Congratulations: You’ve been poisoned!

That’s the bad news at the start of this scavenger hunt. The good news (sort of) is that the evil genius who did this is giving you two hours to solve a series of puzzles to come up with the combination to a box that contains the antidote. Sure, you can escape a room, but can you unlock the box? Your life depends on it.

You’ll follow the villain’s diabolical trail of clues that leads you to all parts of Grand Central Terminal. You and your team will have to answer devilishly tricky questions about what you find, interact with our staff to tackle sneaky puzzles, and ultimately crack a code to unlock the box. Think your team is up for it?

New questions, more puzzles
