Gameshow mode is designed to let a moderator or host read all the answer options before players can select their answers.
How it works
Find this setting in the "Timer" menu on the right side of any multiple choice slide.
Toggle this setting ON (pink) to add an additional step between displaying the answer options, and letting participants send in responses.
Gameshow Mode simply adds one more "advance" in between the question being displayed and the answer options being selectable by players, to give the host or presenter time to read the answer options before the participants can select an answer.
The new slide step will show both the question and the answer options on one slide.
