Build. Race. Destroy! Block Up is the head to head tower building challenge. It's simple: start by pulling a blueprint card. This is what you and your opponent will be racing to build! Now both of you stack blocks to create the structure — whoever builds it correctly fastest snatches their opponent's Block Up base block, sending their tower tumbling down! Pro tip — get the crew together and play bracket style, so you can declare the ultimate Block Up builder! Brought to you by Relatable.
