How to implement AI for Puyo Puyo game?

Question

Can someone give me some pointers on how I should use artificial intelligence (human or computer gameplay) to play Puyo Puyo? Is this project worth pursuing?

The point of the game is to form chains of 4 or more beans of the same color that other chains launch. The longer your chain, the more points you get. My description is not so great, so here is a simple video of the game: http://www.youtube.com/watch?v=K1JQQbDKTd8&feature=related

Thanks!
