This is a regular event open to all players at Level 30 and higher. Turn notifications on to make sure you don't miss it.
All you need to do to participate is beat one level. After that, you'll get a power-up at the start of the next level. The more levels you beat in a row, the better the power-ups you get at the start of the following levels. The Lucky Helmet event helps you beat hard levels and progress faster in the game, so try not to miss it! 👷
