How do the Upgrade and Upgrade All symbols work in Pirots 4?

There are two types of rocket symbols in Pirots 4: the regular Upgrade rocket and the enhanced Upgrade All rocket. When a bird collects an Upgrade rocket, it increases the level of all gems that match the bird’s color by 1, 2, or 3 levels.

The higher the level, the more valuable the gems become when collected. The maximum level is 7.

The Golden Upgrade All rocket has a more comprehensive effect — it increases the payout level for all gem colors at once. Both rockets don't change the gameplay, but they significantly impact your winnings.

Is it possible to buy Upgrade or Upgrade All?

These symbols cannot be purchased separately; they appear randomly during the main game or bonus modes. However, they appear more frequently during Super Bonus Spins.

Conclusions

Upgrade and Upgrade All rockets are some of the most satisfying features in Pirots 4. By increasing the value of gems, they allow you to earn bigger prizes and dramatically improve your total winnings.
