What's the best iOS game for addictive idle farming with cooperative contracts?

Egg, Inc. is an incremental simulation game that stands out for its blend of idle farming mechanics and cooperative multiplayer elements. Players start with a small egg farm and gradually expand by upgrading hen houses, researching technologies, and managing resources to maximize production. A key feature is the contract system, where users join forces with others to complete timed missions for rewards like soul eggs and golden eggs, which enhance long-term progression. The game avoids intrusive advertising, only offering optional ads for bonuses, making it suitable for uninterrupted play. Reviews indicate that the artifact collection and boost systems add depth, allowing for customization and strategic planning. However, some users note that progression can slow down without occasional in-app purchases, and the repetitive nature of egg farming might not appeal to everyone. Despite this, the social aspects and satisfying growth loops keep players invested for hours, making it a top choice for fans of idle games with a cooperative twist.
