Book of Sun: Choice Slot Features
I've spent quite a bit of time with Book of Sun: Choice. It keeps the familiar 5 reels, 3 rows and 10 paylines. Egyptian vibe is straight to the point, with neat book animations, but nothing we haven't seen before. The draw is interactivity rather than theme. Base game ticks along with solid line hits, though I'm always waiting for the books. That's where the slot opens up, and where the maths model shows its teeth.
Volatility sits high, and the cap is 5,000x your bet. Stakes are flexible, from £0.20 up to £30 a spin, which suits testing the waters and then upping the ante. The listed RTP is 95.76% in regular play. If I buy the feature, the figure lifts to 97.74%, and the ticket costs 90x bet. That option trims the wait and lines up the part of the game that matters most.

Book of Sun: Choice Slot – Free Spins Feature
Three or more books trigger 12 free spins, and here's the hook I rate most. I pick the Expanding symbol myself. When it lands, it grows to fill reels and pays even when the symbols aren't adjacent on a line. Premiums also pay from two of a kind, so choosing a top symbol can swing sessions. The round keeps the base paytable, but the expansion mechanic changes how lines settle, and that's where chunky screens appear.
Book of Sun: Choice Slot – Additional Free Spins
Retriggers are the sweetener. Land another three or more books and you get 12 extra spins plus an extra Expanding symbol choice stacked on top. I've built sets with several actives, and the board can switch from quiet to lively fast. In full flow you can end up with as many as nine Expanding symbols active, which can blanket a screen and pay across multiple lines at once. That's the route to standout hits here.
Book of Sun: Choice Symbols and Paytable
Book of Sun: Choice uses nine pay symbols, split into five lows and four highs. Lows are Tens through Aces, topping out at 15x for five. Highs are statues, a scarab, and two character symbols. The two premium faces pay from two of a kind, which helps when expansions land thin. The pharaoh sits on top at 500x for five, with the next premium at 200x. The remaining highs come in at 75x for full lines.
The Book symbol is the only special here. It works as both Wild and Scatter, substituting for pay symbols and triggering features. It also carries its own payouts, with 200x for five, 20x for four, and 2x for three in view. During free spins, any chosen Expanding symbol pays on the standard table, but it doesn't need to be adjacent, so lines can settle from scattered positions. That pairing is why the feature carries most of the slot's hit potential.
