Inside the game

How Moon Sisters works

Moons replace ordinary line combinations

Moons replace ordinary line combinations

The base-game frames show themed symbols, card ranks and Wilds. In Hold & Win, the useful information is instead printed on the Moon symbols: either an ordinary money value or a named jackpot award.

Six Moons and three initial respins

Six Moon Bonus Symbols start Hold & Win. The triggering Moons remain locked, the other positions clear, and the game awards three initial respins.

That clearing step separates the collection feature from an ordinary line win. Empty cells become the positions where further Moons can land, rather than places waiting to form a normal symbol combination.

New arrivals stay and reset the counter

Every new Moon locks into position and resets the respin count. The retained provider frame shows both the remaining attempts and the unfilled cells, so progress on the board can be read separately from the counter.

The saved description establishes this reset loop, but does not specify an additional hard-cap termination rule. A nearly complete grid should not be interpreted as a guarantee that the remaining cells will fill.

Mini and Major Moon symbols

Special Moons may carry Mini or Major jackpot awards instead of an ordinary value. These are named prize symbols within the same collection feature, not a separate set of paylines.

The bar above the provider board displays the jackpot amounts at the illustrated stake. Those cash amounts describe the example configuration and should not be promoted to universal fixed-currency prizes or a betting-range specification.

A full grid and the Grand target

Filling the grid with Moon symbols is the published target for the Grand jackpot of 1,000× the wager. A full-board provider frame illustrates all fifteen positions occupied.

The Grand is a defined bonus award, not a statement about typical payouts or an overall game cap. The retained overview focuses on Hold & Win and does not provide enough information to make additional Free Spins, Bonus Buy or exact stake-range claims.

04 / The SlotsCollector take

Verdict

Moon Sisters keeps the central objective easy to follow: collect more Moon values while the counter can still reset.

The partial and completed boards explain the feature more clearly than a large win celebration. This is a useful fit for players who prefer one visible collection loop to several layers of unrelated modes.
