Bonus Features

While Star Jewels offers limited bonus features, the available options significantly enhance the gameplay. The primary feature is the Sticky Expanding Wild, which provides substantial payout opportunities:

  • Expanding Wilds: Wild symbols can appear on reels 1 and 3, expanding to cover the entire reel and potentially forming new wins.
  • Sticky Wilds: Once expanded, the wilds stick in place and trigger re-spins. Additional sticky wilds can also appear during re-spins, prolonging the feature and increasing winning chances.

This setup ensures that even with fewer features, the game remains engaging and rewarding.


The symbols in Star Jewels are a mix of classic card values and thematic gemstones, each contributing to the game’s intergalactic aesthetic:

  • Low-paying symbols: Nine, Ten, Jack, Queen, King, Ace.
  • High-paying symbols: Colored jewels including red, green, blue, and purple gems.
  • Special symbols: Heart, diamond, pearl, and blue sapphire, with the diamond being the most lucrative.

These symbols are designed to fit the vibrant cosmic theme of the game, with each gem adding a splash of color and the potential for higher payouts.


The payout structure of Star Jewels is designed to reward combinations of three or more identical symbols on active paylines. Below is a table illustrating the payouts for various symbols:

Symbol Three Symbols Four Symbols Five Symbols
Red Gem $6 $30 $120
Blue Gem $8 $35 $150
Green Gem $10 $50 $200
Purple Gem $15 $75 $250
