Book of Sun Multichance Review
Most book slots give you one expanding symbol and stop there. This Book of Sun slot, released by 3 Oaks (formerly Booongo) in May 2019, keeps adding them. Three Books open 12 free spins with one expanding symbol of your choice, and every retrigger brings another, until as many as nine symbols can stretch across the reels at once. The Book doubles as Wild and Scatter, the grid is a classic 5×3 with 10 lines, and stakes in the official demo run from £0.20 to £26 per spin. Our Book of Sun slot review walks through the paytable, the bonus and where to play Book of Sun in the UK.
Trusted Casinos with Access to Book of Sun Multichance
Any operator with a 3 Oaks Gaming catalogue can host the game, and the ones listed here are our starting shortlist. A good Book of Sun casino should hold a UK licence, take GBP and show the stake range in the game info panel, since limits shift from one site to the next.
One Book, Two Jobs and a Growing Bonus
Book of Sun Multichance takes the familiar Egyptian slot theme and adds a more feature-driven bonus system. The 5×3 reel layout and 10 fixed paylines keep the base game easy to understand, while the golden Book symbol provides two important functions. It acts as a Wild during regular play and also works as a Scatter that can trigger the Free Spins feature. The main attraction is the expanding-symbol mechanic, which becomes progressively more powerful when the bonus round is retriggered. Other book-style and Egyptian releases are ranked side by side at Sun Slots UK.
RTP and Volatility
Book of Sun Multichance is generally listed with an RTP of 95.4% and high volatility. This combination means that winning sessions can be uneven, with longer periods between significant payouts and a greater emphasis on the bonus feature. RTP is a theoretical long-term percentage rather than a guarantee of what you will receive during an individual session, and the exact game configuration may differ between casino versions. At an operator such as Vegas Wild Casino, the game info panel shows which RTP setting is live.

How the Book of Sun Multichance Bonus Works
Three Books anywhere on the reels start 12 free spins, and before the first one you pick which regular symbol will expand. The Book itself is off the list. Whenever your chosen symbol lands, it stretches to fill its reel and pays regardless of payline positions. Catch three more Books during the round and you get another 12 spins plus a second expanding symbol, a cycle that can repeat until nine symbols are active together. A single expanding symbol on a wider line set is covered in our Sun of Ra review.
- Book as Wild and Scatter. It fills in for regular symbols and pays up to 200x the total bet on its own.
- Your pick. Before the round starts you choose the first expanding symbol yourself.
- Twelve to begin. Three Books award 12 free spins.
- Stacking retriggers. Each new set of three Books adds 12 spins and one more expanding symbol.
- Nine at most. The feature tops out once all nine regular symbols expand. Long rounds like this are a good moment to check the tools listed on our Responsible Gaming page.
- Line-free payouts. Expanded symbols pay independently of payline shapes. How we vet the casinos that host the game is set out on our License & Legality page.
Book of Sun Multichance Symbols and Payouts
Five pharaohs on a line pay 5,000x the line bet, the richest result in the game. Horus follows at 2,000x, then the scarab and the bird at 750x each. These four premiums also pay for just two of a kind. The card royals need three to pay, with A and K reaching 150x and Q, J and 10 stopping at 100x. All values below are multiples of the line bet. If your casino shows different values, report it through our Complaint & Proposals form.
Book of Sun Multichance on Mobile
A 5×3 grid with 10 lines is about as phone-friendly as slots get, and the HTML5 build loads straight in Safari or Chrome. The symbol-choice screen at the start of free spins is large enough to tap comfortably, so nothing feels cramped on a small display. After your Book of Sun login at the casino, the game runs from the same account and balance you use on desktop. Our Sun Vegas Casino review covers a mobile lobby where browser slots like this one run without an app.
