Gameplay
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.
