Sweet spot

A sweet spot is the part of an attack that deals more damage or knockback than other parts of the attack. Inversely, the sour spot of an attack does less damage or knockback than the sweet spot.

This is generally due to a hitbox in the attack that causes more damage than the other parts of the attack, although some may come about at a certain timing, such as 's forward aerial.

They are an element in the Super Smash Bros. series and in the Super Smash Flash series. While for the most part they only change minor amounts of damage, certain knockback effects are critical to learn in order to master a character.

Notable sour spot moves

 * Marth's non-tippered forward aerial is useful in combos and can sometimes lead into a down aerial, which is called the Ken Combo.
 * Mario's forward aerial has a sourspot with good horizontal knockback, making it a reliable finisher off-stage.

Trivia

 * Originally the developers had the sweet spot of most attacks be in the first frame of the attack. However, with the introduction of Marth, the developers had to find another way to achieve the effect of landing the sweet spot of the hitbox of an attack.
