• 1×4 Expanding Wilds: These Wilds can appear on reels 2 through 5 during both the base game and the bonus rounds. They expand to cover an entire reel, significantly enhancing win potential by carrying multipliers that can reach up to 8x.
• 2×4 Fiery Wilds: Encounter these high-impact Wilds on reels 3 and 4, where they can expand to cover both reels. These special Wilds are potent, bringing with them substantial multipliers that can escalate to an impressive 64x, drastically increasing payout potential.
• Hook Symbols: When these land on the first and sixth reels, they trigger a symbol transformation. All high-paying symbols present on the corresponding row immediately convert into 1×1 Wilds, with the hook symbols themselves also transforming into the same symbol for enhanced winning combinations.
• Bonus Game: Trigger this multi-stage feature by landing three or more Scatter symbols on reels 2-5, awarding an initial six free spins, plus two for each additional Scatter. Before free spins begin, a puzzle respin bonus determines the minimum wild multiplier and can activate hook symbols. Completing the puzzle awards the maximum win.

Sanatorium Secrets’ 10,000x maximum win is a direct result of its features. Standard symbol wins set a baseline, but the ultimate payout comes when expanding wild multipliers, up to 64x, synergize with the unique puzzle respin bonus. Completing this puzzle in the pre-free spins round is crucial for the top prize.
