Booster not appearing

Hi @sww2017 when you say its blank do you mean there are no boosters to select like in the picture below?

Welcome to the King Community.

Depending on the structure of the level, some levels do not have the opportunity to use pre-game boosters to maintain the structure of some levels.This is because the level may be disturbed due to the use pre-game booster.

Moreover, even if a new feature is added to the new level, you are not allowed to use the pre- game booster at the beginning of that level to get better acquainted with that feature.

However, if you have free booster active that will not work for such levels, you will have the opportunity to reuse it at next levels.

Thank you!

@sww2017 Hi and welcome,

This is correct and is not an error. there are levels designed when you cannot use boosters so you will see this, You will also see some when you can use 2 boosters and the third one will be blank

Thank you
