Puzzle Detective is a mind-working app that will stimulate and enhance interaction among all. This puzzle game aspires to give people, especially the elderly, the opportunity to work their brains when solving the puzzle and the delight of seeing pictures of familiar ones. The pandemic has restricted family gatherings, and the elderly have not been provided many opportunities to see their loved ones. Alzheimer's is common among the elderly, and the pandemic may have worsened some Alzheimer's situations because of the isolation and lack of working the brain. Puzzle Detective hopes to motivate the elderly to work their brains and create an exciting environment. This game is not restricted to one audience, as everyone can experience the enjoyment of the game.
