I’ve always enjoyed numbers, and I think that’s one of the main reasons I’ve always enjoyed darts. As a sports fan in general, numbers are everywhere.Stats about form, points needed to win a league, or what’s required to clinch a game. But darts is unique because every throw can be planned, and that plan is built around numbers.
Snooker is similar, but in snooker, the position of the white ball often dictates sacrificing a higher-value shot to keep a break going. In darts, the goal is simple:score 501 points and finish on a double, in as few darts as possible. There are exceptions, like setting up a shot when you have a big lead, but generally, the aim is maximum efficiency.
My first interest in marking darts games came when I was about eight or nine. At my local youth club, older lads would pay me in crisps or soft drinks to mark their games. I quickly noticed certain scores kept coming up. They were amazed I knew what 17 × 3 was, but I wasn’t adding it up,I just knew that segment was worth 51 because I’d seen it often.
The real challenge was adding three darts together and subtracting from the total. That took some maths at first, but after many games, it became second nature.
Fast forward to today, and I still love marking games. It’s fascinating because I’m always learning new finishing routes and setups. I’ve been lucky enough to mark on all the PDC Tours, and that sharpens you up fast. You need to call out totals almost instantly and, if asked, tell a player their finish just as quickly. Rhythm matters.
So, do you need to be a maths genius to do this well? In my opinion, no. People ask me that a lot, and I explain why: it’s mostly memory. You need some interest in numbers because memory works best when you care about the subject. When I was a competitive quizzer, I could remember Olympic champions or Oscar winners easily because I liked those topics. Birds and flowers? Not so much.
Marking darts is more about pattern recognition,almost like muscle memory. Do it enough, and it sticks. I know three treble 20s is 180 without adding 60 + 60 + 60. A more complex example: single 20, single 19, treble 18. I’ve seen it so often I know it’s 93 instantly. Over time, you build up a library of patterns. Oddly, I get caught out more on low numbers because they come up less often. The better the players, the easier it is because their scoring is more predictable.
The hardest part is telling players what they have left. That’s less about memory and more about quick subtraction. Tablets have made this easier compared to chalkboards, but speed still matters.
Predicting where a player will go next helps too. If someone has 116 and starts on 19, they’ll probably go treble 19 next (leaving 97). If they hit another single 19, they’re on 78, likely aiming for treble 18. Sometimes they surprise you with something like treble 14 to leave 36, so you add that to your mental playbook.
Players evolve, and routes change. Treble 17 is more popular now, and treble 14/double 14 pops up more often too. Like the game itself, marking takes practice. The more you do it, the more natural it becomes. Some players hate this part, which is understandable, but if you want to improve, there’s no shortcut - just keep doing it.
