Stairpong is a live physical race game by 155.io, available at MetaWin Casino. You bet on which color of ping-pong ball will reach the funnel first as 106 balls bounce down a real staircase, with five color options offering multipliers from 1.9x (White) to 95x (Pink). It has an RTP of 93.12% with a maximum win of 475x through Lightning Round multipliers, and player-controlled volatility through color selection.
Stairpong is a live physical game from 155.io, the studio behind a growing collection of real-time betting experiences. Rather than focusing on conventional casino graphics, 155.io builds games around physical events and live visual formats, allowing you to watch the action unfold as you bet. Stairpong is one of the developer's 12 games and sits alongside other live mechanical races and CCTV-based titles, including Marble, Footfall, and CCTV Rush Hour.

With Stairpong, 155.io has stuck to the simple gameplay it has become known for. 106 ping-pong balls in five different colors are released down a real staircase found in one of 155's studios. As the balls bounce, collide, and tumble towards the bottom of the stairs, you can watch to see which color reaches the funnel first.
Outcomes are physical and happen in real time, and you can watch the action unfold through a livestream with multiple camera angles. It is the basic and effective concept that has made 155.io one of the most talked-about new software development studios in the crypto casino world. Underneath all the visual style and live approach, the Stairpong game is essentially a straightforward pick-a-winner title and a racing game.
The five colors have different multipliers, showing their respective chances of winning. Choosing a higher-paying color offers a larger potential return but requires accepting greater risk. There is no rising multiplier to monitor and no need to decide when to cash out once the race begins.
Stairpong is available as part of the wider 155.io game environment here at MetaWin Casino. The software provider offers an in-game hub that allows you to switch between live feeds of games such as Marbles and Footfall, which are also supported at MetaWin.

Underneath all the visual style and live approach, the Stairpong game is essentially a straightforward pick-a-winner title and a racing game.

Our cryptocurrency deposits and withdrawals are near instant, allowing you to update your balance quickly as you play quick sessions. In total, we support over 25 tokens, including Bitcoin, Ethereum, Solana, USDT, and Litecoin.
When it comes to learning how to play Stairpong, this game has very easy rules. Open Stairpong from our games lobby or through the 155.io game hub if you're already in another game from the studio. The game shows you five ball colors, each with its own displayed multiplier. Before the betting period closes, choose the color you think will reach the funnel first and set your stake. Bets range from around $0.10 to $100, so there is plenty of room for both budget bettors and high rollers.
Once betting closes, 106 ping-pong balls are released down the real staircase. The race takes roughly 25 seconds in total, with the balls bouncing, colliding, and moving through the stairs before reaching the funnel. The live multi-camera setup lets you follow the physical action rather than watching an animation showing a virtual race.
If the color you chose reaches the funnel first, your payout is automatically settled according to its multiplier. If another color wins, your stake is lost. It also doesn't matter if your color lands in the funnel after another color - only the first color wins. Stairpong is designed to work on mobile as well as desktop, since it's built on HTML5 technology, so you can watch the live race and place your color selection from a smartphone or tablet.
Stairpong's mechanics are deliberately simple, with 106 ping-pong balls split across five colors that race down a step track towards a funnel. Your objective is equally straightforward: just predict which color ball will win the race and go into the funnel first. All balls are randomly shuffled in a bucket before the round starts, with each color carrying fixed odds displayed before you place your bet.

The five selections have different payout multipliers. White pays 1.9x, Orange 2.37x, Green 9.5x, Blue 19x and Pink 95x. The higher multipliers reflect the lower probability of those outcomes, making Pink the highest-risk, highest-payout selection. Some balls have lower multipliers than others because there are more of them, so they are more likely to win.
The standard maximum payout is 95x, although a Legendary Lightning Round can boost an eligible selection by up to 5x, taking Pink to 475x. The live presentation lets you follow the balls as they bounce and tumble down the real stairs, with multiple camera angles providing a view of the action. The round lasts roughly 25 seconds in the typical presentation, making Stairpong a quick game that rests on the single "which will win" decision.
There is no mid-round cash-out and no Forecast or Tricast market. Stairpong has a single Winner market, with the first ball to enter the funnel determining the result.

The higher multipliers reflect the lower probability of those outcomes, making Pink the highest-risk, highest-payout selection.
The Stairpong RTP is 89.62% at base level, while its RTP ranges from 90.62% to 91.64% at player level 0, depending on whether there is a Lightning Round. While the Lightning Round brings random payout boosters, you shouldn't consider them as part of the normal payout cycle.
Volatility depends largely on the color you choose. White pays 1.9x and Orange 2.37x, making them the lower-payout selections, while Green pays 9.5x and Blue 19x. At the other extreme, Pink pays 95x, offering a much larger potential return but has the least chance of success.
This makes Stairpong a choose-your-own-risk kind of game. Choosing one of the common, lower-paying colors gives you a smaller potential win in exchange for a bigger chance of success, while backing Pink means accepting much more variance for the chance of a much larger payout. Lightning Rounds can temporarily boost eligible multipliers, adding another layer of possible variance.
Building a proper Stairpong strategy is more about controlling your budget and understanding game mechanics rather than hunting for magic formulas to "beat" the game, which is impossible.
If you want better control over your budget as you play, we recommend taking advantage of our responsible gambling tools here at MetaWin Casino to set clear limits.
Stairpong and Marbles are similar titles within the 155.io catalog because both turn physical, real-world races into simple winner betting. The big difference between the games is the race physics. Stairpong sends 106 ping-pong balls down a staircase, while Marbles encompasses four separate marble-racing games, with different numbers of marbles, racecourses, and betting markets depending on the track you choose.
| Feature | Stairpong | Marbles |
|---|---|---|
| Provider | 155.io | 155.io |
| RTP | 89.62% base | 87.81%-96.47% depending on bet |
| Format | Live mechanical ball race | Live marble races |
| Bet Type | Pick the winning color | Winner, Forecast, and Tricast |
| Max Multiplier | 95x base, up to 475x with Lightning | Up to 288.96x base, up to 1,444.8x with Lightning |
| Basis | Live physical race | Live physical races |
| Mobile | Yes | Yes |
Stairpong is the simple choice if you prefer making one color selection and watching a short physical race, with no need to consider finishing-order combinations. Its five multipliers also make the risk-versus-reward difference between selections visible.
On the other hand, Marbles offers a greater variety. Marble Plinko and Rolling Dunes include Winner, Forecast, and Tricast markets, while Snake has Winner and Forecast betting, and Survivor uses a single Winner market based on the last marble remaining. That makes Marbles better for players who want more ways to bet on a race.
