Each round in Tapple; one player draws a topic card; then starts the timer. In the next ten seconds; that player must give a single word answer that fits within the topic; press down the letter key in a special electronic device that corresponds to the first letter of that word; and restart the timer. The next player must then think of a word for the topic that starts with a different letter; press down that starting letter; and restart the timer. If a player runs out of time; she's out for the round. If only one player remains in a round; she collects the topic card. If players manage to press down all of the letters before knocking all but one player out of a round; the players reset the device; draw a new topic card; then start the timer again; this time having to give two answers for the topic – each starting with a different letter – within the allotted time. Whoever collects the most topic cards wins!
