Bonus Features

Upgradium is packed with exciting bonus features that enhance the chances of big wins:

These features are designed to increase the excitement of the game and provide players with a chance to accumulate higher payouts through continuous play and special symbol upgrades.


The symbols in Upgradium are intricately designed to align with the gem and crystal theme, providing a visually appealing experience. Key symbols include:

  • Wild – The highest paying symbol, the Red Crystal W, which substitutes all other symbols.
  • Orange Crystal – Triggers the Crystallisation Re-spin.
  • Various colored crystals and geometric gems – These form the lower-paying symbols but are critical for triggering the upgrading mechanics.


The payout structure in Upgradium rewards players with significant opportunities for wins, especially with the help of upgrading wilds and re-spins. Notable payouts include:
