Seventeen Laws sounds like seventeen things to memorise. It is closer to three questions asked over and over. **Is the ball in play?** — because nothing else matters until it is. **Was there an offence?** — which is almost never about what happened, but about how it happened and where. **What restarts play?** — the answer that actually costs you if you get it wrong, because a correct decision restarted the wrong way is still a mistake. Read every chapter here against those three, and the Laws stop being a list and start being a decision tree. Descriptions follow the IFAB Laws of the Game 2026/27; a competition may modify some of them, which the last chapter covers.
Each chapter opens with the short version. Tap one to read the detail.
The field, the ball, and why lines belong to their areas
~2 min
The field's markings are not decoration — each line is part of the area it bounds, which decides handball inside the penalty area, offside at the halfway line, and whether a ball has left play. Get the geometry right and several judgement calls answer themselves.
Players and equipment: safety first, then uniformity
~2 min
Equipment decisions are safety decisions, not tidiness decisions. The referee's test is whether an item is dangerous to anyone, and jewellery is the case officials most often let slide and most often regret.
The referee's authority — and its limits
~2 min
The referee's decisions on facts connected with play are final. That power is broad, and its most useful limit is time: a decision can be changed only before play restarts, which is why the restart is the real deadline in officiating.
The rest of the officiating team
~2 min
Assistants, fourth officials and video officials advise; the referee decides. Knowing exactly what each is positioned to see is what makes their input useful rather than noise.
Time, ball in play, and how a result is reached
~2 min
Playing time is the referee's to manage, and the clock is not the authority — allowance for time lost is added at the referee's discretion. A result is reached by goals scored while the ball was in play, which is why "in play" is the first question in every scoring decision.
Restarts share a grammar
~2 min
Kick-offs, throw-ins, goal kicks, corners, free kicks and dropped balls look like six different rules. They are one pattern with variations: who restarts, from where, when the ball is in play, and who may not touch it next.
Restart rulings that actually come up
~2 min
Most restart disputes are about position and encroachment rather than about which restart was correct. Knowing the required distance and where the ball must be placed resolves nearly all of them on the spot.
Offside: position is not an offence
~2 min
Being in an offside position is not an offence. The offence exists only when a player in that position becomes involved in active play — and separating those two ideas resolves most offside arguments before they begin.
Fouls and handball: how, not what
~2 min
A foul is not defined by contact but by the manner of it — careless, reckless, or using excessive force. Handball turns on whether the arm made the body unnaturally bigger, which is a question about the arm's position, not about intent.
Cards: what they are actually for
~2 min
Cautions and sending-offs are tools for match control, not scores settled with individual players. Each has a defined set of triggers, and using them for anything else costs you the control they exist to protect.
Advantage and reading the game
~2 min
Advantage lets play continue when stopping it would punish the team that was fouled. It is a judgement about what happens next, taken in about two seconds, and taking it wrongly is worse than not taking it.
Competitions change things — know which things
~2 min
The Laws allow competitions to modify specific matters, and separate protocols exist for temporary dismissals, return substitutes, concussion substitutions and more. Officiating a match means knowing which set you are under before kick-off.
