Despite being more than a year old, and racking up more than half a billion downloads, it seems that the world is still not bored of Candy Crush, the match-three game that has players of all ages addicted.

Recently, the Candy Crush Saga app and its developers, King, have hit the headlines, first for attempting to trademark the words 'candy' and 'saga', and more recently for trying to sue the developer of the app it appears to have copied.

Developer Albert Ransom recently published an open letter on his website, sparked by King's attempt to rid him of his trademark by purchasing the rights to an older game called Candy Crusher. The letter accuses King of copying his app, and claims Candy Crush Saga is a "knockoff" of his 2010 game CandySwipe.

Ransom points out that the Candy Crush Saga icon, the candy itself and the written encouragements within the app are all very similar to those used in his CandySwipe app, which was released two years before Candy Crush Saga existed.

"You have taken away the possibility of CandySwipe blossoming into what it has the potential of becoming," Ransom writes. "I have been quiet, not to exploit the situation, hoping that both sides could agree on a peaceful resolution. However, your move to buy a trademark for the sole purpose of getting away with infringing on the CandySwipe trademark and goodwill just sickens me."

CandySwipe is still currently available to download free from the iOS App Store, and many reviewers of the game seem to have boycotted Candy Crush Saga after reading Ransom's open letter and downloaded CandySwipe instead. It needs a bit of a update when it comes to the visuals, but overall it's a fun, free match-three app that's worth a try.
