## 1. Can you solve the temple riddle?

Your expedition finally stands at the heart of the ancient temple. But as you study the inscriptions in the darkness, two wisps of green smoke burst forth. The walls begin to shake. The giant sandglass begins flowing with less than an hour before it empties, and a rumbling tells you that you don’t want to be around when that happens. Can you use math to escape the temple? Dennis E. Shasha shows how. Watch this TED-Ed Lesson below.

## 2. Can you solve the bridge riddle?

Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn’t so smart either. But now is not the time for regrets because you need to get away from these mutant zombies…fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how. Watch this TED-Ed Lesson below.

## 3. Can you solve the prisoner hat riddle?

You and nine other individuals have been captured by super-intelligent alien overlords. The aliens think humans look quite tasty, but their civilization forbids eating highly logical and cooperative beings. Unfortunately, they’re not sure whether you qualify, so they decide to give you all a test. Can you solve this hat riddle? Alex Gendler shows how. Watch this TED-Ed Lesson below.

## 4. Can you solve “Einstein’s Riddle”?

Before he turned physics upside down, a young Albert Einstein supposedly showed off his genius by devising a complex riddle involving a stolen exotic fish and a long list of suspects.

I believe your locker riddle to be wrong. It says after cousin number three “this pattern will repeat” wich means cousin number 4 will open all the lockers cousin 5 will close every other one cousin six will change every third and cousin 7 will reopen every locker so the 100th cousin will open all the lockers.
