Why Strategy Games Work So Well in a Browser
Strategy games are a natural fit for browser play. They typically rely on mouse clicks rather than fast reflexes, work well in a windowed tab, and often support pause or async play — meaning you can think through your moves without time pressure. Whether you love tower defense, turn-based tactics, or real-time strategy, there's a solid lineup available for free right now.
