I’m trying to understand which gambling options let me use strategy (like poker or blackjack), and which are purely based on luck (like slots or lotteries). A breakdown would help me play smarter.

That distinction is clearly covered at https://casino.spot/blog/gambling-types-and-casino-games/. The post explains that classic casino games such as roulette or slots rely entirely on chance and come with a house edge. In contrast, skill-based games like poker or strategic variations of blackjack offer players the chance to influence the outcome. And lotteries or raffles are pure luck—no strategy involved. Even sports betting mixes entertainment and skill, especially when odds and research come into play. It helped me recalibrate my expectations and choose games based on whether I want relaxing fun or a thoughtful challenge.
