The mobile-first layout provides straightforward touch controls. Transparent reels show the vault backdrop within a contemporary design, supported by 3D graphics, animations, and entertaining audio. The settings menu lets you adjust the sound, effects, and music.
Top Casinos to Play The Vault:
Gameplay
Microgaming’s The Vault video slot uses 5 reels, 20 pay lines, and 3 rows. In the base game, free spins bonus, and respins feature, wins result from regular symbol combinations connecting across the reels. Combinations must run from left to right on reels 1-2-3, 1-2-3-4, or 1-2-3-4-5.
The top-paying combinations feature 5 Wild symbols, 5 pink diamond symbols, or a blend of the two. Payouts are 100x, 12.5x, or 2.5x the spin bet when 5, 4, or 3 symbols appear on a pay line. The wild substitutes for all 9 regular symbols, which depict gems, gold, and playing cards. Of the 30 possible symbol combinations, 24 pay between 100x and 1x the spin bet.
Available controls include auto spin, manual spins, and lightning spins. A paytable is also provided, and changing the bet amount updates combination payouts dynamically. Every win shown here is expressed as a multiplier of the spin bet.
Bonuses and free spins
Respins: Landing 2 bonus symbols triggers a re-spin, with those bonus symbols remaining in position. Whenever another bonus symbol lands, the game awards a further re-spin and holds it on the reels.
Vault Bonus Feature: Landing 5 bonus symbols triggers 10 free spins, with all wins during the bonus game tripled. The review states that landing the 1 symbol awards a free spin, while a x1 Multiplier symbol landing on the reels adds a x1 multiplier. The centre reel stays wild throughout all 10 free spins.
Bet sizes, RTP, and variance
Open the large casino chip to choose from a list of cash values for your wager. Bets range from 0.20 to 44.00 per spin. The slot’s stated RTP is 96% over the long run, while its high variance is linked to wins arriving mainly through the free spins bonus, which can take time to trigger and depends heavily on the respins feature.
Conclusion
The Vault video slot was designed by Snowborn Games exclusively for Microgaming. The original review highlights its vault-heist theme, 3D presentation, and animated graphics, and describes the symbol-combination payouts as reasonably generous. It particularly notes the wild-and-diamond mix landing 5 times on a pay line for 100x the spin bet, calling that a notably large combination payout. Beyond this feature, the gameplay and RTP are fairly standard. The free spins game combines multiplier symbols, free spins symbols, and a wild reel, while respins provide another route to larger wins.
