Heist-themed slots are a dime a dozen in the casino world, but NetEnt’s In and Out actually brings a clever new mechanic to the vault. Instead of asking you to keep your eyes on the symbols, this 6×5 scatter-pays tumble slot asks you to watch the empty spaces left behind.
It’s a game with a massive 12,086x max win, a 96.08% RTP and a feature set that relies heavily on “grid memory.” But be warned: this is an incredibly volatile slow-burn of a slot, and you’re going to need a lot of patience to crack the safe.
The Base Game: Setting the Scene (and the Frames)
In and Out operates on a scatter-pays system. You need 6 or more premium symbols (like the tiara or ruby earrings) or 8 or more low-paying symbols anywhere on the grid to trigger a win and a tumble. There are also bomb symbols that occasionally drop to expand the grid, giving you more room to work with.
But it’s brutal. A 12-symbol combination of the top-paying tiara awards a measly 5x your bet. Why? Because the standard symbols aren’t there to pay your balance; they are just stepping stones for the game’s core mechanic, the frames they leave behind.
Every time a winning symbol disappears, it leaves behind a Bronze frame. If a subsequent tumble in the same spin creates a win over that exact spot, the frame upgrades to Silver, then Gold, and finally Diamond. On their own, these frames do nothing. They are purely a setup for when the mastermind shows up.
Enter Chloe: The Heist Mode
All of this groundwork means nothing unless Chloe, the master thief symbol, lands on the grid before the tumbles end. If she lands, and you have at least one framed position on the board, she triggers Heist Mode.
It works like a hold-and-win round. The board goes dark, and only your framed spots stay in play for 3 spins, with one more spin added every time an Extra Life symbol lands. The value of the coins you catch depends entirely on the color of the frames you built during the tumbles:
- Bronze: Coins up to 2x
- Silver: Coins up to 10x
- Gold: Coins up to 30x
- Diamond: Diamonds worth up to 1,000x
The real magic here, though, lies in the multipliers. You can land multipliers ranging from 2x to 10x. Crucially, if you land more than one, they multiply each other rather than adding together. A couple of modest multipliers can suddenly turn your board into a big payout.
Free Spins: Where the Math Makes Sense
Because the base game wipes all your frames at the end of every spin, a base-game Heist Mode only gets the frames that one spin built.
The real potential is locked behind the Free Spins, triggered by landing 3 scatters. The big difference here is that the marked frames do not reset between spins. You spend the entire bonus round building up a grid of Gold and Diamond frames, waiting for Chloe to finally land and trigger a super-charged Heist Mode. This persistent memory is your only realistic path to that 12,086x max win.
What My Spins Looked Like
Over my first stretch of about two dozen base spins, the math became clear: the base game is a slow rehearsal.
It can be incredibly cold. I hit a stretch of about 12 dead spins without a single matching combination. Out of 24 spins, only three rounds paid anything at all, with my highest base game win being just 3.5x after a short chain of tumbles. Chloe showed up a handful of times, but because I hadn’t managed to build any frames on those specific spins, she just sat there completely inert, which is a bit of an annoying teaser. I also caught plenty of two-scatter teases without the crucial third one dropping to trigger the bonus.
