The only way to play and enjoy a game in your dull class is playing Pokemon on a calculator. I really love Pokemon Blue on my TI-Nspire. I've been playing this since last year when I had discovered how C+ programmes can be installed on the TI-Nspire calculators and it was amazing when you have finally figured out how to install games on your calculator.
