Undine’s Deep has an RTP equal to 96% — which is medium. Any return-to-player percentage at or below the 94% mark falls into the 'low' category when compared with other slots. Anything between 94-96.5% is labeled 'medium,' and any RTP above 96.5% measures as 'high.'

The return-to-player percentages might not look very far apart initially, but they certainly are. Permit me to make it clear.

While Return To Player is where the focus usually lies, the actual percentage that isn't returned to you which is what truly counts — labeled as the House Edge.

For Undine’s Deep, you calculate the House Edge using 100% - 96% = 4%. 4% amounts to the casino’s advantage for this particular game. Stated differently, the casino will keep this portion from what you wager as its share.

Let’s assume you’re betting $1 per spin, and you put $100 into your account with the casino. Before you’re out of cash, you can expect to get 2882 rounds of play on Sweet Bonanza 1000.

The math of this is $100 divided by 3.47% equals 2882 total spins.
