SlotRanker Score: 57 — Blue Dolphin by Amatic

Slot Summary

Blue Dolphin fills a narrow slot niche: a Sea-themed game with 5 fixed paylines and one plainly signposted Bonus Game. Amatic keeps the base format compact, using the dolphin as a Wild Symbol and the Scatter Symbol as the gateway to 15 bonus spins. During that round, every win carries a 3x Multiplier and the feature can retrigger, giving an otherwise traditional video slot a distinct second phase.

How It Plays

Blue Dolphin uses a 5x3 layout and 5 fixed paylines, keeping the base loop centered on a small number of easily followed winning paths.

The dolphin Wild Symbol substitutes for ordinary symbols but not the Scatter Symbol. This gives it a straightforward line-completion role before the Bonus Game begins.

Theme & Atmosphere

The Sea setting and dolphin figure place the Animals and Fish themes at the center, with underwater imagery supplying the game's entire narrative context.

Rather than separating the mascot from the rules, the dolphin also functions as the Wild Symbol. The central theme figure therefore remains relevant during ordinary spins.

Features & Win Potential

The Wild Symbol helps complete payline combinations, while the Scatter Symbol operates independently of line positions and opens the Bonus Game.

Medium volatility accompanies a narrow mechanic set. The Multiplier is reserved for bonus spins, creating a clear distinction between base-game wins and feature wins.

Bonus & Free Spins

Three, 4, or 5 Scatter Symbols award 15 bonus spins. Every win during the feature receives a 3x Multiplier, and another qualifying Scatter combination retriggers it.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (95.30%), 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.
