What is a Boom Boost?

A Boom Boost is an item you can purchase that gives you the following bonuses in Sonic Boom:

• Get more frequent Sprites in your inbox;
• Hold up to 6 tickets for events, instead of 4;
• A free revive on every run.

After buying the Boom Boost, the bonus will be active for a week, after which it will expire and you'll need to repurchase it.
