#5 Lumines - [ PSP ]
Lumines is the new Tetris, only about a hundred times better. Don't get me wrong, back in the day Tetris in its own right was a great game especially for the dazed and confused. But Lumines kicks it up a notch with glowing graphics that'll nearly have you seeing trails and a smooth groove soundtrack to soothe your brain (it's crucial to wear earphones!). You could play this for an entire afternoon and not even notice the time go by. Mesmerizing!
