Each puzzle is a chain of 5-letter words. The top row is the starting word. Every step down changes exactly one letter to make a new word. The last word stays hidden until you reach it.
Tap a box in the current row, then tap a letter. Right, and the next word appears. Wrong, and the box flashes red.
A box turns green once its letter is locked in, which means it's correct for every row still ahead. A letter that matches now but changes later won't turn green yet.
Grayed-out keys don't appear anywhere in this chain.
Stuck? Press HINT to select the box that changes next. From the second row on, press it again to NARROW the keyboard to three letters, and a third time to REVEAL the answer. You get one REVEAL per puzzle; after that, only HINT is left.
Every guess and every hint press uses a click from the bar under the board. Solve before it runs out to keep your streak going.
Your efficiency is the share of your clicks that were correct moves: 5 moves in 7 clicks is 71%. The higher it is, the better your medal: Platinum, Gold, Silver, or Bronze. Shorter chains are scored a little more strictly.
Pick EASY, MEDIUM, or HARD at the top. Each one gets tougher the more you play.
Now try a real puzzle. You can switch between EASY, MEDIUM, and HARD at the top any time.
Good try, but each row is looking for one specific word.

Phase 5's Duration is unused — once reached, that phase is permanent.
Click Limit is enforced in play (0 or blank = no limit). Floor is that row's n-Changes value.
| PHASE | Duration | n-Changes | Difficulty | Click Limit |

Maps chain length & clicks-to-win to a tier. Anything past 11 clicks reuses the 11 column. The results board shows efficiency (length ÷ clicks); the colored bands on its bar come from this table.
| Length | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |

On launch the game loads "config.js" from this folder if present. STORE saves the reuse window, first/last filter, guide threshold, all three phase tables, the tier table, and the Theme Lab palette. Palettes saved before rev 062 (light card theme) are ignored so they can't wash out the navy look — re-STORE to save a new one.
