Cosmic Crystals Slot Overview
Cosmic Crystals is a sci-fi video slot from Iron Dog Studio, part of the 1×2 Network. It sends you into deep space, where glowing crystals float against a pink planetary haze and a jet-black sky. The colours are the main draw, and the action stays easy to follow.
The game plays on 5 reels and 3 rows with 50 fixed paylines. Its two headline features are expanding wilds and a Re-Spin feature that keeps the reels turning until you land a win. There are no scatters, bonus symbols or traditional free spins.

Iron Dog Studio announced Cosmic Crystals in June 2017 as one of the studio’s first six slots, when the 1×2 Network rebrand introduced the studio. We could not find a current official game page, so the betting figures, paytable and variance on this page come from our original review. Check the in-game help screen at your casino before you play.
Theme and Graphics
Cosmic Crystals lets you delve into the outer realms of space. The reels float over a deep black background, and a pink planetary haze gives the scene a soft glow. Stunning colours stand out against the dark, which makes the crystals look almost lit from within.
The look is clean rather than cluttered. Because the reels have only three rows, every symbol is easy to read, and wins are quick to spot.
Cosmic Crystals Symbols
The high-value symbols are crystals in pink, purple, blue, green and yellow. The lower values are the card ranks 10, J, Q, K and A.
| Symbol | 2 of a kind | 3 of a kind | 4 of a kind | 5 of a kind |
|---|---|---|---|---|
| Yellow crystal | 5x | 25x | 150x | 1,000x |
The Yellow Crystal is the best-paying crystal in the game. Multiples apply to your line bet, according to our original review. A pair is enough for a win with this symbol, which is unusual in a slot of this type.
Golden Crystal Wild
The wild is the Golden Crystal. It replaces every other symbol to help form winning combinations. There are no scatters or bonus symbols in this game, so the wild carries much of the action.
Cosmic Crystals Features
Expanding Wild Reels
When a Golden Crystal wild appears on reel 2, 3 or 4, it expands to fill the whole reel. A full reel of wilds can create wins across many of the 50 paylines at once. It is the most direct way to a big payout in the game.
Re-Spin Feature
The Re-Spin feature is unusual because there cannot be an unsuccessful spin. After a spin with no win, the feature activates and the reels keep spinning until at least one winning combination forms.
Wilds that land on reels 2, 3 or 4 lock into place until there is a win. That raises the chance that the next re-spin pays, and the locked wilds can expand as well.
Betting, Paylines and Variance
The game uses one coin per payline across all 50 lines. You choose the coin value, which our original review gave as $0.01 to $2.00. At the lowest value the minimum bet is $0.50 per spin, and at the highest the maximum is $100.00.
All 50 lines stay active, so the stake is simply the coin value multiplied by 50. A low coin value keeps each spin cheap and suits a long session.
Our original review rated Cosmic Crystals as a low variance slot. In plain terms, wins tend to arrive often and stay modest. The Re-Spin feature supports that style, since it prevents dead spins. Our guide to RTP and online slots explains how return and variance fit together. We could not confirm an RTP figure from the studio, so check the help screen at your casino.
Playing Cosmic Crystals on Mobile
The game is built to work on mobile as well as desktop. You tap and swipe your way through the action, and the interface is user-friendly. You can also set up Autoplay for non-stop spins.
Most casinos run the slot in a mobile browser, so you do not need to download an app. The clean layout and big crystals suit a smaller screen well.
How to Play Cosmic Crystals
- Open the game and check the paytable on the help screen.
- Choose your coin value. The game uses one coin per payline.
- Press Spin, or set Autoplay for a fixed number of rounds.
- Watch reels 2, 3 and 4 for Golden Crystal wilds.
- Let the Re-Spin feature run when a spin does not win.
- Stop when you reach your budget or time limit.
Who Is It For?
Cosmic Crystals suits players who like simple, colourful slots with steady action. The Re-Spin feature makes it friendly to beginners, because a spin never has to end empty. It also fits players who prefer a low variance game and small, regular wins.
Bonus hunters may find it too plain. With no scatters and no free spins, the game relies on wilds and re-spins alone.
Tips for Playing
No tip can change the odds, since every spin is random. A few habits can make the session more enjoyable.
- Pick a coin value that gives you a comfortable number of spins.
- Use the demo mode first, if your casino offers one.
- Set a budget and a time limit before you start, and stick to them.
What Makes The Re-Spin Feature Different
Most slots treat a losing spin as a loss and move on. Cosmic Crystals does the opposite. It keeps the reels turning until something pays, so a spin never has to end without a win.
That does not mean every spin makes a profit. A small win on a 50-line bet can still be worth less than the stake. What it does mean is that the base game feels smoother, with fewer long dry runs.
The locked wilds are the second half of the idea. Once a Golden Crystal lands on reel 2, 3 or 4, it can stay in place while the re-spins continue. As a result, the feature can build a strong position before the reels stop.
How It Compares With Other Space Slots
Many space slots lean on big bonus rounds and high variance. Cosmic Crystals goes in a different direction. It keeps the rules short, uses a clean 5×3 grid and puts its weight on two simple features.
That makes it a good first space slot for new players. Those who want a longer feature list will find more in other games, but this one is easy to learn in a few spins.
Pros and Cons
| Pros | Cons |
|---|---|
| Bright, colourful space theme | No scatters or free spins |
| Re-Spin feature prevents dead spins | Low variance, so big wins are less likely |
| Expanding wilds on reels 2, 3 and 4 | No current official specs found |
| Pays for 2 of a kind on the top crystal | Few bonus features |
