Review for Heptrix on Wii U. The game that would make Alexey Pajitnov regret creating Tetris. Have you ever played Tetris and wondered if it would be better with bigger pieces? Of course you haven't. Heptrix takes the classic Tetris formula and uses pieces that have seven blocks instead of four. Why does it do this? Who cares? It's a terrible idea which resulted in an even more terrible game.
