Great Reef vs Release the Bison
- Both titles are built on the same format family: Fixed paylines. Differences between them therefore come from tuning, not from structure.
- Published RTP: 96.64% against 96.54% — Great Reef is 0.10 points higher. RTP is a long-run theoretical figure, not a session forecast.
- Both cap out at roughly the same place: 3,000× and 3,000×.
- Volatility cannot be compared: Great Reef does not publish a rating.
- Worth noticing: the higher RTP and the higher win cap sit on opposite sides. Great Reef returns more in theory over the long run, while Release the Bison reaches further at its ceiling. The two numbers answer different questions.
Great Reef vs Mermaids Millions
- Both titles are built on the same format family: Fixed paylines. Differences between them therefore come from tuning, not from structure.

- Volatility cannot be compared: Great Reef does not publish a rating.
