Book of Dino Deluxe: Explore the Lost Dino World and Hunt Down 4,000x Rewards

Book of Dino Deluxe by Swintt is their latest addition to the Book of Dino series. Previously, they had my attention with Book of Dino Unlimited, where the 5,000x max win kept things interesting. This time, the ceiling drops to 4,000x, but with respins added into the bonus round, I wanted to see how this prehistoric run would actually play out.

This is a five-reel, three-row slot with 5 paylines, keeping that classic book-style format intact. The reels are packed with dinosaurs like Pterosaurs, Tyrannosaurus, and Coahuilaceratops, all set on a volcanic plateau. The RTP sits at 96.01%, and the volatility is high, something that became very clear during my session.

During my playthrough, I was landing wins roughly every 3 to 4 spins, but the returns stayed between 1x to 2x my bet. That’s expected for a high-volatility game, but what stood out were the dry spells that stretched close to 30 spins, so you need to be ready for that.

That said, the base game still had its moments. I managed a couple of 20x wins, and my highest base game hit reached 32x my bet, which helped keep things from going completely flat.

There’s also a gamble feature available after wins. You can push your luck there, but unless you’re comfortable risking what you’ve already earned, it’s better to stay away from it.

There are two ways to trigger the bonus round here. The first comes from landing three or more bonus symbols, which awards a mystery prize up to 100x your bet. I triggered this after around 50 spins, and it returned 60x my bet, which was a praiseworthy boost.

The second and more important feature comes from landing three or more wild symbols, which also act as scatters. This triggers 10 free spins, and during the feature, you get respins along with the expanding special symbol mechanic. This was the better part of my session, as I walked away with 121x my bet from that round.

If the base game isn’t working in your favor, there’s a bonus buy option costing 100x your bet, along with an ante bet at 1.5x that increases your chances of triggering the bonus. I didn’t go for either, as my session was already doing enough.

Overall, Book of Dino Deluxe follows the familiar book-style setup with a few added touches like respins. The bonus round does the heavy lifting, while the base game can feel stretched at times.
