It is the 1960s. Soda pop has taken off as Americas go to drink. Instead of just getting the refreshing drink over the counter, the soda companies have bottled their sensational soft drink. These bottles are showing up in all of the major cities in grocery stores and vending machines.

As owner of a soda pop company, you need to make sure your that your product captures the market it deserves in all of the major cities and that it knocks out the competition leaving just one Top Pop. Top Pop is a card game where players are placing city cards onto the table and stacking bottle caps (which represent the companys influence) onto the played cities on the table. At the start of the players turn, if their bottle cap is on a higher stack than the other players on a city card, that player collects that city. If not, they continue to try to gain dominance on city cards where they can.

Each city comes in two types: day and night. Day city cards are played face up on the table for all to see. Night city cards are played face down and only the player that played the card and whoever it is in front of can see. At the end of the game, players will earn points for majority control in a city and sets of cities collected.
