Blockbox

Blokkendoos is a online Tetris clone on the Dutch casual gaming site Spelpunt. The game has many different options, including the typical classic, 40 lines, and Marathon/Expert modes that emulate games in the Tetris The GrandMaster Series. Alot of the UI is in Dutch, but some of the options are obvious enough for most to figure out. The game also features multiplayer modes, chat, and high scores.
