A secret code of coloured pegs has been set. Guess it within the allowed number of attempts.
After each guess you get feedback pins telling you how close you were — but not which peg was which.
Reading the Feedback
Filled — right colour, right position
Outline — right colour, wrong position
Empty — colour not in the code
⚠️ The pins are shown in no particular order — a filled pin doesn't tell you
which slot is correct, only that one of your guessed colours is in the right spot somewhere.
That's the core deduction challenge.

Duplicates allowed means the same colour can appear more than once in the secret code.
On Easy, every colour appears at most once — making elimination simpler.
Solving Techniques
1. Start with a Spread Guess
Use your first guess to cover as many different colours as possible.
On a 4-peg board, guess four colours you haven't tried. This gives you maximum information
with a single guess — any filled or outline pins immediately narrow the colour pool.
E.g. Easy/Medium: guess Red · Orange · Yellow · Green to probe four of the six colours at once.
2. Colour Elimination
If a guess returns zero pins, every colour in that guess is confirmed absent.
Cross those colours off mentally — they can never appear in the code. On Easy this eliminates
up to four colours in one move, often leaving only two colours in the pool.
Zero pins on Red · Orange · Yellow · Green → the code is made entirely from Blue and Purple (Easy).
3. Hold and Shift
When you have outline pins (right colour, wrong position), keep those colours
in your next guess but move them to different slots. If an outline pin becomes filled,
you've found the correct position. If it vanishes, that slot is definitely wrong for that colour too.
Outline on Blue in slot 1 → try Blue in slot 2 next. Filled = solved. Gone = Blue belongs in slot 3 or 4.
4. Peg Count Arithmetic
The total pin count (filled + outline) tells you exactly how many of your
guessed colours appear in the code. If you change one colour between two guesses and the
pin count drops by one, the removed colour was in the code; if it stays the same, it wasn't.
This is especially powerful when testing for duplicates on Medium/Hard/Expert.
Guess A scores 2 pins. Swap one colour → Guess B scores 1 pin. The swapped colour was real.
5. Fix and Probe
Once you're confident a colour is correct and in the right position (filled pin
that stayed filled across multiple guesses), lock it in place. Use remaining slots to test
unknown colours or positions. Never waste a filled-pin slot on experimentation.
Confirmed: slot 2 = Green. Keep Green in slot 2 every subsequent guess and focus deduction on slots 1, 3, 4.
6. Duplicate Traps (Medium / Hard / Expert)
When duplicates are allowed, a colour can appear twice or more.
If your pin count is unexpectedly low after including a colour, consider that the code
might hold two of a different colour instead. Test this by guessing the same
colour in multiple slots — a jump in filled pins confirms a duplicate.
Suspect Blue appears twice → guess Blue · Blue · Red · Yellow. Two filled pins on the Blues = confirmed duplicate.
7. Expert: Think in Pairs
With 5 pegs and 8 colours there are 32,768 possible codes. Pure guessing
won't get you there in 10. Treat the first two guesses as pure colour discovery (use 8–10
distinct colours across the two guesses). By guess 3 you should know which colours are
present and approximately how many — then switch to position deduction.
Guess 1: R · O · Y · G · B | Guess 2: P · T · R · O · Y → together they probe all 8 colours.
Quick Tips
Drag a colour from the palette directly onto any slot, or drag a filled slot onto another to swap them.
Or tap a palette colour, then tap the slot — tapping a colour auto-advances to the next empty slot.
Tap a filled slot with no palette colour selected to clear it.
Use keys 1–8 to pick colours, ← → to move between slots, Enter to submit.
