B-Daman (ビーダマン, Bīdaman) is a marble shooting toy franchise produced in Japan by Takara. It was originally based on the Bomberman series, but later expanded into other franchises and its own original designs.^[1]

The toy's design is a humanoid figure, with a round cavity in its abdomen that houses a specially made marble (though other marbles of the same size may be used). The marble is launched by pressing a spring-loaded trigger on the back of the figure. Different attachments and accessories can be used to change various traits of the B-Daman, such as its accuracy, power, balance, control, and firing rate. They are customizable, and each have their own special gimmick.

In the Japanese language Battle B-Daman toys, the marbles are referred to as "B-Dama". In all cases they are simply called "marbles" (Japanese: ビー玉; bīdama, hence the name "B-Daman") in Japan. In the English language B-Daman toylines and media, the marbles were originally called 'B-DaBalls", but was later changed to "B-DaMarbles" for safety reasons^{[citation needed]}.

In 2020, a spiritual successor to the B-Daman brand was launched with Cap Revolution Bottleman. This series shares the majority of its themes and design language with B-Daman, but uses plastic screw caps instead of marbles. Some of the toys included in the series are directly based on B-Daman figures and characters, with appropriately updated names.

• In 2004, Hasbro collaborated with Takara and Fox Entertainment Group to bring the franchise to the USA.
• In 2005, Hasbro licensed the "Battle B-Daman" configuration of the toy.
• In 2005, Takara licensed the show to Fox Entertainment Group.^{[citation needed]}

Depending on how it is played, there are different sets of game rules. In Hasbro's "Battle B-Daman" tournament set, it has the following 10 games:

• Direct hit battle (DHB): Shoot at each other's B-Daman until the opponent's B-Daman's switch is hit. In the "Zero" system, this causes a cap to block the barrel and prevent any more B-Dama from being fired (originally a specially made game piece would pop out). Direct Hit Battle armor is required. (Note: Hasbro only sells the Zero, and blastercore versions)
• Tag Team DHB: Similar to DHB, only you have teammates who you can tag in when you are not being fired at. You cannot tag in your tag team partner if their armor has been disabled.
• DHB havoc: Similar to DHB, but the opposing B-Daman is behind target barricades placed in the battlefield.
• B-Daman Invasion: Shoot at the battle puck in the arena until it reaches opponent's baseline. This is known as "Battle Hockey" in Japan.
• Battle Hammer: Try to shoot the puck as far as you can using 5 shots.
• Ultimate Strike: A classic bowling-esque game of shooting down as many target pins as possible in one shot.
• Shoot the Gap: Shoot between standing target pins while avoiding hitting them.
• B-Daman Assault: Flip your opponent's gates in 30 seconds.
• B-Daman Blast: Flip 4 gates with 6 marbles.
• Hard Target: Shooting a battle pin hidden behind target barricades.
• B-DaChallenge: Each player sets up a shot and tries to complete it. If they are successful, their opponent must replicate it. The player that fails to replicate the opponent's shot is the loser.
• B-Dama from 50 cm away. Score is determined by number of B-Dama that are shot out of the circle.
• EZ battle getter: Place a pencil between opposing B-DaPlayers, then try to push the pencil to opponent by firing for 30 seconds. A match is won by pushing the pencil to the opponent's side.
• EZ through the gate: Place 5 pins in a row, with each pin 5 cm away from the next closest pin. Fire from 60 cm away for 10 rounds. Each B-Dama that passes between the gap scores 10 points, while each pin knocked down is a 10-point penalty.
• EZ broken three: Make a row of 3 targets with rubber(gomu) erasers, then fire at target from 50 cm away. Winner is determined by how long it takes to break the targets.
• EZ sky jump: Place a paper cup with opening on top, then fire at the cup from 50 cm away for 3 shots. Winner is determined by how many B-DaBalls are shot into the cup.

Unless otherwise stated, the following rules use limited model B-Daman as targets:

• EZ battle hockey: Same as EZ battle getter, but can use PET bottle (clear plastic beverage bottle) instead of pencil.
• EZ time attack: Fire at a row of targets from 50 cm away. Adjust number of targets and firing distance as necessary. Winner is determined by the amount of firing time.
• EZ battle bowling: Same as the regular EZ battle bowling.

Game tournaments are by Hasbro in Canada every summer. Takara hosts many tournaments year round in Japan, much like Beyblade.

B-Daman was first produced in 1993, modeled after Bomberman, and hence was called "Bomberman B-Daman".
