Ritangle Mathematics Competition

Ritangle Mathematics Competition (Ritangle) is an international online mathematics competition organized by the University of Oxford. Designed for middle and high school students around the world, the competition combines mathematical problem-solving with coding, logical reasoning, and collaborative learning. Ritangle aims to encourage students to explore mathematics creatively while developing analytical and computational thinking skills in an interactive online environment.

Ritangle is conducted entirely online and usually takes place over several weeks. Participants solve a series of mathematical challenges that gradually increase in difficulty and often involve elements of programming, pattern recognition, and logical deduction. Students may participate individually or as part of a school team depending on the competition structure for a given year. The competition emphasizes sustained problem-solving and independent exploration rather than speed-based testing.

The competition helps students strengthen mathematical reasoning, computational thinking, logical analysis, coding-related problem-solving, and creative thinking skills. Ritangle encourages participants to approach unfamiliar problems through experimentation, persistence, and interdisciplinary thinking, making it especially valuable for students interested in mathematics, computer science, engineering, artificial intelligence, and other STEM-related disciplines.

Participation in Ritangle demonstrates strong interest and engagement in advanced mathematical and computational problem-solving. For students planning to apply to competitive STEM programs, especially mathematics, computer science, engineering, data science, and artificial intelligence related majors, Ritangle can serve as evidence of intellectual curiosity, analytical ability, and willingness to participate in internationally recognized academic enrichment activities.
