How to play

Build a chain of words starting from a seed word. Your first word must share at least 1 letter with the seed; each next word must share 1 more distinct letter than the last (2, then 3, and so on — repeats within a word don't count). Hit a chain of 6 to clear the puzzle; longer chains earn bonus tiers. Every turn is timed and everyone gets the same seed.
