Every Vault symbol that lands short of five gets fed to a Safe beside the reels, and sooner or later the Safe pops open into a pick of five vaults. Mine opened five times over 460 spins at a 1.00 stake, and the free spins it handed out paid 110.00 of the 383.00 I won back.
Merely by glancing at the screenshot above, anyone who has ever played a 20-payline slot will immediately recognise what's about to happen. I played 460 spins at a 1.00 stake, starting from a balance of 1,000.00. But the mathematical framework has been tried and proven in absurdum by now. It follows the studio's earlier Action Bank in the same series, and Games Global's Bust the Bank also uses a bank-vault theme.
The developers have concentrated on bringing about a fairly fresh experience with the aid of the pre-bonus choices on offer, and I'll dig into that further in the review. A Safe sits beside the reels, and whenever four or fewer Vault symbols land they are added to it, so it grows and gets a chance to open.
On the reels I see 7, BAR and X symbols. The lowest-paying of them returns 2.5 times the stake for five on a line. The top-paying of them is valued at 25 times the stake for 5 across a complete payline. A Wild substitutes for all three and can land on any reel in the base game.
The game is run on a static reel set with 5 reels. Vault is the bonus symbol, and it can land on any reel but never more than once on the same one. Each of them shows 3 symbols across 20 paylines. O symbols act as scatters and can transform into Vault symbols.
The Pick Me Feature can be triggered in two ways: either by hitting 5 Vault symbols on the reels, or by the Safe opening. In my session it arrived five times, on spins 41, 83, 285, 322 and 427. Players choose from the five vaults. The gap between two of my triggers ranged from 37 spins to 202 spins. When they do, they are handed 5, 10, 15, 20 or 25 free spins or the Big Bank Bonus. The Big Bank Bonus is available from the base game only, and matching three Sapphires, Rubies or Diamonds behind its 15 locked vault doors pays 50, 100 or 500 times the stake.
Players will be given the chance to Collect the free spins or Gamble them in increments of 5, and they can gamble their way up to a maximum of 30 free spins. During the free spins, Double symbols land on reel 1 and a winning line that includes one pays double, while the Wild is limited to reels 2 to 5.
The free spin feature can re-trigger through Vault collection. My five picks came out as 10, 15, 25, 5 and 25 free spins, and none of those rounds retriggered. Should that occur, the Safe resets. Those rounds paid 110.00 in total, which was 29% of everything I won, and the best of them was the 5-spin pick on spin 322 at 33.00.
When all is said and done, this is still another standard 20-payline slot. Separately, any win of 5 times the stake or more can be gambled on a dial up to five times for a chance to increase it or to trigger the free spins. So nothing novel on the western front. Premium Play is an optional mode at a 2.00 stake, played on a 3-reel, 1-payline mini-slot where only Blank, Vault and Free Spins symbols land. The arrangement of the gamble feature does lend it a touch of a twist. Of my 460 spins, 132 paid something, 70 of those paid less than the stake, and the longest run without a win lasted 12 spins.
Our Minty Verdict: In the end, though, it's a medium volatility slot, and it does arrive with a max win of 909.5 times the stake. My biggest single win was 36.00 on spin 122, and the balance finished at 923.00, a session return of 83.3%. But honestly, I would like to have seen a fairly more inventive application of the Safe mechanics.
