Book of Sun: Multi Chance (3 Oaks Gaming (Booongo)) – Review & Demo Play

Book of Sun: Multi Chance - Game Review

I’ve put plenty through Book of Sun: Multi Chance, and for me it’s a great release with popular gameplay and great graphics. It’s a 5x3 with 10 lines, Average volatility and 95.72% RTP, topped by an x10000 Godlike Win. The balanced math model keeps the ride engaging, and the base game is never dull. New Book of Sun is saying that 10 lines is enough to get a SuperMegaBigWin, and when wilds and scatters land, it goes to a whole new level.

Features in Book of Sun: Multi Chance

The Book symbol pulls double duty as wild and scatter, setting up the bonus when 3+ land. Don’t even think to stop if you dare triggering the bonus game, because the signature mechanic shines here. A special expanding symbol takes centre stage, paying on any position during free spins, and it can cover reels for chunky line hits. This is the classic 'Book of ...' flavour, but with a twist that adds momentum as the feature develops.

Each time you encounter 3+ Books of Sun during the bonus, a new expanding symbol is added to a line of your wealth destiny. I love how the feature snowballs: retriggers stack more special symbols, opening more routes for wins across the 10 lines. Expanding symbols don’t need to be adjacent when active, so even scattered hits can pay. That extra freedom raises the ceiling and keeps the session lively when the books keep coming.

The headline hook is Nine Sacred Keys to Wealth: up to 9 special expanding symbols can be active if you keep retriggering. That’s where the slot shows its teeth and why the x10000 potential makes sense. On those rare streaks, reels fill, counts climb, and the screen can look mad with premiums. It’s volatile, but that rolling accumulation of expanders is the charm that differentiates Multi Chance from a standard book outing.

Book of Sun: Multi Chance Symbols and Paytable

Paytable numbers are straight from the series style. The top premium pays x500 for five, x100 for four, x10 for three, and x1 for two. The next band hits x200/x40/x4/x0.5, while two mid-tier figures return x75/x10/x3/x0.5. Lows sit at x15/x4/x0.5 and x10/x2.5/x0.5 for five/four/three. Scatter pays are x200, x20, x2 for five, four, three books. It’s a clean ladder that mirrors the high-ceiling, swingy nature. Payouts are expressed as multiples of the bet, which suits the punchy feature-driven profile.

During free spins, the chosen expanding symbols pay on any line and can stretch to cover reels after wins are calculated. With more expanders activated by retriggers, coverage improves and even mixed setups can deliver. In the base game, the Book stands in for regular symbols to complete lines, and its scatter pay helps seed the bonus. It’s a simple table to read, yet it supports that x10000 chase nicely.

Base Game in Book of Sun: Multi Chance

I rate the base as engaging even when no feature gets activated. With 5 reels and 10 betways, line hits pop often enough to keep the balance circulating, and wild books can patch awkward gaps. When scatters tease, the tempo lifts, and once the books land in threes or more, the slot moves to a new gear. It plays like a balanced package that can swing, which suits a session where I’m aiming for feature streaks.

Win Potential in Book of Sun: Multi Chance

Stats are clear, 95.72% RTP, Average volatility, and a max win of x10000. That mix feels fair for a book-style machine that leans on expanding symbols and retriggers. The math model is pretty balanced for everyday play, though it can throw considerable swings when the feature dries up. I treat it as a chase with measured stakes, letting the base game do the heavy lifting until the books arrive and the Nine Sacred Keys to Wealth idea gets a chance to breathe.
