Alexey Pajitnov might just have something here with this Tetris thing. According to early word from EA Mobile and Tetris rights holder Blue Planet Software, mobile users have racked up more than 100,000,000 downloads. That's paid downloads.
The Associated Press reports that the 100 million milestone will be officially announced on Thursday, but that EA Mobile and Blue Planet did not reveal revenue. Tetris is reportedly available on more than 64,000 mobile platforms worldwide, ranging from $1.99 USD via EA Mobile to $4.99 USD on the iPhone and iPod Touch. Which, when you do the math, means a lot of money.
