The Plinko RTP refers to the proportion of all wagers that are returned to players after a large number of rounds have been played; it gives no information regarding a single session, yet it is the most useful single figure when comparing different versions. This analysis includes the RTP, odds, multiplier and payout figures as reported for the Plinko games on 1xBet, in the 1xGames version provided by the company itself and in the versions supplied by the software providers. Our approach is straightforward: if a provider gives a figure, we use it and indicate where it comes from; if only a secondary website reports the figure, we make that clear and present a range instead of a single value; if no figure is available, then we leave the entry blank. Each number is marked so that it can be verified using the live client, since casinos may adjust the games in a way that differs from the provider's standard release. This information does not allow any prediction of individual results. Only for people 18 years of age and over; gambling carries a risk of loss.
Plinko RTP by Provider
The table gives the RTP figures that have been reported for the Plinko games on 1xBet together with the source of each figure; figures published by the provider are indicated as such and those from other sources are described as secondary.
| Version | Reported RTP | Type of source | Source | Status |
|---|---|---|---|---|
| BGaming | 99% | Provider page | bgaming.com | Verify in live client |
| Spribe | 97% | Secondary | galaxyofslots.com | Verify in live client |
| Turbo Games titles | 85–96% | Secondary | plinko1.in | Verify in live client |
| 1xGames (in-house) | Not published in accessible sources | None | None | Verify in live client |
| 1xBet Plinko catalogue, average | About 96.9% | Secondary | onlineplinko.com | Verify in live client |
There is a contradiction in the data. On the one hand, certain sources state that Spribe's RTP can be set as high as 99%, which contradicts the 97% figure given. The most probable explanation is that a casino can select a setting within the provider's range, although we were not able to verify this. Secondly, the average cited by onlineplinko.com is unstable since the page displays two slightly different averages, and therefore we quote the figure as "about 96.9%" and no more. Moreover, calculating an average over the entire catalogue masks the difference between the best and worst versions.
What RTP stands for. RTP, which is short for return to player, represents the proportion of all the money that a game pays back over a very large number of rounds. If the RTP is 99%, then for every PKR 100 that is staked an average of PKR 99 is returned, so the house keeps PKR 1; if it is 97% the house keeps PKR 3, and when the figures in the range from 85 to 96%, which apply to the Turbo Games titles, the house keeps between PKR 4 and PKR 15. These are averages over millions of rounds. A single session may end considerably above or below these averages, and the RTP does not allow prediction of the next ball.
The RTP does not provide information on how frequently a version makes a payment or on the size of the fluctuations, since this varies according to the rows and the risk level. With regard to the 1xGames version, there is a gap in the table: as it does not have a published RTP, it cannot be compared with the other games. Before placing any trust in the figures given here, make sure you read the rules panel of the specific title you have opened.
Plinko Odds: The Binomial Math of Slots
The probabilities involved in a Plinko board can be derived from a single model: each peg causes the ball to bounce either to the left or to the right with equal probability, approximately 50/50. When the board has n rows, the ball undergoes n bounces, and the slot that it ends up in depends on the number of bounces that go to the right. The number of different paths that lead to a slot with k right bounces is C(n,k), there being 2^n possible paths in all, so:
Probability of a slot = C(n,k) / 2^n
Here is an example with 16 rows. Since there are 16 rows there are 2^16 = 65,536 possible paths and 17 slots; the table gives the slots from the left edge to the centre and the right side mirrors this.
| Slot from the edge | Paths | Probability |
|---|---|---|
| 1st (edge) | 1 | 1 in 65,536 (about 0.0015%) |
| 2nd | 16 | About 0.024% |
| 3rd | 120 | About 0.18% |
| 4th | 560 | About 0.85% |
| 5th | 1,820 | About 2.8% |
| 6th | 4,368 | About 6.7% |
| 7th | 8,008 | About 12.2% |
| 8th | 11,440 | About 17.5% |
| 9th (centre) | 12,870 | About 19.6% |
The figures indicate that the centre slot occurs about once in every five drops, while the edge slot appears once in every 65,536 drops. For either edge — whether the left or the right — it happens approximately once in every 32,768 drops. These are the slots that have the high multipliers mentioned in the headlines, which is the reason why a 1,000x payoff is a rare occurrence and not something that is aimed for.
The point at which the model ends is that this is an idealised version of the situation, based on the assumption that each bounce off a peg is fair. In an actual game, simulation of the pegs may not take place at all; instead, many games use a random number generator to select a slot, the probabilities for that slot being determined by the provider and chosen so as to achieve the published RTP. The binomial pattern is a helpful indication of the shape of the payout rates, not a guaranteed description of any specific version. Since we were unable to verify the slot probabilities for the 1xGames version, we regard these figures as applying only as a model and refer to the game's own rules panel.
Plinko Multiplier Distribution
The figure shown under each slot is the plinko multiplier, and it is multiplied by the amount you have staked; for example, if you have a 2x slot you get twice your stake back and if you have a 0.5x slot you get half your stake back. Along the strip the multipliers obey a single rule: the lower the probability of a slot, the higher the multiplier. The slots located in the edges, which the odds table mentioned above gives as about one in tens of thousands on a 16-row board, have the highest multipliers, while the slots in the centre, which occur about once in five, have the lowest.
