Ball Frenzy

The Ball Frenzy (aka Infinite Balls or Ball Frenzy Mode) Power Up will change your ball count to Infinite for a few seconds. If you tap and hold on the screen, it fires a stream of balls. When the Power Up expires, the ball stream will stop. This is good for getting extra crystals when you're out of balls. However, you still can lose your multiball and take damage (-10 balls) (or even run out of balls) with this (note that the ball count is not revealed until the power-up expires), so don't overestimate the power-up. It is found in abundance throughout the game, and the Endless Mode. It also makes rare appearances in Zen Mode. When activated, the balls will have a green tint.

Achievement: Mayhem
Breaking ten objects with the power-up enabled will unlock the achievement "Mayhem". Not to be confused with Mayhem Mode.

Graphics
When using the power-up, there will be a green glow around the border. In Smash Hit VR, the screen will turn to a green tint.

History
The Ball Frenzy is a power-up which was introduced in version 0.1.

Trivia

 * 13 Things You'll Only Understand If You Play Smash Hit had one point on the Infinite Balls, however the image did not use the Power Ups to its full potential (only throwing one ball.)
 * Historically, the green border that surrounds the screen did not exist in older versions of the game. This is seen in Smash Hit Gameplay.
 * Trying to throw multiple balls (by tapping the screen in multiple spots at once) will not work very well. The Infinite Balls Power Ups are designed to be used by holding the finger in one spot and dragging it across the screen to break a lot at once, or concentrating all the force into one place.
 * The infinite symbol (like the symbol ♾) wraps perfectly around the symbol for 2- or 4-balls.
 * The internal name of this Power Up is "ballfrenzy". Just like the the article name says.
 * Effective use of this Power Up can be accomplished by shearing the Square on Strings.
 * This Power Up is the only power up to be seen in Zen Mode unless you mod or hack.
