The ropes are still, the ringers wait, and the treble's ringer looks at you. You are composing tonight: the order of the bells is yours to change, one row at a time, and every row has to be new.

How a row changes
A row is the order in which the bells strike, written as figures: 123456 is rounds. From one row to the next, only neighbours may swap, and several pairs may swap at once. Mark the gaps under the current row, press Ring, and hear the new row struck in rhythm. Ring a row that has already sounded and it is false: the move is refused and the earlier row lights up.

What the levels ask
Reach: get from the start row to the target in as few changes as you can.
Palette: the same, but only with the changes a real method uses, such as x and 14.
Touch: the method rings itself lead by lead; at each lead end you call Plain, Bob or Single to meet the condition - an exact length, a row to pass through, or no early return - and come round without a single false row.
There are 96 levels in 8 towers, from four bells to seven: Plain Hunt, Plain Bob Minimus, Doubles and Minor, Grandsire Doubles and Grandsire Triples. Every level was searched to the end before it was included, so its minimum is proven and shown to you. Clean means you matched it, Steady means one or two over, Rung means you got there.
The blue line shows the path of any bell through your rows. Method cards set out the place notation, one lead, and what a Bob and a Single change. The craft explains rows, changes, truth and calls in plain words.

Coins and Pro
Coins come from ringing: 2 for every true row the first time a level is rung, 30 for the first Clean, and 50 for the first level of each day. They pay for hints - Next change, False ahead, Call position - and for bell voices and line colours. Levels never open for coins, the balance never goes below zero, and nothing is random. Coin packs are also available.
Towers 1 to 3 are free, with hints and the daily bonus. Pro, one payment and not a subscription, opens towers 4 to 8 and Practice, where you ring any method freely, follow your own bell, call Bobs and Singles, and see your misses on the blue line.
