How to cite

Slot Summary

Dolphins that double completed combinations bring a sharper edge to Crystal Waters' calm reef setting. Realtime Gaming pairs the underwater presentation with high-volatility play, so the gentle mood is no guide to the size or spacing of returns. A second substituting fish arrives during free spins, increasing the importance of special-symbol combinations.

How It Plays

Regular wins form across the active paylines on a 5x3 reel set. The game offers 20 adjustable lines, allowing the active line selection to change before a spin.

Dolphin wilds appear on the second and fourth reels. They replace ordinary paying symbols but cannot replace the Yacht, whose separate scatter role controls entry to free spins.

Bonus & Free Spins

Three or more Yacht scatters award 15 free spins. During the round, a Bonus Fish can appear on the third reel and substitute for symbols except the Yacht. Its payout factor can be 2x, 4x, or 8x.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (97.50%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
