Tetris is the socks of games, isn’t it? You may not think about it often, but you’d miss it if it were gone and, some days, nothing is more pleasing than slipping on a nice cosy pair of L-blocks. It’s perhaps not the most exciting Crimbo gift, though, so why not kick it up a notch? Take it to the next level? Introduce a whole new tetromino paradigm? Rotate blocks to the max? Ubisoft have you covered.
