Every 10 yards, you get another full 4 tries. Negative yard plays can happen. So, for instance, you begin at first down with 10 yards to go. If you gain 2 yards on that play, you now have second down and 8 yards to go. If you lose 3 yards on this play, you now have third down and 11 yards to go. If the offense doesn't go the original 10 yards in fewer than 4 plays, the defense gets the ball at that spot. A single play ends when the person with the football's knee touches the turf, regardless of who originally touched the ball, or if the ball is thrown forward and not caught. A ball thrown backwards but not caught does not end the play.
If the offense takes the ball all the way down the field, called a touchdown, they score 6 points, and then can choose to either try and run another touchdown in from 10 yards out for an extra 2 points (called a 2-point conversion) or kick a ball through the goalposts for 1 extra point.
Because the position on the field is so important in the game, a team may opt to kick the ball away on 4th down instead of trying to get the first down, which surrenders the series, but makes the other team start with the ball at the location the kick lands, rather than the spot of the 4th down. This is important because in football, the clock is a major factor in the game.
Going the length of the field to score a touchdown is a very time consuming process. Football consists of only 4 15-minute quarters, and the clock is constantly counting down, even between plays. An average drive - one that results in a touchdown, beginning at the 20 yard line - would consume about 6 minutes. That means you only really have time for 2 or 3 real successful drives in a single quarter of play. You will not score on every drive. To reward drives which get close to scoring, but not quite there, a team can opt to kick a field goal on 4th down, instead of trying for the first down or punting away. In this case, a kicker tries to kick the ball through the goal from the location of the last play. So if you're on the 40 yard line, staring down about a 55 yard field goal, you're basically asking your kicker to make up over half the field on one play. Kicking is hard and that's not desirable.
Now, to control the clock, teams have a few tools they can use. Any time they run the ball out of bounds, the clock stops. Any pass that isn't caught also stops the clock. Finally, each team has 3 time outs, which stops the clock, per half. In addition to the constantly running clock, there is also a play clock, which dictates how much time a team can spend between plays to line up and figure out what play to run. Teams have 40 seconds from the end of one play to run another play, or else they endure a penalty. Calling a time out stops the clock, and also gives the team 30 additional seconds to figure out what to do between plays.
That's all there is to football really. There are specific rules which dictate why some plays are illegal, but those can be picked up by watching the games. The strategy is what makes the game so great. There are libraries of books out there detailing the strategies offenses and defenses can employ, but really the best way to pick it up is to watch a game.
If you really want to give the sport a try, and I absolutely recommend it, you should watch the Texas vs Oklahoma game I posted above. It's considered one of the better games in football, and it wound up being an extremely exciting game.
