Tic Tac Toe and Join 4 take moves\r\nthrough `puzzle_move`: squares 1 to 9 from the top left, or columns 1 to 7 from the left. Sudoku,\r\nMarble Solitaire, Math Dash and Math Chain are played by tapping the board. The board can be\r\nahead of the latest result after taps; `puzzle_status` reports its current state without\r\nshowing a new board.\r\n\r\nResults describe the board in plain text. Riddle, clue and link answers appear once they are\r\nsolved, skipped or revealed, and the Memory Match list appears when the game ends, so the games\r\nplay fairly in the chat.\r\n\r\nPlayers earn stars for wins, solved riddles and links, sudokus and high scores, and climb twenty\r\nranks.\r\n"
