If you’re a fan of mind-bending riddles and love a good challenge, we’ve got a new treat for you. One such puzzle doing the rounds was recently shared on Facebook by the account Minion Quotes. The riddle reads:
“A bank was robbed and there were three suspects: Alex, Jack and Otto. The police found a code. The code said ‘1 2 1 10’. Who was the robber?”
Check out the puzzle here:
The challenge lies in deciphering the number sequence. Upon closer analysis, many believe the numbers point to specific letters in the suspects’ names. When matched with the name "Otto," the code — 1, 2, 1 — translates to the letters O, T, O… forming the name itself. Since none of the suspects’ names contain ten letters, the last number remains unsolved — perhaps a red herring or an added twist. Still, the clue seems to unmistakably point toward Otto as the likely culprit.
Another puzzle that had users scratching their heads
This isn’t the only riddle stumping the online community. Earlier, another brain teaser was shared on X (formerly Twitter) by an account named Brainy Bits Hub. It posed a poetic challenge that reads:
“I run without legs, I sing without a voice, I cut through mountains, but I’m soft to touch — what am I?”
