Reptoids Slot Overview
Reptoids is a quirky sci-fi slot from Yggdrasil. It is set in the 1960s, in a world where shape-shifting aliens hide among us. Nobody can be trusted, and the government is trying to round them all up.
The game has five reels, three rows and 20 paylines. Its star feature is the Repto Detector, which scans the reels on every spin and turns symbols into Wilds. Free spins, sticky Wilds and big scatter prizes complete the package.
A note on sources. We could not find Reptoids on Yggdrasil’s current website or in its public games catalogue. That does not prove the game is gone, because the catalogue may not list every title. As a result, every game figure below comes from our original review and is marked that way. Check the in-game rules at your casino.

The Story And Look
Reptoids plays like a 1960s B-movie. The story says humans are turning into aliens known as Reptoids, who then try to take over the world. They hide among us, so you cannot trust anyone.
Our original review praised the stunning 3D visual animations. The artwork leans into the paranoia of the era.
It is a refreshing change from the usual fruit and treasure themes. If you like campy sci-fi, you will probably enjoy it.
Why Conspiracy Themes Work In Slots
Alien takeover stories have been popular for decades. They suit a slot because the idea is easy to grasp. Someone among the symbols is not what they seem, and your job is to spot them.
Reptoids turns that idea into game play. The Detector literally scans for hidden aliens. This ties the theme to the feature, which is what the best slots do.
It also gives the game a talking point. Few other slots ask you to hunt for shape-shifters. That helps it stand out in a long list of Yggdrasil titles.
How The Detector Changes Each Spin
Most slots follow a fixed pattern. You spin, the reels stop and the game pays any wins. In Reptoids, the Detector adds a step. Before the result is final, a random frame decides which symbols may change.
This means two spins with the same symbols can end differently. One may land the frame on a winning line. The other may miss it. That small twist keeps the base game lively.
In the free spins, the effect grows. Sticky Wilds stay put, so the Detector has more to work with on each new spin.
Symbols
The symbols tell the story. You will see Presidents, Police Officers, a Politician, a General, a Nurse, a Scientist and a Reporter. Military medals in nickel, bronze, silver and gold make up the lower values.
Aliens and Reptoids sit among the top symbols. The Gold Coin is the Scatter.
| Symbol | Value | Role |
|---|---|---|
| Military medals | Low | Nickel, bronze, silver and gold |
| Human characters | Medium to high | President, Police Officer, Politician, General, Nurse, Scientist, Reporter |
| Aliens | High | Better line wins |
| Reptoid | Wild | Replaces all regular symbols except the Scatter |
| Gold Coin | Scatter | Pays 10x to 5,000x and links to free spins |
Betting Options
Coin values run from 0.05 to 5.00. That gives a bet range of 0.10 to 100.00 per spin in our original review.
The range suits both small and bigger budgets. Players on a tight budget can enjoy long sessions at the low end.
Wild Symbol: The Reptoid
The Reptoid is the Wild. It substitutes for every regular symbol except the Scatter. In the right moment, it can complete a payline that would otherwise miss.
Scatter Symbol: The Gold Coin
The Gold Coin Scatter appears only in the base game. Land two or more across a payline and you win 10, 100, 1,000 or 5,000 times your stake. The size of the prize depends on how many land.
The Scatter also plays a part in the free spins, as we explain below.
The Repto Detector Feature
This is the signature feature. A Detector frame moves to a random position on every spin in the base game. Any symbols that land inside the frame are scanned.
Symbols that land in the Detector turn into Wilds. Uncovered Reptoids become sticky Wilds for the duration of the feature.
It is a neat idea. You never know where the frame will land, so each spin has a little suspense. When it lines up with the right symbols, the win potential can climb quickly.
Free Spins
The free spins start when the Scatter lands in the Detector. You receive 7 free spins.
There are bonuses on top. If you uncover all the Reptoids, you win an extra 6 free spins. For every 2 Reptoids detected, 2 extra spins are awarded.
| Trigger | Reward (original review) |
|---|---|
| Scatter lands in the Detector | 7 free spins |
| All Reptoids uncovered | 6 extra free spins |
| Every 2 Reptoids detected | 2 extra free spins |
Sticky Wilds make the free spins the most exciting part of the game. They stay in place, so wins can build over several spins.
Auto Spin
The Auto Spin tool spins the reels without interruption for a set number of times. It is handy for a hands-off session. Use the stop options if your casino offers them, and keep an eye on your balance.
RTP And Volatility
The RTP in our original review is 96.1%. That is a touch above the average for online slots. Our guide to RTP and online slots explains the figure.
RTP is a long-term average over millions of spins. It does not predict a single session. The Detector and the sticky Wilds can cause swings, so expect some quiet spells and some lively ones.
Playing On Mobile
Yggdrasil builds its games for desktop and mobile. Reptoids is listed for both in our site data. The 3D artwork should scale well, but check how it runs on your device.
Tips For Reptoids
No tip changes the odds, because every spin is random. A few habits can still help.
Try the demo first, if your casino offers one. It lets you watch the Detector in action without risking money.
Pick a stake that lets you play for a while. The best moments come from the free spins, and you need enough spins to reach them.
Finally, set a budget and a time limit before you begin.
Pros And Cons
| Pros | Cons |

Who Is Reptoids For?
This slot suits players who want a fun theme and a feature they can watch. If you like sticky Wilds and campy sci-fi, you should enjoy it.
Casual players will find the rules simple. The Detector does the hard work for you, so there is little to learn. New players can pick up the game in a few spins, which makes it a friendly way to try Yggdrasil for the first time.
If you prefer very high volatility or giant jackpots, you may want to look elsewhere.
