SmartSoft Gaming’s Plinko X combines random 1x, 5x and 10x balls with three selectable risk versions and batches of up to 25 separately charged drops. Its official demo Help lists 97% RTP for standard play and a maximum return of 10,000x the base bet on High, reached when a 10x ball lands in a 1,000x pocket. We recommend starting with one ball and B+ switched off in the free demo: B+ adds 50% to the cost of every ball without increasing the stake used to calculate its payout.

What you can control in Plinko X
The ball falls through a pegboard and settles into a multiplier pocket. Two random values determine the return: the ball’s own multiplier and the pocket multiplier. SmartSoft’s Help says outcomes use a random number generator (RNG); tapping faster or holding the drop button does not improve the chance of winning.
The official demo client has a Version selector for Low, Medium and High, an Amount selector for 1, 5, 10 or 25 balls, and a Hold & Drop button. Holding that button continues releasing balls until you let go. Each ball carries its own bet; choosing 25 does not split a single stake into 25 pieces. Auto Play separately lets you set the bet, number of rounds, balls per round and B+ status.
We use the multiplier labels 1x, 5x and 10x to identify balls. That is the information needed to calculate a return, without relying on a particular shade of pink, yellow or orange in the artwork. You cannot select a winning ball type yourself.
| Version | Listed return range | Maximum return on a $1 AUD base bet | How we would use it in a demo |
|---|---|---|---|
| Low | 0.5x–200x | $200 | Start here to learn the controls and distinguish partial returns from profits. |
| Medium | 0.1x–1,000x | $1,000 | Compare its deeper minimum return with Low before increasing the number of balls. |
| High | 0.2x–10,000x | $10,000 | Inspect the 1,000x pocket and bonus-ball calculation. The headline ceiling describes a rare outcome. |
Low’s higher minimum return does not remove losses: a normal 1x ball at 0.5x returns only half its stake. High’s 0.2x minimum is higher than Medium’s 0.1x minimum, but that alone cannot rank their volatility. The frequency of each return also matters. For the underlying terms, use our guide to Plinko rules and multipliers.
The payout calculation: 1x, 5x and 10x balls
Gross return = base bet per ball × ball multiplier × pocket multiplier. SNAI’s published Plinko X rules give this formula and identify 0.2x, 2x, 4x, 10x, 20x, 100x and 1,000x pockets in the board they document. These pocket values should not be substituted for the Low or Medium board: read the payout strip for the selected version.
On a $1 AUD base bet, a 5x ball landing at 0.2x returns $1, which breaks even in standard play. A normal 1x ball in that same pocket returns $0.20, a loss of $0.80. At a 1,000x pocket, a normal ball returns $1,000; a 5x ball returns $5,000; a 10x ball returns $10,000. Subtract the amount charged for the ball to find the profit.
| 1x ball return | 5x ball return | 10x ball return | |
|---|---|---|---|
| 0.2x | $0.20 | $1 | $2 |
| 2x | $2 | $10 | $20 |
| 10x | $10 | $50 | $100 |
| 100x | $100 | $500 | $1,000 |
| 1,000x | $1,000 | $5,000 | $10,000 |
These AUD amounts illustrate the arithmetic; they do not establish an Australian-dollar betting limit or an available AUD account. Maximum-win caps and the currency displayed in the client need their own check.
How rare is the 10,000x result?
The official demo Help describes the High maximum as occurring approximately once every 4,802,650 rounds. It requires both the 10x ball and the 1,000x pocket. That published frequency is not a countdown to a win, and the Help does not give a separate B+ jackpot frequency. We would not apply a generic 16-row edge-pocket probability to this combined outcome: that calculation leaves out the randomly selected ball multiplier.
RTP and B+: what the extra 50% buys
The demo Help publishes six RTP values. Standard Low, Medium and High all return a theoretical 97%. With B+ enabled, the listed values are 97.02% on Low, 97.03% on Medium and 97.01% on High. SNAI’s operator rules also publish 97% for the game. We use these primary-source figures rather than the 98.5% often repeated in other guides.
| Version | Standard RTP | B+ RTP | B+ house edge, calculated as 100% minus RTP |
|---|---|---|---|
| Low | 97% | 97.02% | 2.98% |
| Medium | 97% | 97.03% | 2.97% |
| High | 97% | 97.01% | 2.99% |
B+ increases the chance of drawing higher-value 5x and 10x balls. Its fee is 50% of the base bet per ball, excluded from payout calculations. A $1 base bet therefore costs $1.50 with B+ on. If a 5x ball lands at 0.2x, the return is still $1: the net result is now a $0.50 loss. The bonus-ball frequency changes, so the fee alone is insufficient to recalculate B+ RTP; use the mode’s published figure.
