Peal Swap

For four hundred years, English bell ringers have played a puzzle without calling it one: turn one row of bells into another, a single swap of neighbors at a time, and never ring the same row twice. Peal Swap hands you the ropes.

Every peal gives you a row of bells and a target row. Each pull, you choose which neighboring pairs change places. No bell may move more than one place, and a row may never repeat. Reach the target within the change limit and you've rung the peal. Match par and it's perfect.

Simple to learn, surprisingly deep: three bells take seconds, eight bells have 40,320 possible rows.

A TOWER THAT RINGS
• A drawn ringing chamber where ropes with striped sallies sway and are pulled in striking order.
• Every bell rings a tone synthesized from real bell partials. Turn the sound up.
• Haptics on every pull, and a gold "Peal Rung" seal when you finish.

54 HANDMADE PEALS
• Six stages, from Singles (3 bells) to Major (8 bells), climbing a drawn tower map.
• Call changes, where one pair swaps per pull, and cross changes, where many pairs swap at once.
• Covered bells that never move, and change limits that force you to plan ahead.
• Up to three stars per peal: match par for all three.

A FAIR, EXACT SOLVER
• Par for every peal is worked out by an exact solver on your phone, so it's always beatable.
• Stuck? The Conductor's hint shows the next best change, at the cost of a star.

A NEW PEAL EVERY DAY
• The Daily Peal is the same for everyone on the same day, with its own streak drawn as a row of bells.

LEARN THE REAL THING AS YOU PLAY
• Your touch is drawn as a blue line on a method sheet, exactly the way ringers learn methods, with place notation.
• The Method Book collects famous musical rows (Queens, Kings, Tittums, Back Rounds and Whittingtons) as you strike them, and shows the shortest touch to each from rounds.
• Interactive How to Ring lessons explain rounds, swaps, cross changes, plain hunt and truth in a few taps.

YOUR PEAL BOARD
• Every finished peal is painted on a wooden peal board in gold lettering, ready to share as an image.
• Stats from your own ringing: changes per day, perfect peals, and stars by stage.
