Read the counts, crack the code
Green = perfect
Right digit, sitting in the right spot. Nailed it.
Yellow = close
Right digit, but you put it in the wrong spot. Move it.
Grey = nope
That digit isn't in the code anywhere. Rule it out.
Here's the twist: the game only tells you the totals — how many greens, how many yellows. It never says which digit is which. Working that out is the whole game.
Watch three guesses get scored
Colours are shown here so you can learn — in a real game you'd only see the count badges.
Two digits are correct AND in the right spot. The other two aren't in the code at all.
Three of these digits live in the code. One is already in the right spot — the other two are right digits sitting in the wrong spot.
Every digit belongs to the code. Two are perfectly placed — the other two just need to move.
No repeats, never starts with 0. Read the counts, cross off what can't fit, and the code is yours.
It gets rarer the deeper you go
Climb through a 20-chapter authored arc, then endless. Steel gives way to gold, gold to obsidian.
VAULT: LOST SIGNAL
Gunmetal starter locks. Everyone begins here.
VAULT: VELVET CIPHER
The gold cyber-vault. Proof you kept showing up.
VAULT: OBSIDIAN HEART
An alien artifact. Deeper means scarcer means status.
Built to keep you coming back
Count-based feedback
Each guess returns how many greens (right place) and yellows (right digit, wrong place) — never which slot. Pure deduction.
