4 Bonuses Bonanza Review 2026

Q: Where does Plinko even come from?

The pegboard drop was popularised by the U.S. game show The Price Is Right, which introduced its "Plinko" pricing game in 1983. The physical idea is older still — a bean machine (Galton board) demonstrating the binomial distribution — but casino versions like this one copy the game-show board almost exactly, then swap the cash slots for multipliers and, in SmartSoft's case, layer in named bonus rounds on top.

Fact Sheet: 4 Bonuses Bonanza

Game Name	4 Bonuses Bonanza - Plinko Spin
Provider	SmartSoft Gaming
Release Date	November 22, 2024
RTP	98.06%
Volatility	Medium–High (per third-party trackers; not officially published by SmartSoft)
Max. Multiplier	x2000
Bet Range	$0.10 – $100 (may vary by casino)
Key Features	4 named bonus rounds (Joker X, Book of Joker, Joker Train, Sweet Joker) · 98.06% RTP · Bonus Buy · RNG certified by iTech Labs
PlinkoNet Rating	4.8/5

Payouts & the x2000 max

The payout structure is twofold. The base game offers a range of lower multipliers for consistent, small returns, while the true potential is unlocked inside the bonus rounds — where you can hit the game's maximum multiplier of x2000. With a max bet of $100, that's a potential top win of $200,000. The headline 98.06% RTP is a blended figure — the four bonus rounds carry their own individual RTPs, from 97.73% (Joker Train) up to 98.11% (Joker X).

SmartSoft doesn't publish an official volatility rating for this title. Independent game trackers place it Medium-to-High; the base game's own multiplier slots pay small and often, while chasing the bonus rounds or using the Bonus Buy pushes real risk — and reward — noticeably higher.

What is 4 Bonuses Bonanza - Plinko Spin by SmartSoft Gaming?

At its core, 4 Bonuses Bonanza - Plinko Spin is a fresh take on the beloved Plinko concept. Instead of just watching a disc fall into a multiplier slot, the game builds a layer of anticipation around its four special bonus games. This is a signature move by SmartSoft Gaming, a provider known for creating visually appealing and mechanically inventive casino games that challenge the status quo.

Our first impression is that this game is designed for the modern player who seeks more than repetitive gameplay. It promises not just a game of chance, but a game with chapters and climaxes — the "Bonanza" in the title is the central pillar of the experience, making each drop of the disc a potential key to a much larger, more interactive event. Players who prefer a leaner take can compare it with the same studio's PlinkoX.

The four named bonus rounds all run under the game's carnival-joker theme: Joker X (random "Joker Bomb" explosions add to your win), Book of Joker (a randomly chosen symbol expands for bigger combinations), Joker Train (wild-carrying symbols roll through the board) and Sweet Joker (random wilds and bombs stack up during the round). Each has been independently listed with its own RTP between 97.73% and 98.11% — worth knowing since it means your realistic return depends partly on which bonus you land, not just the 98.06% headline.

Visuals, sound & interface

SmartSoft Gaming delivers a polished, vibrant presentation. The visual style is clean and modern, with a high-contrast palette that keeps the board easy to read, and fluid animations — especially the satisfying cascade of the disc through the pegs. The real treat comes alive during the bonus rounds, each with a unique theme and effects that clearly signal a shift from the base game.

The sound design matches the action: a subtle ambient track during normal play, the crisp classic "plink, plink, plink" of the disc, and a more energetic soundtrack when a bonus triggers. The interface is highly intuitive, with bet adjustment, the spin button and the Bonus Buy feature all clearly laid out and fully optimised for both desktop and mobile.

RTP vs house edge

98.06% RTP — returned to players

1.94% house edge

A 98.06% RTP means a house edge of just 1.94% — exceptionally high and among the best value in the category. Over a vast number of plays, the game is programmed to return 98.06% of all wagered money to players.

RNG-certified, not provably fair

SmartSoft Gaming's random number generator is certified by iTech Labs and cross-checked by the Malta Gaming Authority under the studio's MGA/B2B/925/2021 licence. That's a legitimate fairness guarantee — but it's not the same as a provably-fair, seed-verifiable system like some crypto-native Plinko games use. We found no player-facing verification tool for this title, so don't expect one in the lobby.

