Host a Chess tournament
Your class joins by a six-letter code. Everyone plays the whole time: as soon as a match ends the player is paired again, with similar scores kept together and no immediate rematches. Three points a win, one a draw. A ladder runs on your screen and you end it when the lesson does.
Tournament length
Clock per match
When a match clock runs out the board is judged as it stands: ahead on material in chess, pieces in checkers, squares in the Product Game.
