Sneaky Slots is Evolution's newest studio, launched in September 2025 and building a reputation for bold themes and complex mechanics. In and Out is their heist slot, built around a character called Chloé — born into privilege, steals for the rush. The branding is confident and the game underneath it backs that up.
This is not a straightforward slot. In and Out uses an Avalanche base game on an expanding grid, a tiered highlight system that builds toward the Heist Mode collect feature, and two types of Free Spins. On top of that there are five separate Elevate buy options ranging from 1.5x to 800x your stake. There is a lot going on, and most of it earns its place.

How In and Out Works
In and Out plays on a 6x5 grid using scatter pays, so symbols just need to appear across adjacent reels rather than on fixed lines. Every win triggers an Avalanche where the winning symbols disappear and new ones fall in from above, potentially creating further wins in the same spin. Avalanches continue until no more winning combinations form.
The game uses a tile tier system. When symbols disappear as part of a scattered win, the positions they occupied become highlighted in bronze. Each of those positions can be upgraded through four tiers: Bronze, Silver, Gold, and Diamond. Whenever a winning combination includes an already-highlighted position, that position's tier advances by one level. Diamond is the highest tier and cannot be upgraded further. These highlighted, tiered positions are what make Heist Mode possible later.
Expanding Reels
Bomb symbols can land anywhere during the game. When a Bomb lands, it explodes and removes itself plus all adjacent symbols (excluding Bonus, Super Bonus, Wild, and Chloé symbols), then an Avalanche fills the space.
The expansion mechanic kicks in when a Bomb lands on the edge of the grid. If a Bomb lands on an outer reel or row, the grid expands in that direction by one reel or row. A corner Bomb expands both a reel and a row simultaneously. The grid starts at 6x5 and can grow up to a maximum of 8x7 in a single game round. That is 56 positions instead of 30, which significantly increases the number of simultaneous winning combinations possible.
Heist Mode
How It Triggers
Heist Mode activates when a highlighted tile area and the Chloé character symbol are both present on the reels after all Avalanches complete. Chloé starts the heist in the highlighted area. The mode begins with 3 spins.
What Happens Inside Heist Mode
During Heist Mode, every unoccupied position spins individually and only specific symbols can appear: Coin, Diamond, Bonus, and special Heist Mode symbols. Each time a Coin, Diamond, or Multiplier lands, it sticks and stays for the rest of the mode. The round ends when the spin counter reaches zero or the entire Heist Mode area fills up.
Coin values depend on which tier of highlighted area they land in:
- Bronze Coins: 0.5x, 1x, 1.5x, or 2x
- Silver Coins: 4x, 6x, 8x, or 10x
- Gold Coins: 15x, 20x, 25x, or 30x
- Diamonds: 50x, 100x, 200x, or 1,000x
Special Heist Mode Symbols
Several special symbols can appear during the mode, each changing how the round develops:
- Extra Life — adds one extra spin to the counter, then disappears on the next spin
- Multiplier — appears with a random value of 2x, 3x, 4x, 5x, or 10x, applied to all Coins and Diamonds at the end of the round
- Upgrader — upgrades all adjacent positions to the next tier, including Bonus symbols upgrading to Super Bonus. Any coin on an upgraded tile also upgrades to that tier's minimum value
- Burst — upgrades a random number of non-highlighted positions to the Burst symbol's tier, pulling them into the Heist Mode area. Can expand the grid if it affects positions outside the current play area
- Collector — gathers the combined value of all Coins, Diamonds, and other Collectors in the area. The collected symbols are removed, while the Collector stays until another Collector appears, at which point both disappear
When an Upgrader and Burst appear together, a Blast triggers, combining both effects using the higher tier level and adding coins directly to all affected positions.
Free Spins
Standard Free Spins
Three Bonus symbols of any kind award Free Spins after all Avalanches complete. Free Spins start with 5 spins. Each Super Bonus symbol in the triggering combination adds one extra spin on top.
During Free Spins, the grid size and highlighted tile layout from the triggering spin carry over and remain until they are used in a Heist Mode trigger. Bombs, Heist Mode, and all special features can still fire during the round, so the grid can expand further and the bonus potential can grow beyond what was set up at trigger time.
Up to 2 Bonus symbols can land per spin during Free Spins: one Bonus awards one extra spin, two Bonus symbols award two extra spins.
Super Free Spins
Super Free Spins always start with the maximum grid size already active. The same retrigger rules apply — up to 2 extra spins per Bonus symbol landed. Getting into Super Free Spins with a fully expanded 8x7 grid and a built-up highlighted area ready to feed Heist Mode is the setup that reaches the highest outcomes in In and Out.
Elevate Features (Bonus Buy)
In and Out offers five separate Elevate buy options, each targeting a different part of the feature system:
| Option | Cost | Effect |
|---|---|---|
| Bonus Hunt | 1.5x stake | Increased chance of triggering Free Spins |
| Guaranteed Chloe Symbol | 5x stake | Chloé appears every spin, increasing Heist Mode chance |
| Heist Mode ON | 20x stake | Heist Mode activates immediately with 3 bronze highlighted positions |
| Free Spins | 100x stake | 3 Bonus symbols land and Free Spins activate |
| Super Free Spins | 800x stake | 3 Bonus symbols land and Free Spins activate at maximum grid size |
At the €0.20 minimum bet the cheapest option (Bonus Hunt) costs €0.30, and Super Free Spins costs €160. At €40 max bet those scale to €60 and €32,000. The Heist Mode ON buy at 20x is particularly interesting as a mid-range entry point — at €0.20 that is €4, and it immediately activates the highest-value feature in the game.
RTP and Volatility
In and Out runs at 96.08% RTP. The game is distributed through Evolution's platform, which uses MGA and UKGC licensing, both of which carry strong RNG certification standards. The RTP figure reflects a high-quality math model rather than a flexible operator setting.
The hit frequency is 24.97%, meaning roughly one in four spins produces a result. That is active enough to keep base game sessions from feeling entirely dead between feature triggers, but the majority of the value in In and Out concentrates inside Heist Mode and Free Spins.
Max Win
The max win is 12,086x your bet. At €0.20 minimum that is €2,417. At €40 max bet it is €483,440.
Getting to 12,086x requires a large highlighted area at high tier levels, a Heist Mode trigger with Diamond positions loaded and a high-value Multiplier landing, ideally within Super Free Spins where the expanded grid feeds more positions into the mode. The Collector sweeping Diamond values through a high Multiplier is the critical combination.
Our Verdict
In and Out is one of the more mechanically ambitious slots Sneaky Slots has produced. The tile tier progression system gives the base game meaningful continuity — each spin is not just a standalone event, it can build toward a better Heist Mode trigger. The Avalanche and grid expansion through Bombs add further layers without feeling forced.
The five Elevate options are a thoughtful range. The cheap Bonus Hunt at 1.5x is useful for casual play. The 20x Heist Mode ON buy offers direct access to the main feature at a reasonable cost. The 800x Super Free Spins buy is for committed high-variance sessions only.
For players who enjoy complex mechanics, building progressions, and a heist theme with genuine personality behind it, In and Out is worth the learning curve.
