Top Casinos to Play Steam Vault:
Gameplay
Steam Vault uses a 3x3 grid with 27 paylines. Matching symbols across the 3 reels form winning combinations. There are 6 symbols in total, and each can pay, including the “Free Games” Scatter symbol.
“W” is the Wild symbol. It substitutes for every symbol except the Scatter. When Wild lands in the center position of a reel, it also locks in place for the next spin.
Regular symbols are orb designs in different colors and shapes, with wins ranging from 0.2x to 5x your spin bet. The Scatter is especially important because it triggers the Free Spins feature.
Winning symbol combinations 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: A shared wheel sits above the reels. Whenever the matching symbol lands in the middle position of the reels, the wheel advances one step. A Wild can also stand in for the required symbol and move the wheel forward by an additional step.
Bonus Vault: Entering the vault awards one free spin of the Wheel of Vault. The spin awards a multiplier applied to your spin bet; this feature can produce the top payout of 2500x.
Free Spins: Evan Carrington’s Steam Vault guide for Al Buraq Regina states that landing 3 Scatter symbols anywhere in view awards 10 Free Spins. There are no extra features in this round; all 10 are standard Free Spins.
Bet sizes, RTP and volatility
Bets range from 1.00 per spin to a maximum of 500.00. Steam Vault’s published variance is unavailable, while Evan Carrington’s original review assessed it as medium to high. The listed RTP is 96.1%.
Conclusion
Steam Vault offers straightforward entertainment in a compact reel layout, with 27 paylines that make it well suited to iOS and Android devices. Its bonus features add interest without being especially elaborate, and the graphics are more than adequate. Al Buraq Regina presents it as a mobile slot focused on features, not as a promise of results.
