auth's RNG

roll for rarities, sell them, buy upgrades. an incremental RNG game.
auth's RNG is a web-based incremental RNG game. roll for rarities, sell them out, buy upgrades, wish upon the wishing well, and collect as many rarities as possible!

roll > sell > upgrade > unlock deeper systems > repeat!

this is the official android client, featuring:
- offline caching so the game loads without an internet connection
- a dedicated offline mode screen when you're fully disconnected
- haptic feedback on rolls
- performance improvements baked into the app layer
- a privacy-respecting build of the game (no third-party scripts)

inspired by roblox RNG games like sol's RNG and juke's RNG, but to be clear, this is not a roblox game!

disgustingly customizable. new customization features ship every update.
