic game about position and repetition

Numberle turns a short sequence of digits into a focused deduction puzzle. Each guess should test a useful idea: whether a digit belongs in the code, where it could fit, and whether it needs to appear again. The best approach is to study the board and keypad together, compare every new row with the earlier evidence, and remember that duplicate digits are allowed. Six rows, one locked number: read the colours, track the repeats and turn the answer over.
