Strategy games test planning, resource management, and tactical thinking. Browser strategy games range from casual tower defense (Bloons TD 5) to deep competitive chess. No console or gaming PC required — these games run beautifully in any browser.
Good strategy gamers think multiple moves ahead. In tower defense games, plan your entire build order before placing the first tower. In chess, consider your opponent's best response to each of your moves. The habit of forward-thinking improves gameplay across every strategy genre.
