On 28 February 2012, an in-game feature was introduced called the "Squeal of Fortune" that allowed players to win items on a daily basis by spinning the wheel.  On 2 April 2012, it became possible for players to spend real-world currency in exchange for additional spins, introducing a form of microtransaction to the game.  Jagex CEO Mark Gerhard had previously described microtransactions as "a stealth tax", and the update provoked complaints from players who believed they had been "betrayed" by the change.  In July 2012, Jagex released Solomon's General Store, making it possible to spend real currency in exchange for "RuneCoins" that could be spent on cosmetic rewards in the game.  On 29 August 2012, Gerhard released a response to this controversy, describing these microtransactions as "[having] a significant role in ensuring that we can continue to support, develop and grow the game for many more years to come. " He states that while these decisions are "not necessarily popular", they are made with the future of RuneScape in mind.  On 4 February 2014, the Squeal of Fortune was replaced with Treasure Hunter. Rather than spinning a wheel for prizes, players are given keys which are used to open a chest of their choosing.  On 26 March 2014, Gerhard reiterated his stance on microtransactions and their importance in updating RuneScape, and announced a partnership with Supersonic ads, allowing players to earn RuneCoins by watching advertisements or sampling products.
