What Is King of the Ring?

What Is Book of Jurassic?

King of the Ring drops you ringside at a championship boxing match. From the first spin, you’re immersed in the roar of a crowd, the glare of spotlights, and the energy of a title bout. The graphics are sharp—boxing gloves, championship belts, the champion himself—each symbol reinforces the athletic theme without veering into kitsch.

Book of Jurassic is a book-style adventure slot set in the Jurassic period. You’re an explorer chasing a mystical tome through a lush, dinosaur-filled jungle — a familiar premise, but one Amigo Gaming dresses up with sharp animation and a driving low-frequency soundtrack. The 5×3 grid and 10-payline structure is standard for the genre, and if you’ve played Book of Ra or Book of Dead before, the mechanics will feel immediately familiar.

The 3×3 grid is compact, unusual in a modern landscape dominated by 5×4 and 6×4 games. This simplicity is deliberate. Five fixed paylines mean no confusion; all lines are always active. Medium-high volatility delivers wins less frequently than medium-volatility peers, but payouts scale larger when they land. The 96.63% RTP is solid, slightly above industry average.

This game suits players who are comfortable with long dry runs between payouts. High volatility means the reels can go quiet for stretches, then deliver a chunky hit during the free spins bonus. It’s not a pokie for casual players chasing small, steady wins. If you want frequent top-ups, look elsewhere. But if you’re happy to ride out a lean session in pursuit of an expanding symbol that covers every reel, this is your game.

Betting Range

The minimum bet is $0.10 per spin and the maximum is $100.00, covering a wide range of player budgets. Because the max win is 6,000x your stake, a $0.10 spin gives you a theoretical ceiling of $600, while a $100 spin takes that to $600,000 — though hitting the maximum during a single session is exceptionally rare. Start at $0.10 or $0.20 per spin until you’re comfortable with the rhythm of the game.RTP and Volatility

96.63% RTP

1. Open the paytable first by tapping the three-dot menu on the left side of the reels. Check which symbols pay the most — in this game, the explorer character and the T-Rex top the chart.
Medium-high volatility
2. Set your bet using the stake button at the bottom of the screen. Use the plus and minus controls to adjust. Stick to the lower end of the range until you understand how often the free spins trigger. means:
3. Press the main spin button to play one round at a time, or activate autoplay using the circular arrows button. Turbo mode (the lightning bolt) speeds up each round.
Fewer payline hits than medium-volatility games
4. Wins are paid when three or more matching symbols land left-to-right on one of the 10 fixed paylines, starting from reel one.
Larger payouts when wins arrive
5. The free spins bonus triggers when three or more Book symbols land anywhere on the reels in a single spin. You receive 10 free spins and a randomly chosen expanding symbol.
Extended dry spins punctuated by knockout paydays
6. After any win, there is no gamble feature in this game — your payout is credited automatically to your balance.
Higher risk, higher reward appeal

Try this: Set a session budget of $20 before you open the game, play at $0.10 per spin, and aim for at least one free spins trigger before you decide whether the game is clicking for you.This profile suits bankroll-disciplined players comfortable with volatility swings. Casual, session-limited players might prefer medium-volatility alternatives.

Symbols and PaytableBetting Range and Accessibility

Book of Jurassic carries 10 symbols across two tiers. The low-paying group uses standard playing card faces — 10, J, Q, K, and A — which pay between 0.5x and 15x your bet per line for a five-of-a-kind combination.Minimum stake:

$0.10 per spin

The high-paying group is where the action is. A pterosaur, triceratops, and T-Rex make up the mid-range premiums, while the main explorer character sits at the top of the regular symbol table. Published paytable values show the explorer paying up to 500x your bet per line for five on a payline — though these are dynamic multipliers, meaning the actual dollar amount scales with your chosen stake.Maximum stake:

$100 per spin

The Dinosaur Book symbol does double duty. It acts as both the wild and the scatter. As a wild, it substitutes for all other symbols except the special expanding symbol that appears during free spins. As a scatter, landing three or more anywhere on the reels triggers the bonus round. The Book pays up to 200x your bet per line in its own right for five of a kind.

The betting range is accessible. The $0.10 minimum welcomes budget players; the $100 ceiling serves high-rollers. At max bet, a 1,275x win scales to $127,500, respectable for medium-high-volatility play.

Bonus Features

Note:

Free Spins with Expanding Symbol Blackspins lists a range of $0.50–$50, but multiple independent sources (Casino.info, SlotJudge, SlotCatalog) cite $0.10–$100. We recommend verifying your operator’s exact range before playing, as some casinos may cap limits differently.

Three or more Book scatter symbols anywhere on the reels trigger 10 free spins. Before the round begins, the game randomly selects one standard symbol to become the expanding symbol for the entire free spins session — it could be the explorer, the T-Rex, or any other regular symbol from the paytable.How to Play King of the Ring — Step by Step

When that chosen symbol lands on the reels during free spins, it expands to fill all three positions on its reel. Critically, wins from the expanding symbol are paid regardless of whether the symbols on adjacent reels are contiguous — it pays across all active paylines as long as matching expanded symbols appear. This is where the 6,000x maximum win becomes a realistic possibility, particularly if the expanding symbol is a high-value character like the explorer and it covers multiple reels simultaneously.

Set your stake.

The free spins round does not appear to retrigger from additional Book symbols. Those 10 spins are your window — use them well. Click arrows next to the bet amount to select from $0.10–$100 per spin.

Outside of free spins, the Book symbol substitutes for any other regular symbol to help complete winning combinations across the 10 paylines. It cannot replace the special expanding symbol during the bonus round. Think of it as a standard wild with the added ability to trigger the most important feature in the game.
