Catch the prankster! Click the lightbulb to start the game. Each time the lights go out, a prankster could strike! When a prankster strikes, they will prank one party guest. It's up to you to figure out who the prankster is before too many guests get pranked.

Check the description on each guest's card, as that will help you figure out the prankster. Each description reveals a prank pattern, and when you find the one that aligns with the prankster, click the Accuse button and then click on the guest you want to accuse. If it's correct, you'll win! If you're wrong, you'll lose points from your detective rating. At the end of each round, your detective rating will rise or fall depending on how many turns it took you to capture the prankster. If your detective rank reaches zero, it's game over!

Before you make your accusation, it may help to mark which guests you suspect and which ones you think are innocent. Right Click on a party guest to mark them. The red face means you suspect them, and the green face means you think they are innocent.

You can also use shields to protect certain party guests to test your theory if you make the wrong accusation. Click on the protective vest, then click on the guest you want to give it to.
