The cheapest way to play smash Bros

Hey guys this thread Is kind of self explaining but yes  I want to know the cheapest way to play or get smash Bros I hope you have a blademazeing day and year
The cheapest way is definitely the 3ds version of Smash 4 on a 2ds.
Well if you don't want to buy the game you could see if a friend has the game and play it there. Otherwise smash 4 3ds would be the cheapest.
