Developer Space Coins by 3 Oaks Gaming is a retro-style slot built on a 3x3 reel set with 5 paylines and medium-high volatility. Released in May 2025, the game uses a space theme with coin-collecting features, shooting stars and a Hold & Win bonus round. Bet options range from 0.2 to 60, and the demo version is available for players who want to play for free and practice before playing for real money.
The main bonus game starts when bonus symbols land on reels one and three, alongside Blue Orb collect symbols on the middle reel. Once triggered, the feature gives three respins on fresh reels containing only bonus and collect symbols. Each new symbol resets the respin counter, while collect symbols remain in place and gather values from bonus symbols, including Mini, Minor, Major and Grand Jackpot prizes.
Space Coins also offers two alternative ways to activate the bonus round: a metre that tracks bonus and collect symbols, and a Lucky Spin mechanic. Players can also buy access to the bonus or Super Bonus, where all three collect symbols are active from the start. A Grand Jackpot symbol can reach x1,000, with the chance to triple it to x3,000 the bet when the full collection is completed.
