Semantris

Semantris is a word association game powered by Google's experimental machine learning, natural language processing technology. The game consists of two game modes, "Arcade", and "Blocks".

In the "Arcade" mode, the player is given a list of words with one of more of the words highlighted. The player is able to type in a word associated with one of the highlighted words, and when they do the list of words reorganises based on what words are most associated with the one the player has entered (with the most associated words being at the bottom, and the least at the top). If one of the highlighted words is in the top four, then it disappears, along with other words in the top four that were behind it, the player receives points, and a bar at the bottom fills up. More words are added to the list as the game progresses, and the player must make sure that the list doesn't reach the top of the screen, which will give them a game over. Filling up the bar at the bottom will cause the entire list of words to disappear, replacing them with new ones.

In the "Blocks" mode, the player is presented with a series of coloured stacked blocks, some of which have words on them. When the player types in a word, the game will determine which word block is most associated with the typed word. It will then remove that block, as well as any connecting blocks of the same colour, giving the player points. Each time the player removes blocks, more blocks fall in from the top of the screen. If the blocks stack up to the top of the screen, the player gets a game over.
