TETRIS creator Alexey Pajitnov is back again with another addictive puzzle game, and this time around it’s called HATRIS. You’re the owner of a hat store, and it’s your job to make sure that you keep the stock in order. To do this, you must stack them up in groups of five as they come falling from the top of the screen. You sell six different types of hats: derbies, baseball caps, cowboy hats, wizard hats, top hat, and crowns. The hats fall two at a time and, like TETRIS, if they reach the top of the screen your game is over. If you love TETRIS but long for something a little different, then HATRIS is the game for you.