How a Plinko RTP is actually built — and why we can't show 4 Bonuses Bonanza's table

Every Plinko-style RTP comes from one formula: EV = Σ [P(slot) × multiplier], then RTP = EV × 100%. On a fixed-board binomial Plinko (like BGaming's), that probability is a clean C(rows,slot)/2^rows term, so any reviewer can rebuild the RTP from the paytable alone. 4 Bonuses Bonanza doesn't work that way: the base game pays 0.1×–100× across an undisclosed slot layout, and the real value sits inside four separately-weighted bonus rounds, each with its own quoted RTP (97.73%–98.11%) that SmartSoft blends into the 98.06% headline. Neither the base-game slot distribution nor the bonus-round trigger frequency is published, so we can't reconstruct a per-slot table the way we can for a classic pegboard — we report the studio's own 98.06% figure rather than fabricate one.

Illustrative version of the same maths on a simple 16-row board, just to show the mechanics: (1/65,536 × 1000) + (16/65,536 × 130) + … ≈ 0.9898 → 98.98% RTP. That's the shape of the calculation SmartSoft ran to reach 98.06% for this game — we just don't have their internal slot weights to reproduce it line by line.

How to play — step by step

Set your bet

Begin by selecting your stake, which can range from $1 to $100 per drop.

Launch the disc

Press "Play" to release a disc from the top of the pyramid. As it descends it ricochets off a field of pins, altering its path.

Base game payouts

If the disc lands in a standard multiplier slot at the bottom, your bet is multiplied by that value.

Trigger the bonuses

Land a disc in a special "Bonus" pocket to activate one of four named bonus rounds — Joker X, Book of Joker, Joker Train or Sweet Joker — each with its own mechanic and a slightly different RTP.

Use Bonus Buy (optional)

For a calculated price based on your stake, jump straight into a bonus round instead of waiting for a natural trigger.

Autoplay

Set a predetermined number of drops at a consistent bet level — ideal for players employing specific betting techniques.

Expert tactic — the bonus hunt

Flat-bet a consistent, low-to-moderate stake — the high RTP rewards patience.
Dedicate the session to triggering bonuses; start small to learn their frequency.
Use Bonus Buy sparingly, after wins — never to chase losses.

Key takeaways

98.06% RTP is among the best in the category.
Flat betting extends playtime and maximises bonus chances.
Effective bankroll management is non-negotiable.

Strengths

Highly engaging gameplay — four distinct bonus rounds prevent monotony.
Exceptional 98.06% RTP — among the best return rates in the industry.
High win potential — an x2000 max multiplier enables substantial payouts.
Bonus Buy feature — instant access to the most exciting part of the game.

Weaknesses

Complex for beginners — the array of features can overwhelm Plinko newcomers.
Bonus Buy risk — a double-edged sword that can burn funds if used irresponsibly.
No official volatility rating — SmartSoft doesn't publish one for this title; our Medium–High tag is a third-party estimate, not a certified figure.
Not provably fair — the game relies on iTech Labs RNG certification rather than a player-checkable seed system, so you can't audit individual rounds yourself.

4 Bonuses Bonanza vs the competition

How does it stack up against giants like Spribe Plinko or BGaming's Plinko? The primary distinction is its focus on features over simplicity. Where Spribe's version is a minimalist masterpiece built around straightforward, customizable risk levels, 4 Bonuses Bonanza opts for a video-slot-like experience driven by event-based bonus rounds — less a direct competitor and more an evolution for players who find traditional Plinko too passive. Note this is a distinct title from SmartSoft's own PlinkoX, which sits in the benchmark table below.

	4 Bonuses Bonanza	Spribe Plinko
Style	Feature-rich, bonus-driven	Minimalist
Bonus rounds	4 unique rounds	None
Bonus Buy	Yes	No
RTP	98.06%	lower
Max multiplier	x2000	—

The five Plinko engines that set the benchmark

Whatever version sits in a given lobby, these five studios define the reference points: BGaming, Spribe, SmartSoft, Stake and Hacksaw each make a different trade-off — some chase a bigger max win, some fix the RTP so no operator can quietly lower it, and only some are provably fair rather than simply RNG-certified. 4 Bonuses Bonanza isn't one of these five itself — it's SmartSoft's feature-driven cousin of PlinkoX — but here's the honest five-way side-by-side, pulled from our own review of each game.

