Casual games developer King.com will be releasing both Candy Crush Saga and Bubble Witch Saga in the Japanese and Korean markets, the company announced in a press release. The games will launch first on the Facebook platform, with iOS and Android versions expected to follow shortly after.

After years of Zynga sitting comfortably atop the daily active user (DAU) charts for Facebook games, King.com’s Candy Crush Saga has taken the lead, boasting over 9.7 million daily players. FarmVille 2,  in comparison, is currently in second place with 8.8 million DAUs.

Hot off the heels of publishing Bubble Witch Saga and Candy Crush Saga on iOS, King.com has announced that both games are now available on Android. This marks the third platform the games are playable across, meaning players can fire them up on iOS, Android or Facebook, and continue playing them elsewhere with their save intact.

In the casual world, convenience is one of the most powerful tools in a developer's arsenal. It can make or break the install base of a game, and a lack of it can inspire people to quit playing. After all, they can exit out and be playing something new in a matter of seconds. How does one prevent that? Offering a compelling cross-platform experience is one possible solution, and King.com has done just that by synchronizing the Facebook version of Bubble Witch Saga with the recently released iOS version.

King.com CEO Riccardo Zacconi’s talk at this year’s Casual Connect revolved primarily around how best to create a compelling multi-platform experience. And he wasn’t just preaching the importance of ports, either. In his eyes, if you want additional control over how long people play your game and how much they spend, you’d better weave in some kind of social features or cross-platform play.

2012 has been a pretty big year for King.com. Not only have they been banging out hit after hit (Candy Crush Saga, Pyramid Solitaire Saga, etc..), but they cumulative catalogue has seen them rise to the top of the App Store charts. They’re now in the #2 spot in terms of Facebook game makers according to AppData.com, with a whopping 52 million gamers playing every month. Now it looks like they want to climb to the top of the App Store, too.

King.com has announced that social puzzler Bubble Witch Saga is the latest Facebook hit to make the move to Google+.

Developer King.com has announced that its games, which span mobile, Facebook, and online, are now being played more than a billion times a month. This puts King.com amongst the top 10 developers on Facebook, and the developer is continuing to expand with new games in the works and the opening of two new offices in San Francisco and Romania.

The number of Bust-a-Move-style bubble games on Facebook continues to grow at an exponential rate, making it increasingly hard for any one game to stand out. King.com's Bubble Saga managed to do just that thanks to a clever and unique physics-based take on the genre, and the similarly titled Bubble Witch Saga attempts to do the same with ... witches. There isn't anything new here in terms of gameplay, and the experience actually feels like a step back from Bubble Saga. That's not to say that Bubble Witch Saga is a bad game, as it's solidly crafted and visually polished, but it's also not any different than all the other bubble games out there.
