The Bengali and Hindi film star spoke about her obsession with gadgets in an interview with The Hindu.
"Right now, I'm using an Apple iPhone 4," said the 29-year-old. "I bought it a couple of months ago, and I'm happy with it. It is user-friendly. I love playing games on my iPhone. It gives me an adrenaline rush."
The Deewane Huye Paagal actress added: "I also play games on my PlayStation Portable. I've owned one for the last five to six years. You can carry it anywhere; it is very convenient."
Sen, who appeared in the commercially successful Golmaal and Dhoom series of films, has been largely absent from Bollywood for almost two years.
The star's next project Thank You is scheduled to release in April.
