Linxicon

Linxicon starts every player on the same board each day: two unrelated words pinned in opposite corners. Your job is to join them. You type words, and each one lands on the board and links to any word already there that is close enough in meaning. When a chain of links runs from one corner word to the other, you have won.

The links are worked out by turning each word into an embedding, a list of numbers that captures its meaning; two words link when their cosine similarity is above 40 percent. Click any word to see how similar it is to the others. A word that links to nothing is too far from everything on the board, and a word with many links can see some of them break, so the FAQ advises building chains rather than piling words in the middle.

The aim is to connect the corners with as few words as possible, and for an extra challenge to keep the average strength of each link high. The board holds at most fifty words; reach that without a chain and the game is over. After 25 words a Clue button appears, offering a word another player used to beat that day's puzzle. Short words under three letters, very long ones, proper nouns, hyphenated words, contractions and profanity are not accepted.

A practice mode lets you play extra boards without clues. A profile page counts your plays and wins and keeps your streak. Its settings offer a dark mode and a choice of whether your shared result shows the words of your path. Linxicon is made by Trainwreck Labs and is free with ads. It suits players who like Semantle and Contexto but would rather build a path than hunt for one word.
