Book of Dead Game Mechanics
Book of Dead is a five-reel, nine-payline slot with a return-to-player (RTP) percentage displayed before you play. The game features a wild symbol (the Book itself) that expands to fill entire reels during the base game and free-spin rounds. When the Book lands on reels 1 and 5 simultaneously, it triggers 10 free spins with an expanding symbol that remains locked throughout the bonus round.
On icb138, you select your bet size before each spin—the platform displays the minimum and maximum bet for your account tier. Payouts are calculated instantly after each spin, and your balance updates in real time. The game runs on RNG (random number generator) mechanics, meaning each spin is independent and fair.
Book of Dead is available on desktop and mobile at icb138. The interface adapts to your screen size, so you can play from a computer in Jakarta or on your phone during a break in Surabaya. The game loads quickly and runs smoothly on standard internet connections.
Welcome Offer and First Deposit
When you open a new account at icb138, you're eligible for our welcome offer. The offer applies to all games, including Book of Dead. Here's how it works: you complete your first deposit, and icb138 credits an attractive bonus to your account. The bonus is subject to a play-through requirement—you must wager the bonus amount a set number of times before you can withdraw it.
For example, if your bonus is credited and the play-through is 8x, you need to place wagers totaling 8 times that bonus amount across any game (Book of Dead, live blackjack, Domino QQ, etc.). Once you reach the threshold, the bonus converts to real money in your main balance and is fully withdrawable.
To claim the welcome offer, log into your account after your first deposit clears. The bonus should appear automatically in your account dashboard. If it doesn't, contact our support team—they'll verify your deposit and credit the bonus manually. The offer expires after a set period (typically 30 days), so claim it soon after you join.
Your welcome bonus at icb138 is designed to give you a chance to explore Book of Dead and other games without risking your full deposit immediately.
Weekly Cashback on Book of Dead Spins
Beyond the welcome offer, icb138 runs a weekly cashback program that applies to all games, including Book of Dead. Every week, we calculate your total wagers across all titles and return a percentage of your losses as cashback. This cashback is credited to your account every Monday morning and is immediately withdrawable (no play-through required).
The cashback percentage depends on your tier. New members start at a base tier and earn higher cashback rates as they accumulate play. For instance, a member who plays regularly might move from non-specific info weekly cashback to non-specific info or higher. Your tier resets monthly, so consistent play throughout the month keeps you at a higher tier for the following week.
Book of Dead spins count fully toward your weekly cashback calculation. If you spin Book of Dead and lose, that loss contributes to your cashback tier. If you win, the win reduces your net loss for the week, which may lower your cashback amount—but you still keep your winnings.
Tracking your cashback
Your account dashboard shows your current tier, this week's wager total, and your pending cashback amount. You can see exactly how much cashback you've earned and when it will be credited.
Cashback is calculated on net losses—meaning total wagers minus total winnings. If you have a winning week on Book of Dead, you won't earn cashback that week, but your tier remains active for the following week.
Referral Program and Tournament Offers
icb138 rewards members who invite friends to the platform. When you refer someone and they complete their first deposit, both you and your referred friend receive a referral bonus. The bonus amount depends on the deposit size and is credited within a few hours of their deposit clearing.
There's no limit to how many friends you can refer, so if you enjoy Book of Dead and know others who do, you can build referral earnings over time. Each referral also counts toward your monthly activity tier, so active referrers often reach higher tiers and unlock better cashback rates.
Beyond referrals, icb138 runs seasonal tournaments tied to major events. During Liga 1 season, Piala AFF tournaments, and holidays like Idul Fitri and Idul Adha, we launch slot tournaments where players compete for leaderboard positions. The top performers earn tournament prizes—bonus credits, cashback boosts, or free spins on Book of Dead and other titles. Tournament eligibility and prize structures are announced in your account dashboard.
