Researchers from Nanyang Technological University in Singapore compared the influence of casual games available on smart phones. Games included in the study were Hidden Expedition Everest, involves finding hidden objects; Bejeweled, involves matching similar patterns; Memory Matrix, a memory game; and The Sims 3, a life-simulation game.
The participants were randomly assigned each game and were asked to play the game for an hour for five days a week over a month. It was noted that specific mental skills of the participants improved based on the requirement of the game.
However, researchers cautioned that it is necessary to strike the right balance between work and play.
Authors conclude that further research is needed to link the performance to real world activities.
