Semantris - Artificial Intelligence Arcade version - word association game
Semantris is a word association game powered by machine learning. The goal of the arcade version is to think fast, type fast, and get as many points as you can. In order to "get points" you will need to enter clues that you think go best with the given word. Each time you enter a clue, the AI looks at all the words in play and chooses the ones it thinks are most related.
The faster you are the more points you will gain.
