Verdict
CASUALPlayer Fit Spectrum
Casual
CasualBalancedHardcore
Based on the 300SPINS™ test, Dolphin's Pearl may suit casual players who prefer an easygoing rhythm over intense action.
In addition, total payouts were not concentrated in a few large wins in this test. This may suit players who prefer results built from other wins rather than a handful of large payouts.
About 300SPINS™
Every 300SPINS™ review starts with hands-on play: we manually play each slot, record the results and analyze the session data ourselves. Every test follows the same protocol: 300 paid spins in one continuous session, a fixed base bet, and no bonus buys or optional bet enhancements. Naturally triggered free spins and bonus rounds are included in the results. This consistent setup lets us compare win frequency, payout multipliers and feature activity across games. The analysis describes the recorded session, rather than the game’s complete long-term payout behavior.

About RTP Deviation
This analysis does not evaluate the slot's theoretical RTP or long-run return. It only measures how far the total return recorded in this 300-spin session was from the average of other eligible 300SPINS™ reviews conducted with the same method. A larger deviation may suggest a wider range of outcomes, but it does not establish the slot's actual volatility or predict future results.

Highlight Features
Retrigger
A Retrigger means winning additional free spins by landing scatter symbols again during a free spins bonus round. Furthermore, some slots adopt an 'unlimited retrigger' system, which means there is no limit to the number of times it can re-trigger. In theory, if luck is on your side, the free spins can continue indefinitely, making it one of the most powerful features a slot can have.
Multiplier Wild
A Multiplier Wild is a powerful hybrid wild that combines the basic ability of a wild to substitute for other symbols with a multiplier feature that amplifies the payout itself. The core of this feature is not just about connecting a broken combination, but about multiplying the value of the completed winning combination several times over, turning an ordinary win into a high-payout moment.
