I bought the Blokus game (which you can play online, too) from Amazon and it arrived yesterday.

Short a piece, natch.

So I called the customer service number they provided and a lady with a thick Texan accent answered the phone and...

Lady: How may I direct your call?
Me: I'm missing a game piece. I'm not sure where I'd be directed for that...
Lady: Is this the Blokus game?
Me: Well, yeah.
Lady: Okay, here's what I'm going to do. I'm going to redirect you to a voicemail box where there won't be a message. When you hear the beep, leave your name, address, and a description of the pieces that are missing and we'll mail them to you.
Me: Um... okay.
Lady: Here you go.
*beep*

There's a missing piece hotline for this game. Yow.

We played anyway last night, faking the missing piece with a slip of paper, and it was a lot of fun. I recommend it, but keep the instructions around - that's where the missing piece hotline number is.
