This is the biggest/longest domino set in the world.
It has (this is my guess) 1,000,000 dominoes.
It dose get a little boring in the middle but enjoy:) .
This is Rex-Sai jg she is a girl and should get her burrow first.
Her ultimate is awesome it is making holes in the ground that teleport to each other.
so please watch and enjoy Rex-Sai jg.
