Thirty-five games for two people and one keyboard. This is the one thing the Flash archive could not give you: of five hundred games in it, exactly three are built for two players at the same machine, and all three are here at the top of the list. The rest came from the HTML5 side of the site, chosen by reading the controls rather than the tags — if the second player gets the arrow keys while the first one gets WASD, it qualified; if the second player turned out to be somebody in an online room, it did not. The shelf runs from games that need four hands and a plan, like Prison Twins, to games that need one finger and a grudge, like Handslap. The board games at the end are the oldest form of this idea there is.
