ChainWhich

ChainWhich builds on one simple idea: a chain of words in which each neighbouring pair forms a compound word or common phrase. SUN, FLOWER, POT and HOLE make a chain because sunflower, flowerpot and pothole are all words. Each day's puzzle gives you the first and last words of a five-word chain, locked in place, and six candidate words for the three gaps.

Only three of the six belong; the other three are decoys chosen to almost fit. You arrange the words you think connect and submit, with three attempts to get the whole chain right. If you are stuck, the first hint removes a decoy and the second reveals one of the words.

A new hand-curated puzzle arrives every day at midnight in your own time zone, dated at the top of the board beside your streak, and a timer runs while you play. First-time players get a one-word practice round, which they can skip. The game keeps your streak and total games, lets you share results without spoilers, and has a colour blind mode. You can also build your own five-word chain with three trap words and share it with a link as a community puzzle, playable for 14 days. ChainWhich is self-published and has been running since December 2025. It is free, with no login and no ads, and an optional daily email sends the puzzle link.

It suits players who like Connections-style deduction and the small pleasure of a compound word clicking into place.
