SlotRanker Score: 61 — Moon Sisters by 3 Oaks

How to cite

Slot Summary

Landing six Moon symbols is the decisive event in Moon Sisters, because it clears the remaining positions and starts a Hold and Win sequence with the triggering values locked. 3 Oaks places that mechanic inside an Asia-inspired story about two sisters connected to the Moon. Each new symbol resets the available respins, while special Moon symbols and a full grid provide the routes toward its fixed jackpots and x1000.00 ceiling.

How It Plays

The base game runs across five reels and twenty-five fixed lines. Moon symbols carry individual values and serve as the route into the main bonus.

Outside the feature, ordinary line combinations provide the regular cycle. The Moon symbols matter differently because collecting enough of them changes the screen into a locking respin format.

Theme & Atmosphere

Two mysterious sisters guide the Asia-inspired setting, with the Moon presented as the source of their connection and the game's principal symbol.

Flowers, butterflies and a restrained Luxury treatment soften the Treasure theme, creating a calm surface for a feature centered on filling every available position.

Features & Win Potential

The Hold and Win feature locks every triggering Bonus symbol, clears the remaining positions and starts a sequence of three Respins.

Sticky Moon symbols carry values, while special symbols can display fixed Mini or Major Jackpot awards. Filling the entire grid produces the Grand Jackpot route.

Bonus & Free Spins

Six Moon Bonus symbols start Hold and Win. Each new Moon remains fixed and resets the three-respin counter, so every landing extends the attempt to fill the grid.

Special Moon symbols may carry fixed jackpots during the Bonus Game. Completing every position awards the Grand Jackpot at x1000.00 of the wager.

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 (95.00%), 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.
