How the Game Plays

Solar Spins transports players to the heart of a vibrant solar system, featuring a celestial 5x3 grid set against a deep-space backdrop filled with drifting asteroids. The game utilizes 20 fixed paylines where wins are formed by landing matching symbols from left to right. High-value symbols are represented by various planets, including detailed renderings of Earth, Jupiter, Saturn, and Mars, while lower-value payouts are awarded through colorful royal card suits. An Asteroid Wild symbol substitutes for standard paytable symbols to help bridge gaps in winning sequences.

Free Spins Explained

The Free Spins feature is initiated when three or more Blackhole Scatter symbols appear simultaneously on the reels. This transition into the bonus round offers a set number of spins—typically between 5 and 9—where the cosmic environment intensifies. This mode provides a path to significant payouts without additional wagers, focusing the action on higher-tier planetary symbols and increased opportunities to trigger the secondary bonus feature.

Hold and Win Bonus Explained

The core attraction of this slot is the Hold and Win feature, triggered by landing six or more Sun Bonus symbols in a single spin. Once active, the triggering Sun symbols lock into place, and the player is granted three respins on a special grid where only bonus symbols or blanks can land. Each new Sun symbol that appears resets the respin counter to three. These symbols carry specific credit values or represent one of the fixed jackpots—Mini, Minor, Major, or Grand. The round concludes when the respins are exhausted or the entire grid is filled, at which point all accumulated values are tallied.
