Hi, I'm Jeco.
I am a speedcuber from Hong Kong. I started when I was nine, and I'm 18 now. I've been competing in official WCA competitions since 2019, with 11 competitions so far. My strongest event is the 4×4, where I rank 11th in Hong Kong.
When I was a kid learning the cube, I couldn't find anyone to coach me. I teach today so the next generation has the guidance I never had, and to help the sport grow by bringing this hobby to more people. Over the past year I've taught more than 70 students, in English and Cantonese.

More than a toy
What kids take away from learning the cube goes well beyond the cube itself.
Less time on iPads
A cube fits in a pocket and needs no battery. It gives kids something to reach for in the car, at a restaurant or after school that isn't a screen.
Sharper critical thinking
Every solve is about spotting patterns and planning ahead. Kids practise breaking one big problem into small steps they can handle.
Real confidence
Solving a cube looks impossible until the day they do it. That first solve, and every personal best after it, is something they earned themselves.
A way to relieve stress
Turning a cube is absorbing and calming. It gives busy hands and a busy mind somewhere to settle after a long school day.
Focus and patience
Getting faster takes practice. Kids learn to stick with something hard and to try again after a mistake.
Memory and coordination
Learning move sequences until the hands know them by heart exercises memory and hand-eye coordination together.
Three stages, one cube at a time
Rubik's Cube lessons and tutoring in Hong Kong, 1-to-1 or in small classes. From age 3 to adult, every student starts where they are. Some have never finished a side; some already solve it and want to get fast.
First solve
Learn how the cube actually works, then solve it layer by layer with a beginner method that sticks. The goal: a full solve, on their own, without notes.
Getting fast
Finger tricks, look-ahead and the CFOP method that most speedcubers use. We time every session so kids can watch their own average drop.
Competition ready
How official WCA competitions run: inspection time, timers, judging and nerves. Plus other events like 2×2, 4×4 and bigger cubes for kids who want more.
HKU University Hall
Feel free to message me if you want the classes to be held in another location.
Questions parents ask
What age can my child start Rubik's Cube lessons?
I teach students from age 3 up to adults. Younger children start with how the cube moves before learning a full solve.
Does my child need to know how to solve the cube already?
No. Complete beginners start at the first stage and work towards solving the cube on their own. Students who can already solve it go straight to getting faster.
Where are the lessons held?
Lessons are at HKU University Hall on Hong Kong Island. Message me if you would like classes in another location. Online lessons are also available.
Are lessons 1-to-1 or in a group?
Both. You can choose 1-to-1 coaching, a small group class, or online lessons.
Which language are lessons taught in?
English or Cantonese, whichever the student is more comfortable with.
How do I book a trial lesson?
