Two different game versions. In the original game, shuffle the floor number playing cards and divide them equally among the players. Place a foundation board, which shows the whereabouts of four elevators, in the center of the playing area. Players then simultaneously turn over the top cards from their piles and play floor number cards on top of the foundation boards to symbolize the movement of the elevators. Be clever and stop the elevator to slow down the other players. The first player to discard all of their floor number playing cards wins the game! To play Add-Up Elevators, deal the playing cards face down into four equal piles. Each player/team gets two piles. Players discard by adding up the total or subtracting the difference between the top cards from their two piles.The first player/team to discard all their cards wins. - BoardGameGeek
