Idle Oil Well is a portrait-oriented idle clicker game focused on passive progression. Players manage oil wells, earning currency over time that can be reinvested to upgrade production. The game is designed for short, interruptible sessions, but progression can feel gated by frequent advertisements and optional in-app purchases, which some players feel are necessary for faster advancement.
