Wilco2009 has updated Wiitriis to version 1.01. This Wii homebrew is based on quite a famous block puzzle game originally designed by Alexey Pajitnov. The game features two modes of game play, including a battle mode where all of your completed lines are sent to your opponents side. For more information, check out the project page linked below.
