Book of Sun: Multi Chance Slot Review — 3 Oaks Gaming

Book of Sun: Multi Chance is a video slot from 3 Oaks Gaming, released on 15 May 2019, built on a 5×3 reel layout with 10 paylines. It belongs to the book-mechanic family — a symbol that expands across a reel and can trigger free spins — and carries a theoretical RTP of 95.4% with a high volatility profile and a max win of x10000 the bet. Stakes run from 0.2 to 30.0 per spin, which keeps the entry cost low while the payout curve stays uneven.

Core Gameplay Experience

The grid is compact: five reels, three rows, 10 fixed paylines. That layout limits the number of ways a symbol combination can land, which is one reason the swings feel sharper than on slots with 20+ lines — fewer paths to a win means each spin either connects cleanly or misses outright.

Visually the reels sit inside an ancient Egyptian setting rendered in browns, oranges and sandy tones, with a scarab, hieroglyphs and magic-lantern lighting framing the book symbol at the centre of the design. The theme is a straight continuation of the Ancient & Historical slot tradition that Ancient & Historical themed slots cover on this site, and it plays a functional role here: the central book is both the visual anchor and the trigger for the game’s main feature.

Base-game rounds move quickly between spins, and because paylines are capped at 10, most rounds resolve without a payline hit — the volatility budget is spent on the free spins round rather than smoothed out over frequent small wins.

Features and Mechanics

The wild symbol substitutes for other paying symbols to complete lines that would otherwise miss, a standard function that raises the base-game hit rate slightly without changing the payout structure. The scatter symbol works independently of paylines and is the entry point into the free spins round, following the book-mechanic pattern shared with the wider Book of Ra-style genre.

Once free spins start, an expanding symbol is selected and grows to fill entire reels for the remainder of the round, which is what produces the larger multi-symbol combinations the slot is named for. The extra free spins feature adds further spins on top of the initial award during that round, extending the window in which the expanding symbol can pay out repeatedly before the feature ends.

RTP, Volatility and Payout Model

Book of Sun: Multi Chance runs a 95.4% RTP against a high volatility rating, meaning the design favours infrequent but larger payouts over steady small returns. In practice that means base-game spins without the expanding-symbol free spins round tend to return little, while the free spins round itself carries most of the game’s payout weight, including the path to the x10000 ceiling.

A 95.4% RTP sits in the 28th percentile of the 4,445 slots in our catalog with a published RTP, against a catalog median of 96% — placing this title below most of the field on that single metric. High volatility is a common profile choice, shared by 62% of the 4,737 slots in our catalog, so this game is not an outlier on risk, only on the return figure itself. The x10000 max win, by contrast, lands in the 77th percentile of the 3,441 slots with a published max win figure, well above the catalog median of 2,500x.

Similar 3 Oaks Gaming Slots — Comparison

Among 3 Oaks Gaming titles matched by high volatility and up to 10 paylines, Book of Sun: Multi Chance ranks 4th of 5 by RTP, ahead only of Lion Coins on that measure. Players who prioritise return figures over theme have Book of Sun Choice and 3 Egypt Chests as the closer alternatives within the same studio; Lion Coins trades RTP for fewer paylines and a different bonus structure.

Similar Book of Ra Mechanic Slots from Other Studios

Across this book-mechanic cluster, Book of Sun: Multi Chance and Antica Roma sit closest on RTP among the compared titles, while Stunning Crown breaks from the pattern with a medium volatility rating and the highest RTP of these four slots. Golden Nile publishes the lowest max win of the titles listed here at x3000, which is a fraction of what Book of Sun: Multi Chance can reach.
