Bookie of Odds Slot Review

Playing Bookie of Odds - First Impressions

I loaded up Bookie of Odds expecting a standard Book of Ra clone and got something a bit more interesting. Developed by Triple Edge Studios for Microgaming and released in March 2019, this is essentially a horse racing reskin of Book of Oz -- same maths model, same mechanics, same payouts. But the theme captures that buzzy atmosphere of big British racing days like Royal Ascot and the Grand National, which honestly suits the format well.

It runs on a 5x3 grid with 10 paylines. The artwork is decent if not spectacular, leaning into a classic racecourse vibe with betting slips, jockeys and the Bookie character himself. High volatility throughout, so expect dry patches between meaningful hits. I found the base game fairly quiet, but the tension builds nicely thanks to the Respin mechanic sitting just below the reels.

Bookie of Odds Symbols and Paytable

The top-paying symbol is the Bookie character, awarding 500x your total bet for five of a kind. The Gold Book acts as both Wild and Scatter, paying 200x for a full line of five. One detail worth noting: high-value symbols only need two on a payline to form a win, while low symbols and the Book Wild require a minimum of three. That distinction matters more than you would think during longer sessions -- it keeps small wins trickling in from the premium icons even when the reels are not cooperating.

How Bookie of Odds Free Spins Work

Landing three or more Gold Book Scatters anywhere triggers the Free Spins Bonus. Three Books give you 10 free spins plus 2x your bet, four Books award 12 spins plus 20x, and five Books hand you 25 spins plus a tidy 200x payout. Before the round starts, a symbol is randomly selected to become the expanding symbol for the duration.

When that chosen symbol lands during free spins, it expands to fill the entire reel and pays in any position on a line. Retriggers are possible if three or more Books appear mid-bonus. The maximum win potential in this feature is 5000x total bet. During my testing I triggered the bonus after a fairly stubborn drought, and the expanding symbol mechanic delivered the most memorable moments -- though the selected symbol makes or breaks the round.

Bookie of Odds Respin Feature - Is It Worth the Cost?

After every base game spin, a RESPIN button appears below each reel with a price tag attached. You can respin any individual reel as many times as you like, paying the displayed cost each time. The price changes dynamically depending on what is already showing on the other reels.

This is where it gets tactical. I tested it by landing two Books on reels 3 and 4, then respinning the remaining reels to chase the bonus trigger. It took 10 respins at a combined cost of around 65 coins before I finally got the third Book. The free spins round returned roughly 70 coins plus about 14 from the respin cycle itself, leaving a modest net profit. It does not always work out that neatly, but it adds a genuine layer of player agency you rarely see in slots.

The RTP shifts slightly when you use respins -- Microgaming lists it at 96.31% in standard mode and 96.50% in respins mode. That small bump suggests the feature is mathematically fair, though chasing near-wins can drain your balance quickly if luck is not on your side.

Bookie of Odds RTP, Volatility and Max Win

This is a high volatility slot with a betting range of 0.10 to 25.00 per spin. The top payout caps at 5000x your total bet, which translates to 125,000 at maximum stake. RTP sits at 96.31% in normal play and edges up to 96.50% when using the Respin feature. For UK players comfortable with volatile games, those numbers are perfectly solid.

Final Verdict on Bookie of Odds

Is Bookie of Odds original? Not really -- it shares its DNA with Book of Oz and ultimately traces back to the Book of Ra template. But the horse racing theme gives it a distinctly British flavour, and the paid Respin feature genuinely adds something. The expanding symbol free spins remain as compelling as ever, and the sense of control from choosing when and where to respin is unusual for a slot. If you enjoy high volatility Book-style games and fancy a punt on the horses, this one delivers a solid session.
