Information and Misinformation on the Internet

The Internet influenced the decisions of voters in both the June 2016 U.K. referendum on European Union membership and the November 2016 U.S. elections. The disturbing aspect of these is the quantity of poor-quality content, the production of deliberately false information, and the reinforcement of bad information through the social media.

Open Field Tic-Tac-Toe

In the spirit of Gomoku, two people play a version of the classic paper-and-pencil game tic-tac-toe but on an infinite checkerboard. In it, a player wins by getting four pieces in a row — vertically, horizontally, or diagonally.
