Idle Millionaire is the ultimate incremental business simulation, taking you on an entrepreneurial journey from running a tiny lemonade stand to managing a global corporation. Invest profits into faster production lines, hire managers who operate businesses automatically, and unlock entirely new revenue streams — from food trucks and factories to real estate portfolios and tech startups. Prestige mechanics let you reset progress for powerful permanent multipliers, creating an endlessly satisfying loop of growth. Smart upgrade decisions separate casual players from efficiency-maximising players who reach billionaire status in record time.
Click your business to generate income. Use coins to upgrade businesses and hire managers. Managers automate income. Reinvest strategically to grow faster.
