Big Bam-Book Slot RTP, Details & Wager Limits

The Big Bam-Book slot game takes place across 3 rows and 5 reels. Unlike online megaways slots, which offer thousands of ways to win, this one sticks to a more traditional 10-payline setup. Therefore, a winning combination in the base game is formed when matching symbols align on any of these, starting from the leftmost reel. It’s slightly different in free spins—you can score wins even when the symbols aren’t lined up next to each other.

When it comes to placing your bets, slot sites let you start with a minimum of 10p or go all out with a maximum stake of £100. Adjusting your stake is straightforward—hit the coins icon to dive into the bet configuration menu, where you’ve got 25 options to choose from. Plus, if you’re playing at a non-UK Big Bam-Book online casino and are in for the long haul, the autoplay feature lets you sit back and relax with 10, 20, 50, 100, 250, 500, or even 1,000 automatic spins. Feel free to also turbocharge the spins by clicking the lightning icon.

The theoretical Big Bam-Book RTP in regular play stands at 96.31%, narrowly higher than the online slot games average. Push Gaming also presents a slightly lower variant, 94.42%. And for the volatility? It’s high, so expect some wild swings.

The Big Bam-Book max win is a solid 10,000x your stake! It’s not quite as massive as what you’ll find in other Push Gaming slots like Razor Shark, but it’s still nothing to scoff at. I found that focusing on triggering the free spins feature is key to hitting this. That’s where the big wins can really stack up, especially with those non-adjacent symbol wins.

Theme – A Tranquil Mountain Village Unfolds an Epic Quest

The Big Bam-Book slot game is nestled in a serene mountain village, with a clear and uncluttered interface that draws you right into the peaceful setting. The visuals are sharp, vibrant, and perfectly balanced—no overwhelming elements, just a crisp, clean layout for a clear view of the symbols and what’s happening on the reels.

Since the setting is a quiet village, the background music is as minimal as it can get, with just a few subtle sounds like birds chirping, leaves rustling, and a flowing river. However, a couple of sound effects help complement this tranquillity, like the sound of the reels spinning and an underlying beat that ramps up the tension, especially when you’re close to triggering a feature.

The lowest-paying symbols in the Big Bam-Book slot are the classic diamonds, spades, hearts, and clubs, but each comes with its own unique twist to fit the theme. Then we’ve got the higher value symbols—think martial arts weapons and fierce characters. There’s also a wild symbol that can substitute for others, along with special symbols like the mystery bamboo, which you might recognize from another Push Gaming favourite, Big Bamboo. Here’s the lowdown on the symbols and what they’re worth:

Symbol	Payouts/Info
Diamond	3, 4 or 5 = 0.1, 1 or 5 x stake
Spade	3, 4 or 5 = 0.1, 1 or 5 x stake
Club	3, 4 or 5 = 0.2, 2 or 10 x stake
Heart	3, 4 or 5 = 0.2, 2 or 10 x stake

Nunchaku	3, 4 or 5 = 0.5, 5 or 25 x stake
Raccoon	3, 4 or 5 = 2, 20 or 100 x stake
Monkey	3, 4 or 5 = 5, 50 or 200 x stake
Panda	2, 3, 4 or 5 = 1, 10, 100 or 500 x stake

Golden Bamboo	Reveals Instant Prize symbols and Scatters
Instant Prize	Bet multipliers; Values range from 1 to 100 x stake

Big Bam-Book Mobile

Push Gaming absolutely nailed the Big Bam-Book mobile slot. It runs perfectly well when playing at mobile casinos using your iOS, Android, or Windows devices, all thanks to the smooth performance of HTML5. In portrait mode, menu options are neatly tucked away at the bottom, giving everything a cleaner look. Even more so, when I flipped my device to landscape, the reels took centre stage and appeared much bigger, though, as expected, most of the background disappeared. Also, the menus popped back to the right, just like on the desktop.

