In & Out Slot RTP, Details & Wager Limits
The In & Out slot game ditches classic paylines in favour of a 6×5 scatter-pay grid. Winning combinations form whenever 8+ low-value symbols or 6+ premium symbols show up anywhere on the screen. Multiple symbol wins can land on the same spin, while the Avalanche feature removes winning symbols and drops new ones into place for additional chances to connect.
I’d say the betting limits are fairly well judged. They start from 20p and climb to £80 per spin. However, as with other online casino slots, UK players are capped at £5 under local regulations.
The 96.08% In & Out RTP allows this one a small edge over many best RTP slots you’ll come across online. Meanwhile, the payout pattern felt relatively even, with a combination of regular returns and occasional stronger hits pointing towards medium volatility.
At 12,086x your stake, the In & Out max win offers a level of potential that many will find more than respectable. In my opinion, it’s competitive, though it doesn’t quite reach the upper tier occupied by some of the market’s best real money slots.
In & Out Theme—Slipping Past Security for One Last Big Score
NetEnt places In & Out slot inside a dark museum after-hours. In fact, the entire scene is lit by moonlight pouring through the floor-to-ceiling windows, which I think fits the heist premise perfectly. Chloé has already broken in and is moving between display cases packed with valuable artefacts. More specifically, a glass case holding a jewel-encrusted tiara sits on one side of the screen, while an Egyptian sarcophagus stands guard on the other. The reels themselves also appear enclosed within a large glass showcase.
Everything from the dark blue colour palette to the polished floors reinforces the idea of a high-end burglary carried out under the cover of darkness. And when it comes to the audio, you’ve got a lively French ska soundtrack that plays throughout. It adds a distinctly Parisian flavour that contrasts nicely with the quiet, high-security museum setting.
In & Out skips traditional card symbols entirely and commits fully to the burglary concept. You’ll actually find everything from lock picks and grappling hooks to necklaces, rings, earrings, and tiaras.
Here’s a look at the payouts available at UK online casinos:
| Symbol | Payouts/Info |
 Gloves | 8 to 12+ = 0.1 to 1.5x the stake |
 Flashlight | 8 to 12+ = 0.1 to 1.5x the stake |
 Lock Picks | 8 to 12+ = 0.2 to 1.75x the stake |
 Crowbar | 8 to 12+ = 0.2 to 1.75x the stake |
 Grappling Hook | 8 to 12+ = 0.2 to 1.75x the stake |
 Necklace | 6 to 12+ = 0.5 to 3x the stake |
 Purple Gem Pendant | 6 to 12+ = 0.5 to 3x the stake |
 Emerald Ring | 6 to 12+ = 0.75 to 4x the stake |
 Red Gem Earrings | 6 to 12+ = 0.75 to 4x the stake |
 Diamond Tiara | 6 to 12+ = 1 to 5x the stake |
 Wild | Substitutes for all symbols except Bonus, Bomb, and Heist Mode symbols; Can contribute to multiple winning combinations simultaneously and appear anywhere on the reels |

In & Out Mobile Slot
In & Out handles the transition to mobile casinos without losing much of what makes the desktop version work. The highlighted tier positions are easy to distinguish, and the larger feature sequences don’t overwhelm the interface when Avalanches, Bombs, and Heist Mode effects start overlapping. I also found it fairly easy to keep track of which positions had progressed towards Bronze, Silver, Gold, or Diamond status on a smaller screen.
As for many other new slots, I would still favour landscape mode, largely because the grid can expand all the way to 8 reels by 7 rows. Once that starts happening, the extra horizontal space becomes quite useful for following the evolving layout and Heist Mode area.
In & Out Bonus Features
The feature set is where In & Out starts separating itself from a standard scatter-pay slot. Between expanding reels, tier upgrades, Heist Mode, multiple free-spin variants, and the Elevate shortcuts, there’s quite a lot happening here.
Avalanche™ Feature
Every winning combination triggers an Avalanche, and it clears the winning symbols before fresh ones fall into place. At the same time, any winning positions become highlighted and can be upgraded through Bronze, Silver, Gold, and Diamond tiers whenever they’re involved in future wins.
Expanding Reels
The Expanding Reels feature revolves around Bomb symbols. Whenever a Bomb lands, it explodes and removes adjacent (non-Wilds, scatters, and Chloé) symbols to create space for an Avalanche. If the Bomb lands on the outer edge of the grid, it also adds an extra reel or row in that direction before new symbols drop in.
