The developer behind the wildly-addictive Candy Crush puzzle game is seeking a listing on the New York Stock Exchange.
Millions clock in daily to test their skills in the game, which involves lining up tiny pieces of coloured sweets to make them vanish from the screen of their computer or mobile phone.
King Digital Entertainment said it had asked the US Securities and Exchange Commission regulatory body for a listing.
King hopes to raise some $555 million, according to an estimate in its SEC filing - although similar IPOs have raised much more.
Candy Crush - King's top-selling game - started life as a Facebook game in 2012 but can also be played online and on smartphones.
The highly-addictive game is free, but players can pay for in-app extras to help them pass up through its more than 500 levels.
"This is a medium-sized business, with a global business model," explained Laurent Michaud, video games expert at IDATE.
"They have reached a plateau. The initial public offering is a response to their need to pursue their international development."
Candy Crush records some 700 million sessions a day and racks up daily sales of $943,658, according to the IDATE digital research and consultancy firm.
Thirty percent of Candy Crush players quizzed in a survey last year called themselves "addicted", while 67 percent said the game had impacted on their lives in some way -- distracting them from work or household chores.
A quarter of players said they had spent money on the game, according to market research firm Ask Your Target Market.
King Digital has come under fire for trademarking the word "Candy" in the European Union and has filed for a similar trademark in the United States.
Its chief executive Riccardo Zacconi defended the move last month, saying it was merely to stop copycats cashing in on Candy Crush's success.
It claims to have 324 million monthly unique users for 180 games in 14 languages, available through its King.com website but also on mobile platforms run by Apple, Google and Amazon, and on Facebook.
King Digital's planned float is the latest in a series by Internet and gaming firms over the past three years, the most high-profile being Facebook and Twitter.
Recent tech sector IPOs:
Twitter hit Wall Street with a bang in November, with opening gains of some 70 per cent for the one-to-many messaging service as it raised more than $2 billion.
But some of the enthusiasm faded after Twitter's first earnings report showed tepid growth in its user base. Twitter shares opened Tuesday at around $64, more than double the offering price but well below highs above $77 in December. Its market value is around $23 billion.
The social network started by Mark Zuckerberg now has more than 1.2 billion users around the globe.
It had a rocky debut after it went public at $42 a share in May 2012, raising $17 billion in the biggest tech IPO on record.
Facebook shares fell by more than half in the ensuing months, but then recovered to hit record highs in recent months, bolstered by strong gains in mobile ad revenues.
The stock opened Tuesday above $73, giving the leading social network a market value of some $187 billion.
The social network for professionals and job-hunters, LinkedIn has been one of the biggest stars of the technology sector since turning to Wall Street in May 2011.
LinkedIn raised $391 million in its IPO, and has seen a spectacular gain in its share price, from $49 on the first day. Shares opened above $206 Tuesday, equating to a market value of around $26.64 billion.
GROUPON
Online daily deals sensation Groupon went public in November 2011, raising $777 million in what at the time was the biggest IPO by an Internet company since Google.
But the Chicago-based company, which was listed on the Nasdaq at $22 has struggled since then and its share price has been hovering around $11 for a market value of $7.55 billion.
YELP
Shares of restaurant and business review website Yelp have soared since the San Francisco-based company went public in March 2012 with a $16.65 initial public offering price, raising $127.67 million.
Boosted by reports of cooperation with Yahoo, Yelp shares were trading at around $99.92 on the New York Stock Exchange on Tuesday, representing a market capitalization of $6.88 billion.
PANDORA
Internet radio giant Pandora Media made its Wall Street debut in June 2011, raising $235 million with stock priced at $17.76 a share.
Pandora, which creates personalized radio stations for users based upon their favorite artists or songs, has been gaining despite intensified competition from the likes of Apple, Google, Spotify and others. It rose Tuesday above $41.08 a share, giving it a value of $8.10 billion.
ZYNGA
Online gamemaker Zynga was valued at $7.77 billion when it made its play on the stock market in December 2011, raising $1.11 billion from investors.
But the company behind Facebook games such as FarmVille and Mafia Wars has been on a roller-coaster ride since then.
