Polo has a reputation for being impossible to learn from the outside. The rulebook is written to be precise rather than readable, the fouls are spatial and hard to picture, and nobody explains what the numbers on the shirts mean.
This is the answer to all three.
The rules, properly
550 questions across grass and arena polo, from the HPA Blue Book 2026 and Green Book 2025. Every answer tells you the rule it comes from, in plain English first and in the published wording underneath.
What is the call?
111 situations drawn on the pitch. The ball crosses the back line off a defender's own pony: hit-in or Corner 60? A hook across the pony: legal or a foul? Two players on the exact line, one with the ball on their offside: whose line is it? You decide, then the rule that settles it comes up. Twenty-five of them are on right of way alone, because that is the judgement the whole game turns on.
See the fouls
Crossing, the line of the ball, right of way, riding off, the penalties, the Corner 60 and the advantage rule, all animated on the pitch. Fouls make far more sense from above than they do read off a page.
Tactics
What each of the four positions does. Who marks whom, and why it is inverted. Winning the throw-in, taking a knock-in, defending a 60, turning the ball off the boards, making it two on one. How handicaps really work, and where the umpires stand. Twenty-six plays, all animated.
Mock umpire exam
Forty questions across every section, thirty minutes, eighty per cent to pass, scored section by section.
Glossary
Fifty-eight terms, from chukka to the Hancock Zone, each tied to the rule that defines it.
Built to teach
What you get wrong comes back on a widening schedule. Weak spots are drilled automatically. Progress is broken down by section.
No sign-up, no connection needed
All of it lives on your phone and works in the middle of a field with no signal, which is where you want it.
