How Book Of Power Plays Inside Our Lobby

Book Of Power is a five-reel, ten-payline slot produced by iSoftBet, and we carry it in the mantrigame slot rooms alongside titles like Gates of Olympus and Mahjong Ways. The game's core pull is its Book mechanic: a single Book symbol acts as both wild and scatter, and three or more anywhere on the reels launch a set of feature spins where

one randomly selected symbol expands to fill full reels. Volatility runs high, which means longer stretches between big symbol hits but noticeably larger payouts when the expanding symbol lands across multiple reels. We stream it at the same frame rate as our live casino tables so the reel animations stay sharp whether you are on 4G or Wi-Fi.

HOW WE RUN THIS GAME

Fair Play and Audit Standards Behind Book Of Power

We do not simply list Book Of Power in our lobby — we vet how it is integrated, how its RNG is certified, and how its payout data is reported to us.

iSoftBet Studio Certification

Book Of Power is developed and certified by iSoftBet, whose games pass independent RNG audits before release. We source the title directly from the studio's certified distribution layer, not through unchecked third-party mirrors.

RNG Verification on Every Spin

Each spin outcome in Book Of Power is generated by a cryptographically seeded random number generator that neither we nor the player can influence. The expanding symbol chosen at feature start is determined the same way — random and unmanipulated.

Published RTP Figure

Book Of Power carries a published Return to Player percentage from iSoftBet that we display in the game's information panel. We do not alter this figure — the RTP you see reflects the certified game build running in our lobby.

Session Logging for All Rounds

Every Book Of Power spin — including feature spin sets and retriggered rounds — is logged with a timestamp and round ID on our servers. You can request a session log for any period by contacting support with your account details.

India Region Eligibility Check

Access to Book Of Power depends on local law and is available where local law permits. We surface the game only for accounts where the region check passes at login — ineligible regions see the title greyed out rather than playable.

Account Security During Play

Book Of Power sessions are tied to your authenticated account token, which expires if your session idles. This prevents a second person on the same device from spinning on your balance without re-authenticating through your login credentials.

Book Of Power Here vs Other Platform Experiences

Not every platform that lists Book Of Power delivers it the same way. Here is how what we offer compares across the details that actually matter during a…

Direct Studio Feed
We pull Book Of Power from iSoftBet's certified feed directly — no intermediate aggregator layer that can introduce latency or load the wrong game build. You get the same certified title the studio releases.
India-Optimised Account Flow
Your account, your UPI or Paytm wallet, and the Book Of Power lobby are all connected in one session. Platforms that route Indian accounts through overseas payment rails add unnecessary steps — we keep it local.
Reel Load Speed
Book Of Power's assets load under four seconds on 4G in our lobby. Platforms hosted on overseas servers often add two to three extra seconds of load on Indian mobile networks, which disrupts the session rhythm.
Feature Spin Visibility
We display your expanding symbol selection prominently above the reels at the start of each feature spin set. Some platforms hide this detail in a small corner label, making it hard to track which symbol to watch for.
Round History Access
Your Book Of Power round history — including every feature spin and retrigger — is accessible in your account history tab for up to 90 days. Many platforms provide no more than 30 days or charge for extended access.
Support With Game Knowledge
Our live chat agents understand Book Of Power's mechanics, not just account billing. If you have a question about why a retrigger did not extend your spin count, they can explain the rule rather than escalate every game query.
No Upsell Interruptions
We do not push pop-up promotions into your Book Of Power session. Some platforms interrupt feature spin rounds with modal overlays for other products — we let the game run clean so the feature experience is not broken.
SIX DEFINING FEATURES

Six Elements That Shape Book Of Power at mantrigame

Book Of Power stands out in our slot rooms because of how its individual mechanics stack. These six elements are what India players mention first after their initial feature spin session — each one…

01
Dual-Role Book Symbol One symbol covering both wild substitution and scatter trigger duties simplifies reading the reels — you watch one icon instead of two, and every landing matters whether it substitutes or counts toward the three needed to launch feature spins.
02
Random Expanding Symbol Pick The expanding symbol for each feature spin set is drawn randomly at the moment the round starts, not predetermined by the base spin. This keeps every feature set distinct and prevents any single symbol from becoming a predictable pattern.
03
High Volatility Profile Book Of Power is deliberately high-volatility — longer dry stretches are part of the design, not a flaw. When the expanding symbol does land across multiple reels, the payout reflects that wait. Understanding this makes sessions less frustrating and more strategic.
04
Retrigger Mechanism Three or more Book symbols during an active feature spin set extend the round rather than ending it. The retrigger uses the same expanding symbol, which means a well-placed retrigger can compound the value of an already-active feature round.
05
Sharp Reel Animation The expanding symbol stretch animation is rendered at a frame rate that stays smooth on mid-range Indian Android devices. The visual payoff of watching a symbol fill an entire reel is part of the experience — we do not let frame drops undercut it.
06
Certified RTP Display Book Of Power's RTP figure from iSoftBet is visible in the game panel before you start a session. Checking it takes two taps. We surface this because it helps you decide whether high-volatility play matches what you want from this session.

Your Book Of Power Questions, Answered

These are the questions that come up most often from people who open Book Of Power for the first time or return after a long session gap. We have answered each one specifically for how the game runs in our lobby.

The Book symbol serves as both wild and scatter in the same game. As a wild it substitutes for any other symbol on a payline. As a scatter, landing three or more anywhere on the five reels — regardless of payline position — triggers the feature spin round.

At the moment your three Book scatters land and launch the feature spins, the game's certified RNG randomly selects one symbol from the paytable. That symbol is displayed above the reels and will expand to fill any reel it lands on during the entire feature spin set.

Yes. If three or more Book symbols land during an active feature spin set, the round extends with additional spins. The same expanding symbol stays active through the retrigger — it does not reset to a new random pick when the retrigger fires.

High volatility means individual base-game spins pay out less frequently than in a low-volatility slot. The design places value on the feature spin sets rather than on regular payline hits. Sessions can run for stretches with small returns before a feature round changes the total significantly.

Tap the information icon inside the Book Of Power game window — usually a small 'i' in the corner — and the certified RTP figure from iSoftBet appears in the game details panel. We do not alter this number from the studio's published specification.

Yes, Book Of Power loads in your mobile browser through your account — no separate app download is needed. The reel grid scales to portrait and landscape on Android and iOS, and the spin controls are touch-mapped so the button sits where your thumb naturally lands.

Note the round reference number visible in your session history and contact our live chat or email support team with that number. We retrieve the server-side round log, verify the outcome against the certified RNG record, and report back what the round should have paid.
