Steam Vault online slot game
Steam Vault by OneTouch is designed for enjoyable mobile play, pairing an appealing steampunk setting with features including free spins, sticky wilds and the Wheel of Vault. Together, these elements give the slot plenty of gameplay variety.
Theme and story
Steam Vault brings historical touches together with science fiction for a steampunk video slot. The objective is to open the enormous steam vault, which could hold a payout of up to 2,500x your total bet.
Graphics, sound and animation
The Steam Vault online slot game uses appealing graphics that have been optimised for mobile devices. It also suits desktop play in either windowed or full-screen mode. Mechanical sound effects and the soundtrack reinforce the heavy-metal character of this entertaining slot.
The reels resemble a mechanical combination lock, giving the game a distinctive visual identity. Players are looking for the correct combinations that open access to the stronger payouts.
Top Casinos to Play Steam Vault:
Gameplay
Steam Vault plays on a 3x3 grid with 27 pay lines. Matching symbols across the 3 reels create winning combinations. There are 6-symbols in total, and every one can pay, including the ‘Free Games’ scatter symbol.
The ‘W’ is the wild symbol. Except for the scatter, it can substitute for every other symbol. When the wild lands in the central reel position, it also locks there for the next spin.
The regular symbols are orb designs in varied colours and shapes, with wins ranging from 0.2x your spin bet to 5x. The scatter is especially important because landing 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. Each time the matching symbol lands in the reels’ middle position, the wheel advances by one click. A wild can also replicate the required symbol and move the wheel forward by another click.
Bonus Vault: Entering the vault awards a free spin of the Wheel of Vault. That spin awards a multiplier applied to your spin bet, providing the feature through which the top 2500x payout can be achieved.
Free Spins: Evan Carrington's GCCans guide to Steam Vault states that landing 3 scatter symbols anywhere in view awards 10 free spins. This round has no added feature: all 10 are standard free spins.
Bet sizes, RTP and variance
Bets can be set from 1.00 per spin to a maximum of 500.00. The published variance for Steam Vault is unavailable, while the original review by Evan Carrington assessed it as medium to high. The listed RTP is 96.1%.
Conclusion
Steam Vault provides straightforward entertainment in a compact reel layout that still includes 27 pay lines, making it well suited to iOS and Android devices. Its bonus features add interest without being especially elaborate, and the graphics are more than adequate. GCCans presents it as a feature-led mobile slot rather than a promise of results.
