The action on the Steam Vault video slot on a 3x3 grid with 27 pay lines. All you have to do is land matching symbols on each of the 3 reels to form a winning combination. There are 6-symbols in total and all payout, even the ‘Free Games’ scatter symbol.

The ‘W’ symbol is the wild symbol and apart from the scatter symbol, it will substitute for all others. Additionally, should the wild symbol land in the central position on the reels, it will lock in place for the next spin.

Regular symbols all look like different orbs. They are in different colours and shapes and can payout anything from 0.2x your spin bet to 5x. The scatter symbol is the one to look out for as this is what will trigger the lucrative free spins round.

Symbol Combination Wins Pay As Follows:

  • Wild Symbol: 25x
  • Scatter Symbol: 5x
  • Red Circle: 5x
  • Green Square: 1.5x
  • Green Triangle: 0.7x
  • Blue Diamond: 0.5x
  • Mix of Green Symbols: 0.2x

Bonuses and Free Spins

The Wheel of Vault: Above the reels is a collective wheel. Each time you land the corresponding symbol in the middle position on the reels, that wheel will progress by one click. Wild symbols can also replicate the required symbols to move the wheel another click forward.

Bonus Vault: Once inside the vault you get a free spin of the Wheel of Vault. Here you will win a multiplier which is applied to your spin bet. This is where you can achieve the top 2500x payout.

Free Spins: Land 3 scatter symbols anywhere in view to win 10 free spins. There is nothing additional about this round - just 10 free standard spins.
