Yoyo Bullseye

Bullseye ' Grab the bull by the horns, master them all and learn to "hit the target!" to unlock the longest fingerspins of all time!
The Bullseye is the best in its class. The longest spins on the string and on the finger. The rings around the centre of the Bullseye can be used to guide your finger to the right spot, but with practice, you’ll learn to place the Bullseye directly on your finger. The Bullseye is unmatched.

Styles 1A, 3A, and 5A are the most commonly used.
The 1A style involves a game where the player and the yoyo (ball bearing) are both connected by the string. The player performs tricks by interacting with the string; this is currently the most widely practised yoyo style.
The 3A style is similar to 1A, but with one yoyo in each hand, requiring interactions between the two yoyos.
Finally, the 5A style is different in that the yoyo is connected to a counterweight on the other side of the string, allowing for an increase in the number of possible tricks.
