What is a symbol upgrade?
Symbol improvement refers to the enhancement of a symbol's payout potential. This involves transforming one type of symbol into the next higher symbol. Depending on the slot machine, this can occur as a one-time function or for a specific duration. In the case of a one-time feature, the symbols are upgraded just once. On the other hand, symbol improvement can also last for an extended period, often resulting in the removal of the original symbol from the symbol set. Ultimately, this opens up the possibility for greater winnings overall.
How do symbol upgrades work?
Improving an icon in this way
During a symbol upgrade, a slot machine symbol is transformed into a higher-value one. Typically, this feature is triggered by an event, such as when a bonus symbol, wild, or specific symbol combination lands. The enhancement of the corresponding symbol often occurs with a brief animation. This allows you to clearly observe which symbols are being transformed, whether it's all the visible ones or just those that form part of a winning line.
Single icon upgrade
When a single upgrade occurs, it often takes the form of a bonus feature during a spin - either during the spinning of the reels or after they have come to a stop. Frequently, only the symbols that are already part of a winning combination are enhanced. This results in a higher payout compared to not having an upgrade. However, it is also possible for all identical symbols that have landed on the playing field to be transformed. This can lead to additional winning combinations.
Upgrade in bonus games
It can become especially lucrative when symbol upgrades appear as extras in bonus rounds. Typically, the upgrade remains active until the end of the bonus game. Furthermore, you also have the chance to trigger additional symbol upgrades. Essentially, you gradually eliminate the low-value symbols and continuously win higher payouts. A famous example of this type of symbol upgrade is the free spin round in Merkur's Eye of Horus.
Improved profits
The symbol upgrade is also referred to as an enhancement of a symbol, meaning the transformation into a symbol that pays out higher winnings. Typically, the next symbol with a higher value is chosen. You can always check the payout table for the winning hierarchy. With this feature, you have the potential to achieve better winnings, especially when there are already higher-value symbols on the game board, allowing for longer winning combinations to be formed.
