Space Coins by 3 Oaks is a retro-inspired slot that combines classic 3-reel gameplay with a cosmic setting and a Hold and Win bonus feature. The game offers a compact 3×3 layout, 5 paylines, sticky Collect symbols, jackpot rewards, and a maximum payout of up to 3,000x the total bet. It is designed for players who enjoy simple reel action in the base game but still want access to feature-driven win potential.
Set against a deep-space background filled with glowing stars, floating debris, and nebula effects, Space Coins creates a playful sci-fi atmosphere while keeping the gameplay straightforward. The slot mixes traditional symbols like bells, BARs, gems, and lucky sevens with a bonus system built around collecting cash prizes and jackpots during respins.
Overview of Space Coins
Space Coins is part of the wider Hold and Win-style Coin collection from 3 Oaks, this time shifting the action away from familiar land-based themes and into a futuristic cosmic world. Unlike larger modern video slots, this release keeps things intentionally compact with a 3×3 reel set and 5 active paylines, offering a more classic slot structure with a modern bonus layer on top.
The slot is aimed at players who appreciate quick spins, simple reel mechanics, and a bonus game that can produce stronger payouts than the base game. The soundtrack leans into a retro synth style, which fits the space theme well and gives the game a slightly nostalgic feel.
Bet Range, Volatility and Max Win
Players can set their bets from €0.20 to €70 per spin, making the game accessible to both lower-stake players and those looking for higher-risk sessions. Space Coins is described as a medium to high volatility slot, meaning smaller wins may appear in the base game, while bigger rewards are more likely to come from the bonus feature.
The RTP has not been officially disclosed, but the maximum advertised payout reaches up to 3,000x the stake. This top prize is possible during the bonus round when multiple Collect symbols are active at the same time.
Symbols and Base Game Payouts
The symbol set in Space Coins includes a familiar mix of classic slot imagery and colorful gem icons. Wins are formed by landing 3 matching symbols across one of the 5 paylines. The highest-paying regular symbol is the red triple 7, which also functions as the Wild.
The Wild can substitute for all standard pay symbols, helping complete winning combinations across the reels. Three Wilds award the top standard payout in the base game, worth 50x the bet.
Other base game symbols include bells, BARs, Xs, and several types of gem pairs. The purple and orange gem pairs are among the stronger paying gem symbols, rewarding 16x the stake for 3 matching icons. The remaining red, green, and blue gem pairs pay 4x the bet for the same result. Lower-value symbols such as Xs pay more modest prizes, keeping the base game focused on regular top-up wins rather than huge standalone payouts.
Base Game Experience
The main game in Space Coins is simple and fast. There are no extra reel modifiers or expanding features during standard spins, aside from the Wild symbol. This keeps the action clear and direct, with the primary goal being to land the right symbol combination to unlock the bonus round.
Players can also choose between 3 spin speed settings, which is useful for those who prefer a faster playing style. Since the main attraction of the slot is the bonus feature, the higher speed option can make the overall experience feel much more dynamic.
Space Coins Bonus Game
The highlight of the slot is the Space Coins Bonus Game. This feature starts when at least 1 Collect symbol lands together with at least 1 Bonus or Jackpot symbol on the same base game spin. Before the respins begin, the triggering Collect symbol or symbols immediately gather the value of all visible Bonus and Jackpot symbols on the reels.
Once the feature is activated, the player receives 3 respins. Collect symbols can only appear on reel 2, and they remain sticky throughout the entire round. Bonus and Jackpot symbols appear only on reels 1 and 3. Every time a new Bonus or Jackpot symbol lands and is collected, the respin counter resets back to 3. The feature ends after 3 consecutive respins without any new collecting action.
Collect Symbols and Prize Values
The Collect symbols are what make the bonus round especially interesting. Up to 3 Collect symbols can be active at once, and each of them gathers every visible Bonus and Jackpot symbol on the side reels whenever a collection occurs. This creates the potential for much bigger totals, especially if several Collect symbols are present together.
Regular Bonus symbols come with random prize values ranging from 1x to 15x the bet. These values may seem modest at first, but they can build quickly when several symbols are collected repeatedly during the same feature.
Jackpot Values
In addition to standard Bonus symbols, the feature can also award fixed jackpot prizes. These jackpot symbols carry the following values:
- Mini Jackpot – 25x the bet
- Minor Jackpot – 50x the bet
- Major Jackpot – 150x the bet
- Grand Jackpot – 1,000x the bet
If multiple Collect symbols are active when jackpot symbols land, the total bonus value can increase dramatically. This is where the game’s top reward potential comes from, with the maximum win reaching 3,000x the stake in the best-case scenario.
Bonus Buy Options
For players in eligible markets, Space Coins includes a Bonus Buy feature. This option allows direct access to the main bonus round without waiting for a natural trigger during the base game. Two purchase choices are available:
- Bonus Game – 75x the bet – awards 1, 2, or 3 triggering Collect symbols
- Super Bonus Game – 150x the bet – guarantees 3 triggering Collect symbols
The regular Bonus Buy gives a random number of Collect symbols at the start, while the Super Bonus version ensures the strongest possible setup from the beginning. This makes the second option much more aggressive, but also significantly more expensive.
Theme and Design
Visually, Space Coins combines retro slot elements with a sci-fi setting. The reels sit in front of a deep blue cosmic background filled with glowing space effects, while a mysterious energy sphere surrounded by coins hovers above the casino games area. The jackpots are displayed around it, keeping the potential prizes constantly in view.
The classic symbols, including lucky sevens and bells, give the slot a vintage touch, while the gem icons and cosmic background add enough personality to keep it from feeling too plain. The electronic soundtrack supports the theme nicely and gives the whole game a light arcade-like energy.
Final Verdict
Space Coins is a compact slot that successfully combines old-school reel action with a feature-led bonus system. The 3×3 format and 5 paylines make it easy to understand, while the Hold and Win-style mechanic adds more depth once the bonus round begins. The ability to land up to 3 sticky Collect symbols makes the feature the clear highlight of the game.
Although the maximum payout of 3,000x is not massive compared to some modern high-volatility slots, it is still respectable for a traditional-style 3-reel release. Players who enjoy classic symbols, quick gameplay, and jackpot-based bonus rounds may find Space Coins a fun and worthwhile choice.
