Play Book of Inti Slot Game

Ancient Egypt might dominate the "book of" slot genre, but Golden Rock Studios is switching things up with Book of Inti, taking the format to the sun-worshipping civilization of the Inca. Named after the Incan sun god, this slot doesn’t just bring a new backdrop - it also comes with a few twists to the familiar format.

Visually, the game leans into its theme with a bright, golden-hued setting featuring a cascading water temple, stone statues, and ornate carvings. The reels are packed with gold artefacts, including necklaces, statues, and coins, while the highest-paying symbol is a determined-looking conquistador. The setup itself is familiar — Book of Inti is played on a 5-reel, 3-row grid with 10 paylines. The minimum bet starts at 0.10, making it accessible to just about every tier of player.

Golden Rock Studios has been steadily building a portfolio of innovative slots, with titles like Star Gods and Gold N Rocks bringing fresh gameplay mechanics to the table. Book of Inti keeps the core elements of the "book of" formula intact while adding extra strategy through its bonus wheel, which could enhance the free spins round.

Here’s how you can get started and play Book of Inti for yourself:

1. Sign in to your account at Heart Bingo.
2. Head to the online slots page.
3. Search for “Book of Inti” and click the game when it appears.
4. Once it's loaded, click on the pile of coins to find an appropriate stake size.
5. Click the Spin button to get the reels moving.

If you aren't already registered, click on the green 'Sign Up' button in the top right corner and fill in the required fields. You can then verify your account and make a deposit if you want to play Book of Inti with real funds.

The reels feature a mix of traditional high-value symbols and lower-value card royals. The premium symbols pay for two or more on a payline, while lower-value symbols require at least three. A complete paytable is given below:

As in many "book of" slots, the book symbol is both the scatter and the wild. In the base game, it substitutes for any regular pay symbol to complete a winning line. However, in the Free Spins round, it cannot substitute for the expanding symbols once they are chosen.

Free Spins and the Bonus Wheel

Landing 3, 4, or 5 book symbols on the reels doesn't just trigger free spins — it also comes with an immediate payout of 2x, 20x, or 200x the total bet. Players start with eight free spins, but before the round begins, a three-tiered prize wheel spins to determine additional benefits.

• Outer Ring: Randomly selects a special expanding symbol.
• Middle Ring: Awards 2 to 15 extra free spins.
• Inner Ring: Removes one low-paying symbol from the reels, making it easier to land higher-value wins.

The expanding symbol works as expected — when enough land, they expand to cover their reels and potentially pay on all paylines, regardless of positioning. If additional books land during free spins, players could get another spin of the bonus wheel, potentially adding more expanding symbols or removing additional low-paying ones.

Book of Inti brings an Incan twist to the ever-popular "Book of" genre, standing alongside classics like Book of Ra Deluxe and Book of Dead. Players who enjoy these mechanics might also like John Hunter and the Book of Tut or Book of Aztec, which feature similar gameplay just with different themes. All the titles are available in the online slot section at Heart Bingo.