Big Bam-Book Bonus Features

The Big Bam-Book slot game is a real standout largely due to its 5 compelling bonus features. These include the Mystery Bamboo Symbol, Golden Mystery Bamboo Symbols, Free Spins, Bonus Buy, and Push Bet. Let’s dive into each of these and see what makes them so exciting.

Mystery Bamboo Symbol

If you land 3 or more Mystery Bamboo symbols during the base game or free spins, you’ll trigger the Mystery Bamboo Expansion. When this happens, the Mystery Bamboo symbols transform into the same symbol type, either a Wild, a regular paying symbol or a Golden Mystery Bamboo, and expand to cover all the reels where they appear.

Any new winning lines formed by these symbols will be paid out, and if a previously awarded payline now includes a Mystery Bamboo Symbol, it will be paid again.

Golden Mystery Bamboo Symbol

The Golden Mystery Bamboo symbol reveals instant prize symbols with bet multipliers of x1, x2, x5, x10, x25, x50, or x100. In the base game, these can also reveal Scatters once per reel.

Free Spins Feature

You activate the free spins feature by landing 3 or more Scatters during the Base Game or the Golden Mystery Bamboo Feature. More specifically, landing 3, 4, or 5 Scatters will award you 8, 12, or 15 free spins, respectively, with the chance to increase multipliers up to x3 during the Golden Mystery Bamboo Feature.

Once in the Free Spins, Scatters can land anywhere on the reels and are collected into a multiplier metre. For every 4 Scatters you collect, you move up a level and get awarded the following:

• Level 1: x2 multiplier and 5 extra spins
• Level 2: x3 multiplier and 5 extra spins
• Level 3: x5 multiplier and 5 extra spins
• Level 4: x10 multiplier and 5 extra spins

Bonus Buy Feature (Not Available in UK Online Casinos)

The Bonus Buy feature lets you purchase the progressive free spins directly. To do this, click on the star button and adjust your base bet amount using the ‘+’ or ‘-‘ buttons and choose one of the options, depending on the number of bonus symbols you want:

• 3 Bonus symbols for 63.6x your base bet with an RTP of 96.32%
• 4 Bonus symbols for 138.2x your base bet with an RTP of 96.37%
• 5 Bonus symbols for 187.6x your base bet with an RTP of 96.3%
• A random option for 100x your base bet with an RTP of 96.36%

Push Bet (Not Available in UK Online Casinos)

The Push Bet lets you increase your bet to boost your chances, as follows:

• Scatters – Adds 20% to your total bet for a better shot at landing Scatters
• Mysteries and Scatters – Raises your bet by 40%

Toggle it on or off with the switch within the bet configuration menu. Winnings are calculated based on your original base bet, not the increased amount.

Big Bam-Book Slot

Big Bam-Book has what it takes to keep you on edge with its blend of features, high volatility, and a 10,000x max win—perfect for when you’re craving something unique. If you prefer steady, low-risk games, this one might feel a bit too intense.

Pros

• Competitive RTP (96.31%)
• Innovative features, including free spins
• High-quality graphics and smooth animations
• Easy-to-navigate controls
• Versatile betting range

Cons

• No progressive jackpot

Big Bam-Book is one of those slots that really grabs you. With a max win of 10,000x, it’s got some serious potential, though it doesn’t really compare with the ever-growing sums found in progressive jackpot slots. The high volatility keeps things edgy—you never know when the big one’s coming. I was looking forward to seeing some unique features from Push Gaming that weren’t just variations of those in Big Bamboo. Still, the Mystery Bamboo and Golden Mystery Bamboo symbols, amongst many more, bring a nice touch to it largely thanks to the instant prizes and multipliers that come with it.

In terms of gameplay, you’ll need to spin the Big Bam-Book demo a few times to really grasp what’s happening, so I wouldn’t say it’s beginner-friendly. All in all, however, while it may not top the list of best online slots for everyone, it still offers a fun challenge that’s definitely worth exploring. My advice? Try the Big Bam-Book free demo slot first—it’s the best way to see if it’s your style before committing.
