Castile is an AAA-quality rogue-like idle card RPG set in a fantasy Cthulhu universe, developed by Nytro Lab. The project has successfully raised $8 million from investors including HashKey Capital, OKX Ventures, Aptos, and Amber Group. Recently, Castile launched its beta test for the game campaign, offering testers a chance to share a prize pool of 6 million $CAST tokens along with in-game bonuses. This beta test will only last for a month, so it's advisable to participate as soon as possible.