Since the layout can grow from 6×5 to a maximum of 8 reels and 7 rows, much larger symbol clusters can form as the round develops. However, any extra reels and rows remain active for the rest of the round before the grid resets to its default 6×5 size on the next spin.
Heist Mode
Heist Mode is triggered when Chloé lands alongside at least one highlighted position after all Avalanches have finished. The highlighted positions become a hold-and-collect style feature with 3 starting spins, where you’re trying to build Coin values, unlock higher tiers, and create more Diamond positions before the spin counter reaches zero and the feature ends.
Heist Mode uses a tier-based value system, with Bronze Coins paying x0.5–x2, Silver x4–x10, Gold x15–x30, and Diamond rewards ranging from x50 up to x1,000. Also, Coins, Diamonds, and Multipliers are sticky and remain visible until Heist Mode ends.
The special symbols are:
- Multiplier symbols apply a random multiplier of x2, x3, x4, x5, or x10 to all Coins, Diamonds, and Collectors at the end of the feature.
- Upgrader symbols increase nearby positions by one tier. Bronze becomes Silver, Silver becomes Gold, and Gold becomes Diamond. They can also upgrade Bonus symbols into Super Bonus symbols.
- Burst symbols instantly convert random non-highlighted positions into highlighted positions of the same tier as the Burst symbol. This can even expand the playable Heist area.
- Blast occurs when an Upgrader and Burst appear together. Their effects combine, upgrading positions, expanding the Heist area, and adding Coin values to affected empty spaces.
- Extra Life symbols award an additional Heist Mode spin.
- Collector symbols gather the value of every Coin, Diamond, and existing Collector currently visible. The collected symbols disappear, while the Collector remains on the grid.
The feature ends when you either run out of spins or completely fill the Heist area with symbols.
Free Spins
Free Spins are triggered when 3 Bonus and/or Super Bonus symbols are present after all Avalanches have finished. The feature starts with 5 free spins, while each Super Bonus symbol in the triggering combination adds +1 extra starting spin.
Once inside the feature, all the main mechanics remain active, including Avalanches, Bombs, Expanding Reels, and Heist Mode. And the grid size and highlighted positions carry over from the triggering spin. This allows you to continue from an already-developed setup instead of starting fresh.
Super Free Spins always begin on the maximum grid size. During both Free Spins and Super Free Spins, landing 1 Bonus symbol awards +1 extra spin, while 2 Bonus symbols award +2 extra spins. Bonus symbols cannot be upgraded during the feature.
Elevate Feature (Not Available at UK Online Casinos)
Instead of waiting for a feature to trigger naturally, you can pay an increased stake to improve your chances of reaching a specific mechanic or jump directly into one. There are five options available:
- Bonus Hunt (1.5x bet, 96.04% RTP) – Increases the chances of triggering Free Spins.
- Guaranteed Chloé Symbol (5x bet, 96.09% RTP) – Places a Chloé symbol on every spin.
- Heist Mode ON (20x bet, 96.05% RTP) – Instantly starts Heist Mode with 3 highlighted Bronze positions already active.
- Free Spins (100x bet, 96.09% RTP) – Drops 3 Bonus symbols onto the reels and immediately triggers Free Spins.
- Super Free Spins (800x bet, 96.03% RTP) – Drops 3 Bonus symbols and starts Free Spins with the grid already expanded to its maximum size.
In & Out Verdict: Where Every Feature Pushes the Next One Forward
If you’re looking for a slot where the different mechanics constantly feed into one another, In & Out has plenty to offer. The expanding grid and tier progression system alone create a stronger sense of continuity than most scatter-pay releases, though some beginners may find the rules take a little longer to fully absorb.
In & Out manages to avoid becoming another forgettable crime slot. The Parisian museum setting, strong audio work, and above-average 96.08% RTP give it a solid foundation. And it goes without mentioning the 12,086x maximum win. It also helps that the game never feels visually cluttered despite how much is happening behind the scenes.
NetEnt has struck a nice balance between accessibility and depth, creating a slot that is easy enough to follow on the surface but rewards players who spend time understanding it. The museum-heist theme is handled with more personality than many modern crime releases, particularly thanks to Chloé and the late-night Paris backdrop. I highly appreciated the medium volatility profile, too.
