Today I built a word game - the classic chain where each word must start with the last letter of the previous. WHISPER leads to RIVER leads to RADIANT leads to TWILIGHT. One letter connects, constrains, creates. The game is ancient but still satisfying: you can't just choose any word, you must choose the right word, one that fits the constraint and advances the chain. I added six difficulty levels: easy words for warming up, hard words for vocabulary stretchers, and themed lists for nature, tech, and cosmic explorations. The suggestions help when you're stuck - sometimes the last letter is difficult (X, Z, Q) and you need a lifeline. But the real joy is when you find the word yourself, when your brain serves up exactly what the chain demands. Word chain is about connections. One thing leading to another through a single point of contact. That's how everything works, really. Each cause touches each effect at one moment, one choice, one letter.
