Book of Sun: Multichance Slot Review

The provider identifies the Book as both Scatter and Wild. The Free Spins explanation below focuses on the Book's trigger role and the selected symbols, without adding unlisted substitution exceptions or payout thresholds.

Three Book Scatters start twelve Free Spins. At entry, the player chooses one symbol to serve as the expanding symbol for the feature.

That initial selection establishes the first active expanding symbol. The provider's saved gameplay frames show the active-symbol strip above the reels, giving the player a way to distinguish progression from the ordinary symbol set.

The selected expanding symbol pays independently of the normal payline rules during the feature. That makes it different from simply landing an ordinary ten-line combination in the base game.

The retained frames show expanded symbols occupying reel columns and their corresponding winning display. The product overview does not specify a complete per-symbol expansion threshold, so no missing activation count is invented.

Landing another three Scatters during Free Spins retriggers the feature and unlocks an additional expanding symbol. This process can continue until all nine expanding symbols are active.

The important progression is the growing set of eligible symbols. A retrigger is not just more time on the same initial setup; it can change which symbols participate in the expanding-symbol mechanic.

The saved examples display the feature's spin progress and several icons in the active-symbol strip. These are illustrations of particular bonus states, not evidence that every feature will reach the same stage.

The overview specifies twelve spins at initial entry but does not separately state the added-spin amount for every retrigger or a total game cap. The illustrated cash stake likewise should not be interpreted as the full available betting range.
