A kids game called Jungle Run that, until recently, was available in the Apple App store, was secretly a cryptocurrency-funded casino set up to scam people out of money. Kosta Eleftheriou, a tech entrepreneur and founder of the Apple Watch keyboard app FlickType, found the scam. Jungle Run was marketed in the App Store as a game for ages 4+. The same developer also had Magical Forest Puzzle on the app store, which used the same VPN trick to unlock a different casino.
