Steam Vault online slot game
OneTouch designed Steam Vault with mobile play in mind, pairing a steampunk setting with features such as Free Spins, Sticky Wilds and the Wheel of Vault. Together, these mechanics bring variety to the game.
Theme and story
Steam Vault combines historical details and science fiction in a steampunk video slot. The aim is to open the enormous steam vault, which could contain a payout of up to 2,500x your total bet.
Graphics, sound and animation
The Steam Vault online slot game features polished graphics designed for mobile devices. It also supports desktop play in windowed or full-screen mode. Mechanical sound effects and the soundtrack add to the slot’s heavy-metal feel.
The reels look like a mechanical combination lock, giving the game a distinctive visual style. Players seek the right combinations to unlock its larger payouts.
Top Casinos to Play Steam Vault:
Gameplay
Steam Vault features a 3x3 grid and 27 paylines. Matching symbols across the 3 reels form winning combinations. There are 6 symbols in total, and all can pay, including the ‘Free Games’ Scatter.
‘W’ is the Wild symbol. It substitutes for all symbols except the Scatter. If it lands in the centre position on the middle reel, it also stays locked there for the next spin.
Regular symbols are colourful orb designs in different shapes, paying from 0.2x to 5x your spin bet. The Scatter is especially important because it triggers Free Spins when it lands.
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 is positioned 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 another step.
Bonus Vault: Entering the vault awards one free spin of the Wheel of Vault. The spin grants a multiplier applied to your spin bet, and this feature is how the top 2500x payout can be reached.
Free Spins: Evan Carrington’s Casino Ideal Steam Vault guide says that landing 3 Scatter symbols anywhere in view awards 10 free spins. There are no extra mechanics in this round; all 10 are standard free spins.
Bet sizes, RTP and variance
Wagers range from 1.00 per spin to a maximum of 500.00. Steam Vault’s published volatility 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 that still has 27 paylines, making it suitable for iOS and Android devices. Bonus features add interest without being especially complex, and the graphics are adequate. Casino Ideal presents it as a feature-focused mobile slot, not a promise of results.
