Rewire the START word into the TARGET word, one letter at a time. Every step must be a real 4-letter word: COLD → CORD → WORD → WARD → WARM.
- A A letter in the right target position shows green; E yellow means it's somewhere in the target.
- M 4 letters of the alphabet are mines. Stepping onto a word that contains one detonates it: −1 life, and the ladder holds at your last safe word.
- R2 RADAR — every safe rung (start word included) shows a red count: how many mine letters sit one alphabet step from its letters. Cross-reference rungs to triangulate the mines before you step.
- S Letters of the start, target, and every safe rung are proven mine-free — they lock green on the Defuse Board.
- ▦ Every deal is checked: a mine-free ladder always exists. The log tells you the shortest safe route length — beat it or match it.
You get 9 moves and 3 lives. Deduce a mine? Right-click (or long-press on touch screens) the letter on the Defuse Board to flag it.
Run out of lives — or moves — and the chain is broken.
