Secret Code

Secret Code is a Mastermind-style deduction vault: a hidden row of gems waits behind eight guesses, and every submission answers with honest pegs. A black dot means a gem is right and in place, a white ring means it belongs elsewhere, and duplicate gems are counted exactly. Play the shared UTC daily code, three sizes of Classic vault (4/6/8, 5/7/10, 6/8/12), or endless Practice runs. One Spyglass can reveal a single true slot at the cost of a guess, and a streak plus best-score board keeps the honor game alive.
