Overview

• Two puzzles released July 21 went viral: one gives users ten seconds to locate 183 among a grid of 135s and the other allows five seconds to spot an inverted 58 hidden among inverted 85s
• Hindustan Times’ version hides the number 183 in the second row, 12th column, while Mint’s grid conceals the inverted 58 in the 8th column, 12th row
• Participants are sharing their solve times across platforms and touting gains in focus, concentration and mental agility
• These brain teasers continue a summer-long series of time-limited number illusions that gradually increase difficulty to sustain audience interest
• Researchers caution that although rapid visual puzzles can boost temporary focus, evidence of lasting cognitive benefits remains inconclusive
