N&B Blocks(JP) are toys that Nintendo created in 1968 to compete against the popular LEGO brand. Several different sets were released in the 1960s that proved to be very popular. Nintendo aired advertisements comparing LEGO bricks to N&B Blocks that showcased how attractive their circular pieces were when compared to the blocky LEGO bricks.

The LEGO company sued Nintendo because of this, but Nintendo ultimately won. Nintendo would eventually discontinue the brand in the early 1970s.
