I feel like it’s about climbing that leaderboard. You usually get a set amount of time or spins, and the goal is to rack up as many points (or wins) as you can within that window. It turns solo play into a bit of a race, and the adrenaline can be real in the final minutes. Also, check if your casino has daily or weekly tournaments, some platforms like Playfina which gave me 200 free spins on sign-up, keep in mind that as well.
