Crystal Waters is a 5-reel, 3-row RealTime Gaming slot set just off a tropical island, with dolphins, turtles, seahorses and conch shells swimming across 20 paylines above a backdrop of clear water and sandy shores. Like several RTG classics, casinos can select from three published RTP tiers for this title.
| Provider | RTG (RealTime Gaming) |
| RTP | Configurable: 91%, 95% or 97.5% depending on casino |
| Reels / Rows | 5 / 3 |
| Paylines | 20 |
A Substitute Dolphin symbol can appear on the 2nd and 4th reels, swapping itself into whatever position best completes a winning combination — functioning as a targeted wild rather than a purely random one. The free spins round adds an additional wild symbol into the mix, and a randomly triggered progressive jackpot sits above the regular paytable. Because RTG publishes Crystal Waters with three selectable RTP settings (91%, 95%, or 97.5%), the exact payback a player experiences depends on which configuration the licensed casino has chosen.
Pros
- Substitute Dolphin actively completes winning combinations rather than landing randomly
- Free spins round adds an extra wild symbol into play
- Randomly triggered progressive jackpot for extra long-shot value
- Highest configurable RTP tier (97.5%) is well above average
Cons
- RTP varies by casino, from as low as 91% up to 97.5%, so it’s worth checking which tier is live
- Volatility rating and max-win figure are not consistently documented for this title
- Classic underwater theme is fairly generic next to newer aquatic slots
