Review Methodology – How We Tested

On March 22, 2026, I used my MacBook (Chrome) and my iPhone 17 Pro Max (Safari)’s 5G networks to review The Slotfather Book of Wins.

I started at 11:28 AM EST with $2,231.79 and stopped at 11:33 AM EST with $2,224.65.

I lost $7.14 by betting $0.20 (SuperSlots‘ minimum bet) per spin, spinning the reels 100 times.

I recorded my MacBook session.🎰

From spins 11-20, I scored 5 wins, but on the 14th spin, I triggered the hold-and-win feature and won $1.10.

From spins 21-30, I scored 4 wins.

From spins 31-40, I scored 2 wins.

From spins 41-50, I hit a dry spell and got no wins.

From spins 51-60, I scored 2 wins.

From spins 61-70, I scored 1 win on the 61st spin, triggered the hold and win feature, and won $3.66.

From spins 71-80, I scored 1 win.

From spins 81-90, I scored 2 wins.

In the last 10 spins, I scored 3 wins.💰

Technical Performance and Hardware Testing

I tested the spin, stop, and auto-play buttons.

I tested how long it took for the game to launch, and found that on my MacBook it took 3 seconds, whereas using my iPhone it took 5 seconds.

I noticed that after my session, my MacBook was slightly warm, whereas my iPhone stayed cool.

I looked and saw that I used about 1-2% of my MacBook’s battery, whereas on my iPhone, I used less than 1%.🛡️

Mobile User Experience

I tested the game on my iPhone and found that, when held vertically, it filled the entire screen.

The gameplay was smooth and uninterrupted.

However, holding the phone horizontally was not the greatest experience.

The game didn’t fill the screen, leaving the browser tabs I was looking at visible.

⚠️ Friction Points Identified

  • 11:29 AM: Slower load time (5s) observed on iPhone compared to MacBook.
  • 11:31 AM: Significant 10-spin dry spell (Spins 41-50) highlighting volatility.
  • 11:32 AM: Sub-optimal landscape UI on iPhone Safari showing browser tabs.

Game Comparison Analysis

Game Verdict
Slotfather 1 & 2 “Book of Wins” blows both away with hybrid mechanics.
Dr. Jekyll & Mr. Hyde Both are great, fresh games with the latest features.

Comparison and Feature Analysis

Compared to the original Slotfather and the Slotfather 2, it blows both of these games away.

It combines the mechanics of a book of mechanics with a hold-and-win feature.

It’s not even close.

Compared to Dr. Jekyll & Mr. Hyde, I thought both games were great.

They are both new and fresh games with the latest features.

I do wish it had cascading reels like Super Sugar Pop and a double-up feature like Safari Sam.

It would have been nice if it had a countdown feature like Take The Bank had.

Pro Tip

Set your loss limits before you start playing, because this game has medium-high volatility.🛡️

Pros

  • Innovative hybrid mechanics.
  • Smooth vertical mobile play.

Cons

  • Landscape mobile UI needs work.
  • No cascading reels.