	BGaming Plinko	Spribe Plinko	SmartSoft PlinkoX	Stake Original	Hacksaw Dare2Win
RTP	up to 99% (98.98% actual, High/16)	97% (fixed)	~98.5%*	99% (fixed)	88.20%–98.98%
Rows	8–16 (adjustable)	12 / 14 / 16	Fixed board	8–16 (adjustable)	8–16 (adjustable)
Risk levels	3 (Low/Normal/High)	3 (Green/Yellow/Red)	None — fixed	3 (Low/Medium/High)	3 (Low/Medium/High)
Max multiplier	x1,000	x555	x10,000†	~x1,000	x3,843.3
RTP — fixed or configurable?	Configurable — casino sets it	Fixed everywhere	Fixed (per SmartSoft)	Fixed — Stake-exclusive	Configurable — 7 tiers
Provably fair	Yes	Yes (SHA-256)	No — RNG-certified only	Yes	No — RNG-certified only
Full review	BGaming review →	Spribe review →	PlinkoX review →	Stake review →	Dare2Win review →

*SmartSoft doesn't publish an official RTP for PlinkoX; 98.5% is the figure reported by third-party game databases, not a studio-confirmed number — 4 Bonuses Bonanza, this page's title, is a separate game with its own confirmed 98.06% RTP. †PlinkoX's x10,000 needs a 10× Bonus Ball multiplier to land on top of the base 1,000× slot — its base-only ceiling is x1,000, the same tier as BGaming and Stake.

Answers

4 Bonuses Bonanza FAQ

What is the main feature of 4 Bonuses Bonanza - Plinko Spin?

Its four unique bonus rounds — special mini-games triggered by landing the disc in specific pockets, offering a different experience and much higher payout potential than the base game. They transform the game from a simple payout pyramid into an interactive adventure.

Is the 98.06% RTP in this game guaranteed?

The 98.06% RTP is a theoretical, long-term average calculated over millions of spins. It is not a guarantee for a single session, but it indicates the game's overall fairness and high payout programming. Learn more on our Plinko odds and probability page.

Can I play 4 Bonuses Bonanza on my mobile phone?

Yes. SmartSoft Gaming builds its games in HTML5, making them fully compatible with modern iOS and Android devices. The interface is optimised for touchscreens, with no need to download any special Plinko mobile app.

How is this different from PlinkoX by the same provider?

Both come from SmartSoft but target different tastes. PlinkoX is a more streamlined experience focused on classic Plinko mechanics with added multipliers and a cleaner interface, whereas 4 Bonuses Bonanza is built around the thrill of triggering its four distinct, more complex bonus rounds.

Should I use Bonus Buy or wait for the bonus to trigger naturally?

It depends on your risk tolerance. Waiting for a natural trigger is the lower-risk approach that aligns with careful bankroll management. Bonus Buy offers instant excitement but at a high cost and with no guaranteed profit — we advise new players to trigger bonuses naturally first.

Is 4 Bonuses Bonanza RNG-certified or provably fair?

It's RNG-certified, not provably fair. SmartSoft Gaming's random number generator is certified by iTech Labs and cross-checked by the Malta Gaming Authority under SmartSoft's MGA/B2B/925/2021 licence. We found no player-facing provably-fair verification tool for this title, unlike some crypto-native Plinko games — so trust the certification, not a seed-checking feature that doesn't exist here.

How rare is the x2000 top multiplier?

SmartSoft hasn't published slot-by-slot odds for this title, unlike a fixed-board Plinko where every slot's binomial probability can be calculated exactly. What we do know: the x2000 ceiling lives inside the four bonus rounds, not the base game's 0.1×–100× multiplier field, and each bonus round carries its own RTP (97.73%–98.11%) folded into the 98.06% blended headline — so it's inherently rarer than a base-game payout. Treat any specific hit-frequency figure you see elsewhere as unverified until SmartSoft publishes one.

Is there a strategy that changes the odds in 4 Bonuses Bonanza?

Not the underlying odds — every drop and every bonus trigger comes from SmartSoft's iTech Labs-certified RNG, independent of what happened before. What you can control is variance: flat-betting a modest, consistent stake extends playtime and bonus-hunting chances, while repeated Bonus Buy purchases raise short-term risk without improving your long-run return. See our expert tactic above.

Where does Plinko even come from?

The pegboard drop was popularised by the U.S. game show The Price Is Right, which introduced its "Plinko" pricing game in 1983. The physical idea is older still — a bean machine (Galton board) demonstrating the binomial distribution — but casino versions like this one copy the game-show board almost exactly, then swap the cash slots for multipliers and, in SmartSoft's case, layer in named bonus rounds on top.
