    Not bad, but the 10 betways made it harder to hit big wins. Got lucky with the free spins and landed a 500x on my bet after 5 wilds triggered the bonus. It's fun, but the unknown volatility makes it a bit unpredictable—might give it another go, though.

    Got some decent wins on Book of Unseen. The wild symbol triggered the free spins bonus for me, and I got 6 expanding symbols after 4 wilds hit. Ended up with a 300x multiplier and made a nice profit. Would’ve been perfect if there were multipliers in the base game too.