The in-house 1xGames version has a reported range extending from 0.2x to 1000x (1xbetbookmakers.com; check in the live client). As stakesim.com states, a BGaming-style board at high risk reaches a maximum of nearly 29x on eight rows and 1,000x on sixteen rows (verify according to the version). The strip's value is determined by the game, while the risk level determines the rate at which it increases.
The way the strip ends up as an RTP is that the return from the board is equal to the sum, taken across all the slots, of each slot's probability multiplied by its multiplier. Each slot contributes a small amount to the total and the middle slots contribute a great deal since they are so frequently hit. The rare slots located at the edges add only a minor portion even though they have a very high multiplier. As a simple example, if the central slot on a 16-row board paid out 0.5x, it would contribute approximately 0.098 of each stake to the return (that is 19.6% times 0.5). This is an example based on calculations, not something that actually happens in a real strip.
Why Center Slots Pay Less
There are two reasons. The first of these is how often this happens: since the ball tends to land in the centre most frequently, a high multiplier in that area would cause the RTP to rise rapidly. In order to maintain the RTP at the level it has been published, the provider therefore sets the centre value low, usually below 1x. The second reason is about balance: the low payouts when landing in the centre cover the high edge payouts. A player who lands in the centre receives the more common and smaller payment, which in turn funds the rare and larger one.
Plinko Max Win: 555x vs 1,000x vs Higher Caps
The highest possible win in Plinko is determined by the greatest multiplier on the strip; it acts as a ceiling rather than being a common outcome. The table lists the ceilings that have been reported for the versions on 1xBet.
| Version | Max multiplier | Source | Status |
|---|---|---|---|
| Spribe | 555x | galaxyofslots.com, onlineplinko.com | Verify in live client |
| BGaming | x1,000 | bgaming.com | Verify in live client |
| 1xGames (in-house) | Up to 1000x | 1xbetbookmakers.com | Verify in live client |
555x vs 1,000x. Although the difference between the two figures listed appears to be big, it is less significant than it seems. If the stake is PKR 100, the top prize is PKR 55,500 at 555x and PKR 100,000 at 1,000x. In either case, the ball has to land in an edge pocket on a long board where the risk is high. With a 16-row board this means a chance of about one in 65,536 for each edge, or about one in 32,768 if either of the two edges pays the maximum amount. At such odds, the difference between 555x and 1,000x has almost no effect during a typical session.
Greater limits. Among the sources that we have consulted for this article, we have not come across a higher ceiling. It is possible that a multiplier exceeding 1,000x could be found in other versions or in casino promotions, but we are unable to verify this. Exercise care when seeing pages that advertise a considerably higher maximum without naming the provider, the board, and the risk level.
Go through the small print. The maximum multiplier does not necessarily mean the same as the maximum payout. It is important to check the rules panel and the terms to see if there is a limit on the amount paid in each round, since the casino might impose such a limit. Additionally, you should bear in mind that the maximum amount depends on the settings: as has already been mentioned, an 8-row board with high risk is capped at near 29x (stakesim.com; verify this according to the version).
Plinko Payout in PKR: Expected Value Tables
A plinko payout equals your stake times the multiplier of the slot in which the ball lands, and two simple tables illustrate how this works in rupees. The tables use rounded PKR amounts for illustrative purposes only and do not indicate how much to stake.
Table 1: payout for one drop at a PKR 100 stake
| Slot multiplier | Payout in PKR | Note |
|---|---|---|
| 0.2x | 20 | Lowest value reported for the in-house version (1xbetbookmakers.com) |
| 1x | 100 | Stake returned, no gain |
| 29x | 2,900 | High-risk ceiling reported for 8 rows (stakesim.com) |
| 555x | 55,500 | Spribe maximum (galaxyofslots.com) |
| 1,000x | 100,000 | BGaming maximum and in-house ceiling (bgaming.com, 1xbetbookmakers.com) |
Table 2: long-run expected result by RTP
| RTP | Expected return on PKR 1,000 staked | Expected loss |
|---|---|---|
| 99% | PKR 990 | PKR 10 |
| 97% | PKR 970 | PKR 30 |
| 96.9% (catalogue average, onlineplinko.com) | PKR 969 | PKR 31 |
| 96% | PKR 960 | PKR 40 |
| 85% | PKR 850 | PKR 150 |
To read Table 2, remember that the amount refers to the total that has been staked over many drops, not the amount from a single drop. It represents an average calculated over a very large number of rounds. A real session consisting of a few dozen drops may end either well above or well below these figures, and even if you are on a run of losses, this does not make a win more likely. The 1xGames version provided by the house has no published RTP and so it is not included in the table.
What the tables together indicate. As Table 1 illustrates, it is this headline multiplier that draws the attention. Table 2 shows the cost of playing: a version with a lower RTP requires a greater amount of each stake over time. Since both tables are based on figures from public sources, you should check the RTP and the multipliers in the live client.

Only people aged 18 and over are allowed. Since gambling involves a risk of loss, you should establish limits and get help if it ceases to be enjoyable.
