About us

Open Games is a new, founder-funded B2B games studio building original, high-volatility online casino games for the real-money iGaming market. We'll distribute through leading aggregators to operators worldwide, and we're assembling a small, senior founding team in Bulgaria — offices in Sofia and Plovdiv, remote-friendly across the country. Our plan is deliberate: ship a tight portfolio of genuinely distinctive games, win on math and art, and grow with the people who built us. Join now and you're not employee #200 at a corporation — you're a founding voice with real ownership of the product.
