Launched on the App Store in 2013, but then banned for its use of Bitcoin, monkey flinging mobile game SaruTobi is back on iPhones, with the claim that it’s the first iOS game to integrate in-app purchases using Bitcoin. The technology works on ZBD’s Bitcoin-based payment system, which uses the Lightning network to enable fast, crypto micro-payments. Famously, satoshis are Bitcoin’s base currency unit, with 1 Bitcoin consisting of 100 million sats.
