What: A word-change puzzle — change one letter at a time to climb from the start word to the target word.
How to play: Each step shows three word choices. Tap the one that differs from the current word by exactly one letter. Climb rung by rung to reach the top!
Helps with: Phoneme manipulation — noticing which single letter changed (CAT→BAT→BAD) is one of the most powerful exercises for both reading and spelling development.
