The game itself is fairly simple; it’s just that it’s existed in codified form for like 140 years and they have had to make rule adjustments in every era to account for the next game-breaking strategy, so the corpus of rules is huge.
Each team gets up to nine turns on offense. If the home team (which would be on offense in the second half of the ninth inning) is ahead when their final turn on offense would occur, the game ends.
Each batter gets pitched to until they hit the ball in-bounds, they get three strikes, or they get four “balls”. A strike occurs when a hittable ball (over home plate, between the batter’s knees and shoulders, as a rough approximation) goes past the batter with no attempt to hit, or when any ball is swung at by the batter without a successful hit in-bounds (so, foul balls are counted as strikes, except that you can’t strike out on a foul - however, if you do hit a foul ball and a defender catches it before it hits the ground, you are out). Almost all other pitches [0] are “balls”, and after four balls the player automatically advances to first base.
Getting all the way back around to home plate scores a point.
After the defending team gets three outs against the batting team, they switch roles.
There are a lot more details and nuance, but that’s baseball in a nutshell.
