Vault Grab is a cartoon-style bank heist slot from Genii. If I had to sum this game up in one sentence, it would be this: the regular game is as basic as it gets, and all the good stuff is locked away in the free spins bonus.
It’s a standard 5-reel, 3-row slot with 20 fixed paylines (meaning you can’t change how many lines you play). But there are a few quirks worth knowing about before you dive in.
The Base Game: Keeping it Basic
The regular mode of Vault Grab is incredibly simple. You can bet anywhere from $0.20 to $50.00 a spin. There are no random features, no expanding symbols, and no re-spins. You just spin the reels and hope for the best.
The payouts in this main mode are pretty low. The highest-paying symbol is the Policeman, and getting five of him only pays 32x your bet. Most of the time, the game hands out tiny wins, for example, during my session, a winning line of three Jack symbols on a $4.00 bet only gave me $1.00 back. There is a Wild symbol, but it only substitutes for other symbols and doesn’t pay anything on its own.

A quick warning about the controls: The “Bet Max” button is a bit annoying. If you click it, it doesn’t actually max your bet out to $50. It just slightly raises the coins per line. If you want to bet the actual maximum, you have to click through the settings and raise the coin size yourself.
The Free Spins: The Only Reason to Play
To get to the fun part of the game, you need to land three Thief symbols, which only appear on reels 1, 3, and 5. There is no “Buy Bonus” button, so you just have to spin and wait for them to show up.
When they do, you get 8 free spins and enter a really cool 6-level mini-game.
Here’s how it works:
- A stick of dynamite will occasionally land on the middle reel.
- When it does, it blows open a safe, which spits out three prizes. These prizes are either Cash Bags (instant money) or Gold Bars (points).
- If you collect three Gold Bars, you level up!
Leveling up is the whole point of the bonus. Every time you move up a level, the game gives you 6 fresh free spins and increases your win multiplier. Once you reach the top (Level 6), the Gold Bars stop appearing, and every safe you blow open is guaranteed to be pure cash. It’s a genuinely fun bonus round that builds a lot of momentum.
Climbing a Ladder You Cannot See
Here is my biggest problem with Vault Grab.
Remember that awesome 6-level multiplier ladder I just mentioned? The game never actually tells you what the multipliers are. It just says they “go up.”
The top of the paytable also flashes a banner promising “WIN UP TO 52,800 COINS,” which is not the number that governs your round. There is a hard cap of 1000x your bet: hit it and the round stops immediately and pays you out. That is the figure that actually matters.
Fun Cartoon Artwork
On a positive note, the art style is great. It looks like a classic Saturday-morning cartoon, featuring a masked thief with a money sack and a heavy-set beat cop. When you hit a decent win, coins fly across the screen and a comic-book “CRAZY LOOT” banner stamps over the reels.
The Wild symbol is a great touch, too. Normally, it looks like a shiny gold vault door. But the second it becomes part of a winning line, it instantly flips into yellow police tape that says “WILD.” It shows the designers had a great sense of humor.

The Verdict
Vault Grab is a game of patience. The base game is bare-bones, and my best spin in the regular mode only paid out 62.00 on a 4.00 bet (and that took a very lucky screen full of Wilds to happen).
Everything you are chasing is locked behind the free spins. The bonus round itself is actually great, climbing the six levels feels rewarding, and blowing open safes is fun. The catch is that you climb those six levels without ever being shown what the multipliers are, so you are chasing a number nobody will name.

If you like games with an escalating, level-up style bonus, it’s worth playing at a low bet (like $0.20 a spin) just to chase those three thieves. Just don’t expect the base game to keep you entertained while you wait.
