How the Game Plays

Alien Digger takes players on an intergalactic mining expedition to a desolate planet filled with precious gems and gold. Developed by Onlyplay, the game features a standard 5x3 grid set against a cosmic backdrop of alien rock formations and starry skies. Symbols include essential mining gear like oxygen tanks, energy sources, helmets, and dynamite bundles, alongside higher-paying gold nuggets and gemstones. The Alien Miner serves as the Wild, substituting for all regular symbols to help complete winning lines across the 10 fixed paylines.

Free Spins Explained

The main feature is triggered by landing three or more Space Drill Scatter symbols anywhere on the reels, awarding an initial 10 free spins. This round can be retriggered if another three Scatters appear during the feature, extending the session.

Sticky Winning Symbols Feature

The standout mechanic in this slot occurs during the free spins round. Every time a winning combination is formed, the contributing symbols become "Sticky" and remain locked in place for the remainder of the bonus session. As subsequent spins occur, any additional matching symbols that land and contribute to the existing wins also lock into place. This allows players to build massive winning clusters or full-screen combinations that pay out on every remaining spin of the bonus round.
