Nuclear Tycoon: Idle Reactor

This is a solo, portrait-oriented idle clicker game with mindless gameplay and high replay value, suitable for short, interruptible sessions. Monetization is problematic, with many users reporting that paid 'no ads' options do not work and progression is heavily ad-dependent, making it feel pay-to-win. It's best for players who enjoy passive progression and don't mind a potentially frustrating monetization model.
