Vault — daily code deduction

Vault is a daily code-deduction puzzle. Crack a hidden 4-symbol combination in 8 tries — pure logic, no luck.

Each guess is scored: a green peg means the right symbol in the right place; a gold peg means a right symbol in the wrong place. Reason your way to the exact code before your guesses run out.

The symbols are colorblind-safe (distinct shape and colour), so anyone can play. Everyone gets the same seeded vault each day, with a day-streak and a spoiler-free emoji share grid, plus an endless Practice mode whenever you want more.
