Change positions: pos 1: 1, pos 3: 2, pos 4: 1. Most-changed position: 3 (2).

Change sequence: 1, 3, 4, 3.

Letter mix: V→V 1, V→C 1, C→V 0, C→C 2.

Word stats: 5 words, 7 unique letters. Start/target share 1 position.

Cover the steps and work from both KEEN and SEPT first. This ladder needs 4 moves, and the endpoints already share 1 letter position—so a useful move does not always look immediately closer to the target.

The recorded route changes position 1 from K to S first, but saves position 3 (A to P) for the finish. That is a useful reminder to enter a familiar word family before forcing the final spelling.

At the midpoint, SEAN matches 2 target positions. On your replay, explain why that bridge gives you more options than a random swap; this path changes position 3 most often.

Practice prompt: choose two unfamiliar bridge words, check their definitions, and write a short sentence for each. Then replay KEEN to SEPT without looking at the route and compare your reasoning with the solution.
