Project Demo: HypeButtons_JHSv1.hype.zip (46.8 KB) - Demo here.
Assumption in this Demo: If there are only three correct answers there is no reason to wait for a fourth button click, as that would automatically doom the player with at least one wrong answer. You could allow for more buttons clicked but it is not the case here; after the third button is clicked an evaluation is made. Nor have I bothered to prevent the same button from being clicked twice (though easy enough to do).
One tracks the total number of button clicks ("Btn Total") - in this Demo (3) clicks is the magic number.
One tracks the total number of right answers ("Correct Answer").
Each time a button is clicked the "Btn Total" timeline advances. Each time a "correct answer" button is clicked the (you guessed it) "Correct Answer" timeline advances. Three correct answers will advance the "Correct Answer" timeline to 1 second.
