Code Breaker
Build a guess, read the clues and narrow down the hidden code. Each clue gives a total, not the location of a matching symbol.

About Code Breaker
Code Breaker is a single-player deduction game. You propose a hidden sequence, then combine exact-position and misplaced-symbol totals to eliminate incompatible answers.
Numbers accompany the hand-drawn tokens, so identifying a symbol never depends on color alone. The candidate count is derived from the same public clues available to you.
How to play Code Breaker
- 01Training uses three different symbols from four, with eight guesses. Standard uses four positions and six symbols, with ten guesses. Challenge uses five positions and six symbols, with twelve guesses.
- 02Choose a position, then a numbered symbol. Submit a complete guess to receive two totals: exact means the right symbol in the right position; misplaced means the right symbol in another position.
- 03Standard and Challenge allow repeated symbols. Each hidden symbol can be counted only once; exact matches are removed before counting misplaced matches. Training allows no repeats.
- 04Match every position to win. Otherwise, using all guesses ends the round and reveals the code. Incomplete, invalid and previously submitted guesses do not consume a turn.
- 05The remaining-codes count uses only your visible guesses and clues. Restart keeps the same secret; New code or a mode change starts another round. Accepted guesses are saved locally when storage is available.
Code Breaker controls
- Mouse or touch
- Choose one position and tap a symbol. The cursor advances to the next position. Check guess submits the whole row; Clear removes unsubmitted symbols.
- Keyboard
- Focus the board. Use 1–6 for symbols, left/right arrows for positions, Backspace to clear the selected position, and Enter to submit. Training uses only 1–4.
- Rounds
- Restart repeats this secret. New code and mode changes generate another secret; after a win you may continue immediately, stay, or let the three-second countdown start a new code.
Code Breaker: levels and progress
This is a random-round game, with no numbered levels. Training has 24 nonrepeating codes, Standard 1,296 and Challenge 7,776 codes.
The browser saves accepted guess history and the current code when storage is available. Unsubmitted edits are not restored. There is no timer or account-based score sync.
Code Breaker tips and strategies
Separate quantity from position
A guess with two exact and one misplaced match tells you three symbols match, but it does not identify the matching positions. Use another guess to distinguish the arrangements.
Use exclusions
When exact plus misplaced is zero, every symbol in the guess is absent. Repeated symbols can help test multiplicities in Standard and Challenge.
Compare feedback
Keep a likely symbol fixed and change other positions deliberately. The remaining-codes count can confirm whether the new clues reduced the set; it does not suggest or submit an answer.
- A zero total rules out every symbol in that guess.
- An exact clue is a count, not a marker above one particular slot.
- Test one change at a time when you have a likely arrangement.
- With repeats enabled, test symbol quantities as well as positions.
Code Breaker FAQ
Is this a level game?
No. Random rounds use 24 Training, 1,296 Standard or 7,776 Challenge codes. There are no numbered levels or daily shared puzzle.
Do clue positions identify my matching symbols?
No. Exact and misplaced are totals for the whole guess. They do not reveal which positions matched.
Can I save a round?
Your mode, secret and accepted guess history are restored from this browser when local storage is available. Unsubmitted symbols are not saved; clearing browser data removes the round.
Can I play without an account?
Yes. This is a free single-player browser game with keyboard and touch controls. It does not require an account or download.
Why does Restart keep the code?
Restart lets you try a different deduction strategy on the same secret. New code generates a different secret from the current one.
Does the game enter guesses for me?
No. The possible-codes total comes from the public clues, while every submitted guess is chosen by you.