At standard 97% RTP, $100 of total wagers has a theoretical expected loss of $3. This applies to turnover, including money wagered again after a return, rather than to the opening balance. It does not mean a $100 session finishes at $97. Our RTP and volatility guide explains why short sessions can diverge sharply from the average.
A 25-ball batch can cost $37.50
With a $1 AUD base bet, a batch of 25 balls costs $25 in standard mode and $37.50 with B+. Ten such batches commit $250 or $375 respectively before accounting for returns. On an illustrative $50 balance, one B+ batch consumes 75% of that balance in stakes and fees. This is why we prefer one-ball demo drops while checking the controls.
Auto Play offers stop conditions for a single win above a chosen amount, or a balance increase or decrease above a specified amount. Set the number of rounds and balls per round before starting. A stop condition should not be treated as a refund for bets already placed; keep the cost of the whole batch within your chosen session limit. See our bankroll guide for turnover calculations and loss limits.
A useful free-demo check, on desktop or mobile
SmartSoft’s official product page links to its own Play Demo launcher and describes mobile-responsive support. We checked the launcher’s client and English Help. The provider demo opens on a separate page.
- Open the provider’s demo. Use the SmartSoft link in Sources, then select Play Demo. Confirm that the title is Plinko X and the balance is for demo play.
- Select Low, Amount 1 and B+ off. Read the displayed bet currency and limits; do not interpret a euro or demo-credit value as an AUD minimum.
- Release one ball. Compare the amount deducted and the gross return in the history with the payout formula above.
- Switch to Medium, then High, and read each payout strip. Keep the base bet and ball count fixed so that the change you observe comes from the version.
- In demo mode, enable B+ and check that the charge rises to 1.5 times the base bet. Turn it off again before trying a larger batch.
- Open Auto Play and inspect its round count and stop conditions. On a phone, check that you can reach the stop control without covering it with your thumb.
Our site’s free Plinko simulator is a separate educational board. It does not reproduce SmartSoft’s bonus-ball distribution, B+ pricing or six RTP settings. Use the provider’s demo to inspect those features. A short run can confirm how controls work; it cannot establish the true frequency of a multi-million-round maximum result.
Fairness, AUD accounts and Australian access
SmartSoft’s Help identifies RNG-based outcomes. We did not find a seed commitment, revealed server seed or per-round verification workflow in the inspected client and Help. We therefore do not label Plinko X provably fair. The practical difference is that an RNG statement does not give you the inputs needed to recreate an individual drop yourself. Our provably fair verification guide explains that process for games which expose it.
SmartSoft’s product page identifies a Malta Gaming Authority B2B licence, MGA/B2B/925/2021. This describes the supplier’s licensing status; an Australian player still needs to consider the operator and Australian law. ACMA lists online casinos among services providers are prohibited from offering to people in Australia under the Interactive Gambling Act 2001. Accepting AUD, Australian registrations or a local payment method does not establish permission to provide that service.
For readers in Australia, we recommend using the free demo to inspect the game. The Australian legality guide covers the provider restrictions. For a payment claim, check the account currency, game currency, withdrawal terms and verification requirements separately: none follows from the name SmartSoft.
Our verdict and sources
Plinko X offers a useful variation for readers interested in how two multipliers combine: a modest pocket can break even with a bonus ball, while the maximum requires both a high-value ball and a high-value pocket. Low, Medium and High provide explicit controls, and the Help gives separate B+ RTP figures. The drawbacks we would weigh most heavily are the 50% B+ charge, separately billed multi-ball batches and the absence of a player verification workflow in the material we inspected.
We recommend the provider demo for learning these controls. Start with one standard Low ball, reconcile its cost and return in history, then compare risk versions. Only increase the ball count after calculating the full batch cost. If repeated drops make it difficult to stop, use the support options in our Australian responsible gambling guide.
