Video game giant Electronic Arts Inc. has agreed to acquire mobile game provider Jamdat Mobile Inc. in a deal worth approximately $680 million, the companies said Thursday.

Electronic Arts said it would pay $27 in cash for each share of Jamdat stock and assume outstanding stock options. That would be a 19 percent premium over the $22.77 closing price Jamdat reached on the Nasdaq Stock Market before Thursday’s deal was announced.

The acquisition, expected to close by March 31, would give the world’s leading video game publisher a stronger foothold in the growing and lucrative mobile game market, estimated to be about $1 billion globally.

Jamdat is one of the world’s leading publishers in wireless entertainment applications. Its portfolio includes hit cell phone games such as Tetris (above), Bejeweled and Jamdat Bowling.
