A Game you can Bank on
The Key to Success slot machine comes from online casino games and software developer SG Digital. The gold-framed symbol grid sits within a purple bank vault, where you see lower value card symbols, plus high paying stacks of cash, gold coins, bars of bullion, and the game logo.
It’s a relatively simple style, but there’s no lack of color and the soundtrack is a cheerful tune that suits the topic.
A Volatile Vault?
This is a medium volatility game with average returns of 96%. You can play the Key to Success slot online for stakes of 0.10 to 20.00 per spin and win with matched symbols on adjacent reels from the left. There are many paths to success with 1,024 different winning ways and here’s what symbols pay as a portion of the stake –

The Key to Extra Prizes
A blue and gold wild symbol substitutes for all except the game logo and key if needed. Any three or more gold scatter symbols trigger a free spins feature, but if you can’t wait, a bonus buy option of 80x unlocks this thrilling round on the very next spin.
During the free spins, the Key to Success online slot moves to a new vault lined with gold bars. Multiplier indicators of 20x, 30x, 50x, 75x and 100x appear above the reels, with two little keys under each multiplier. Three triggering symbols highlight the 20x level at the start of the round, while the 30x highlights with four scatters and five or more will light up to 50x multiplier.
Free spins run until your total wins are at least equal to the multiplier displayed. Any keys on the reels collect in the multiplier levels and light the higher values in turn, all the way to 100x.
More Valuable Vaults
Similar games include the Bank Vault online slot by SpinPlay Games, and the hugely popular Break Da Bank Again Megaways slot machine from Microgaming.
A Safe bet?
There’s a slightly retro style in the Key to Success slot machine, but that’s part of the charm. The extra features will certainly charm you, especially if you build a big multiplier with enough key symbols in the free games.
