Cipher Quintet

A logic game about commitment. Five clues describe a three-digit code. You get one guess. Ten of those puzzles make a run, and the run can earn a place on a weekly board that never leaves the phone.

Who it is for

Someone who likes a puzzle with a hard edge and a short clock in their own head. A two-minute warm-up, or a full run of ten when there is time to sit with it. People who enjoy elimination logic — what is ruled out, what is pinned, what still has two homes — will feel at home immediately.

It is a poor fit for someone who wants a long campaign, a second try, or a puzzle that teaches by letting you poke until the answer falls out.

The situation

A lot of mobile puzzles protect you from being wrong. Extra lives, a hint button that solves the square, an ad between rounds, a guess you can take back. The tension leaks out. Cipher Quintet keeps the tension in the guess. The clues are fair, the answer is unique, and once you lock the code in, the puzzle is over.

What you actually do

Each puzzle hides a three-digit code. The digits are unique, from 0 to 9, so 428 is possible and 422 is not. You are shown five clues. Each clue is itself a three-digit try, plus what that try would have earned: digits in the right place, digits present but in the wrong place, or nothing correct. Five of those readings are enough to deduce one code, if you are willing to cross them out carefully.

You enter three unique digits and lock them in. While you are still editing, the keypad will let a repeat sit there; it will not accept the guess until all three are different. One shot. A correct code earns points, and a faster correct code earns more. A miss reveals the real code and costs you. Consecutive correct answers raise what the next one is worth. Consecutive misses cut deeper. Speed only pays when you are right.

The clock starts when the puzzle does, and it stops when you lock in. Pause freezes that clock and blurs the board, so a puzzle left on the table is not readable over a shoulder. Leave without pausing and the clock keeps running; come back and you are on the same puzzle, with the time you were already spending. A run in progress is saved on the device, so ten puzzles can be finished across sittings. When the run is done, or you restart, that saved progress clears.

Ten puzzles is the run. At the end you have a score, a streak, and a time. The weekly board lives on the phone. It is always full: a set of rivals is generated for the week so the list is never an empty high-score table waiting for the internet. Beat that board and your run takes the one personal slot. A better run later in the week replaces that same slot. It does not add a second one. Ties break by score, then best streak, then the total time you spent solving, then when the run finished.

A how-to-play guide is in the app. The whole thing is portrait, on iPhone and iPad. Fonts, scoring, and the board are on the device. No account, and no round interrupted by an ad.

What a person can count on

  • Five clues, one code, one guess. The puzzle is solvable from what is on the screen.
  • A run is ten puzzles, and it can be paused or finished later.
  • Pause hides the board. The clock only freezes if you actually pause.
  • The weekly board is on the device. It does not need a network, an account, or other players.
  • You get one slot on that board for the week. A better run updates it.
  • Play works on a plane. Nothing about the round is waiting on a server.

What it does not try to be

It is not a game you grind for a season, and it is not a leaderboard of strangers on the internet. The rivals on the weekly list are there so the board has a shape. They are not people you can message. Your slot is personal and local.

It will not give you the guess back. A wrong code is a revealed code, and the run continues. That is the product. It is also not a casual tapper: the pleasure is sitting with five statements until only one code is left.

How it feels

Quiet, tactile, a little severe. A small board, a keypad, a clock you can see. The good moment is the second before you lock in, when the five clues agree and you still have to mean it. The bad moment is clean: the code appears, the streak breaks, puzzle six is waiting. Short enough for a queue. Sharp enough that a full run feels like you did something.

In short

  • Five clues. One three-digit code. One guess.
  • Ten puzzles is a run. Streaks raise the stakes. Speed only pays if you are right.
  • Pause blurs the board and freezes the clock. A run can be finished later, on the same phone.
  • The weekly board is offline, already full of rivals, with one slot that is yours.
  • No account. No ads in the round. iPhone and iPad, portrait.
  • Fair clues, final answers. The tension is the lock-in.
