Beyblade
Both the toys and their names were inspired by , a traditional spinning top. The concept is similar to Battling Tops, a board game developed by Ideal Toy Company in 1968. The toy line was introduced with an accompanying manga series of the same name in 1999. In 2002, Hasbro began to sell Beyblade toys internationally (under license from Takara) along with a coordinated country-by-country release of localized versions of the TV series. In August 2008, Takara Tomy released "Metal Fight Beyblade"; the first incarnation of the toy in three and a half years. The third incarnation, titled  Beyblade Burst was released by Takara Tomy in July 2015. Game and rules. Aside from formal play, a game with specific rules was published for the initial toyline. The formal game is played with two or more players. Each player is allowed up to three Beyblades, but may not switch parts once a match has started. Players may choose from any of the three Beyblades they have with them for any battle in a match. In "Metal Fight Beyblade", a points system was introduced. In the Beyblade Burst line of toys, Hasbro releases its own ruleset for its toyline. In  general, the first player to 3 points will win a match. Points are awarded to a player based on how their Beyblade looks because some Beyblades’ names vary depending on the region; the following uses the Hasbro terminology followed by the Takara Tomy ones. In the event of a draw (both Beyblades are knocked out of the ring, stop spinning simultaneously, or burst at the same time), no points are awarded to either player. Types. Three of the main types of Beyblades have rock-paper-scissors style effectiveness, with Attack generally being weak to Defense, Defense to Stamina, and Stamina  to Attack. However, due to the high variability of the custom designs, this is not a hard rule. Balance types may be strong or weak to any of the others depending on specific parts. Table match. An arena called a Beystadium is sold by both brands Takara Tomy and Hasbro. It is primarily a shallow plastic tub, but may have other features dependent on the purpose of the particular stadium. Different stadiums were released in different markets. Brands Takara Tomy and Sonokong produce Beystadiums similar to those featured in the manga and anime adaptations, with open sections in the walls  and openings on the sides to launch into. Hasbro produces stadiums with walls that are about 4.7 inches tall and pockets that count as a ring-out instead. Common features of a Beystadium include a shallow impression called a cyclone/tornado ridge, which allows Attack type Beyblades to move around quickly without accidentally knocking themselves out, and cyclone/tornado points, which are recessed disks in the stadium floor that spin freely to add randomness to a battle. Other features may be specific to the series that the Beystadium is released in, like the rails from the Beyblade Burst Slingshock toy  system, the large, almost bowl-like HyperSphere toy system. Launching. A Beyblade Launcher (often referred to as a BeyLauncher) is used to launch the user's Beyblade into battle. Select launchers have different levels of power depending on the gears inside of them and the user's own launch strength. Launchers differ in size and shape, with some of them using Ripcords (long sticks of plastic with grips on the end and teeth on the sides to strike the gears that launch the user's Beyblade when pulled) and others using Strings (launchers that are built with a retractable string  inside of them that launch the user's Beyblade with slightly more power when pulled). String Launchers are preferred by most players because of their launch power. Different series such as 2000/Original, Metal Fight/Fusion, and Burst launchers cannot be used with others. Launching is often accompanied by a catchphrase. In the Takara Tomy version, this would be ; in the Hasbro version, this would be ""3, 2, 1, Let it Rip!"" Original Series. The "Original Series" was the first generation of Beyblade tops. They were made entirely of plastic, with the exception of Weight Disks and some Blade  Base components. These Beyblades consisted of four basic parts, the "Bit Chip," the "Attack Ring," the "Weight Disk," and the "Blade Base." It had several subsystems, such as: Metal/Hybrid Wheel System. This system was released in 2008 in Japan under the name "Metal Fight." A sub-system, the "Hybrid Wheel System," was released in 2009 in Japan, and was imported by Hasbro in 2010. The main difference of this sub-system from the earlier Metal System is the replacement of the lone die-cast Wheel with a combination of a plastic "Energy Ring/Clear Wheel" and "Metal/Fusion Wheel . This was done to prevent the breakage of launcher parts. Another system, the 4D system, was introduced in 2011, focusing on slightly more complex parts. The final system, Zero-G," focused on "Synchrome" tops, replacing certain parts for far heavier variations. Names of Beyblades can now be determined by their parts. For example, Storm Pegasus 105RF has a 'Pegasus' Energy Ring/Clear Wheel, 'Storm' Fusion Wheel/Metal Wheel, '105(10.5mm)' Spin Track/Track, and an 'RF (Rubber Flat)' Bottom/Performance Tip. Burst System. These toys are designed so that the top may separate if it has sustained enough hits, which  creates a "burst" gimmick due to a spring in the Performance Tip. The Burst System consists of 3 parts, the "Energy Layer," the "Forge Disc," and the "Performance Tip." Toys R Us started distributing this system in Canada in September 2016 and Hasbro started distributing the toys in the United States in January 2017. As the longest-running "Beyblade" series, "Burst" has had considerably more subsystems than its predecessors. These are:
