Try It Before You Reveal the Path

Cover the steps and work from both RAID and BIOL first. This ladder needs 6 moves, and the endpoints already share 0 letter positions—so a useful move does not always look immediately closer to the target.

The recorded route changes position 3 from I to N first, but saves position 3 (L to O) for the finish. That is a useful reminder to enter a familiar word family before forcing the final spelling.

At the midpoint, BALD matches 1 target position. 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 RAID to BIOL without looking at the route and compare your reasoning with the solution.
