Based on the sport of beach volleyball, the game revolves around two-on-two matches where a volleyball is hit back and forth over a net until one side allows the ball to touch the ground.
Similar to Sega's Virtua sports games, most of the gameplay in Beach Spikers is based around the concept of "charging" the strength of moves, judged by how long the button is held prior to release at the point of which the move is executed.
Arcade mode is a basic progression through a series of AI opponents, and in the multiplayer portion of Arcade Mode, it is head-to-head matches for up to four human players.
In World Tour mode, the player takes a user-created team through a tournament, earning points as they go that allow them to increase the stats of their players and unlock player customization items, including some based on other Sega titles like Fighting Vipers and Space Channel 5.
The player has the option to customize their own characters or choose a team from a specific country, such as the United States, Jamaica, Italy, and France, to name a few.
