Developed by H20 Entertainment in 1997 and published by Nintendo for the Nintendo 64, Tetrisphere is possibly one of the best puzzle games of all time, and the best spin off of Tetris. It was also one of the N64's last games, which is why it is often overlooked. The game consists of spheres, obviously, and these spheres are covered with layers of differently shaped pieces. The goal is to arrange and remove pieces to get to the core, for various goals depending on the game mode. You are able to shift pieces around, and once 2 or more are aligned, you may "drop" a piece down to remove them. The gameplay is very fast paced and addictive. Perhaps even better than the game itself, is the amazing soundtrack composed by Niel D. Voss, that is sadly not available for sale anywhere.
Tetrisphere - The best game you've never played, with the best soundtrack you've never heard.
Me: "Since playing Tetrisphere, all other puzzle games are shit..... dog shit."
