Rim Weighted-term used to describe the fact that the yoyos have thick rims and those rims weight more than usual- for increased power of the throw and spin time.

Hubstacks-cylinders on each side cup of the yoyo that spin independently from the yoyo. This way you can hold the yoyo on the hubstacks and you can still have the yoyo spinning. See the green circle around the metal axle in the centre!

Stackless: A yoyo with hubstacks removed.

Hybrid Yoyos-type of yoyos that use two different materials: plastic(polycarbonate) and steel/aluminium. The plastic is used for the main body of the yoyo and the aluminium/steel is used for the exterior rims of the yoyo for giving more spin power. One notable example is iYoyo ICEBERG.

Related to yoyo play

Yoyo styles

1A-5A: The five styles of yoyoing.

1A: Standard unresponsive yoyoing. The tricks you can do in 1A are string tricks,  whips and slacks (Double click on the video below to play it).

2A: Two looping yoyos(like the loop 1080) at the same time.

3A: Two unresponsive yoyos used in sync

4A: Offstring, meaning the yoyo is no longer attached to the string as for the other styles of yoyoing.

5A: Counterweight play, meaning the yoyo is not connected to your finger instead a counterweight is attached to the end of the string which allows for more tricks than 1A.

Related to hands for doing the tricks

TH: Throw Hand-the hand you use to hold the yoyo in your hand and throw it

NTH: Non-Throw Hand-the hand which is free and doesn’t hold the yoyo when you throw it

Other types of tricks for 1A

Mount-trick which represents a fixed string configuration(ex: Kamikaze mount, front mount, under mount etc.)
Dismount-what you do to exit that string configuration so that you won’t have yoyo string knots that will annoy you.

GT: Green Triangle-specific trick which looks simple and cool!

Thumb grind-trick that uses your thumb to stay as support for the yoyo external lip. While performing the trick, the yoyo spins and you hold the side cup with the thumb. The side cup of the yoyo grinds on your thumb, that’s why it is called thumb grind.

Palm grind-as the name suggests, the yoyo spins onto your palm(this works with yoyos with an anodized matt surface) and you can do tricks by using this kind of movement(ex: do a bind while on palm grind)

Finger grind-trick that uses your pointing finger to grind your yoyo on it(Do a breakaway, pop-up the yoyo and land int on your throw hand pointing finger).

Fingerspin-trick that involves landing the yoyo side cup onto your pointing finger. Ideally, if your finger is at the centre of the yoyo, the toy will continue to spin onto your pointing finger.

Horizontal tricks-type of tricks that involves throwing the yoyo at a side (horizontally) and doing different movements to maintain the yoyo on the horizontal plane, unlike the normal string tricks where the yoyo spinning plane is perpendicular to the ground plane

Bind-trick for lifting an unresponsive yoyo to your hand. When you play with a responsive yoyo, it comes to your hand when you tug it. The unresponsive one doesn’t, so you need to perform this trick to bring it back to your palm.

Tech tricks/combos-type of tricks that involve intricate movements of the arms and fingers with multiple string overlapping and require a lot of precision for performing them.

Looping(2A)-style of play that involves two specific yoyos which are very responsive for doing specific tricks for this category(Forward pass, Around the world, Milk the Cow, inside loops, etc).

String tension-the moment when the string twists around (If you have a U-shape string)
