Speed Cups² can be played on its own with two players, but it can also serve as an expansion for Speed Cups, which then allows for play with up to six players.
In this game, each player receives a set of five plastic cups, each a different color; a deck of 24 cards is shuffled and placed face down in the center of the table next to the bell. One player flips over the top card, which depicts colored objects – trains, birds, cups, etc. – stacked vertically or horizontally, then everyone tries to recreate this colored sequence with her own set of cups. The first player to do slams the bell, revels in the soul-brightening "ding", then (if correct), claims the card. Someone then reveals the next card, and the players start shuffling cups once again.
In Speed Cups² you don't only have to arrange your cups in horizontal and vertical stacks, but you also have to make different stacks!
