13-year-old South Korean Prodigy Releases First Game After Oxford Rejection

'Blind Tank' is a strategy puzzle game where players cannot see the enemy. They have to guess where the enemy is by looking at messages after each shot. The game is turn-based, and players have to think ahead to win.
The boy, Baek, said his game tests logic, memory, and how well players can handle pressure. He made the game by himself, and it is as good as games made by big companies. An iPhone version is also coming soon.
Baek is very smart and was on a TV show when he was 41 months old, solving math problems.
Baek was on a TV show in 2016, solving hard math problems and showing his talent in music. His IQ is very high, putting him in the top 0.0001% of people in the world.
In 2023, Baek went to a special school for smart kids, but he left after one semester. He wanted to focus on his own projects, and his father said he was bullied at school.
Baek wanted to go to Oxford University and posted his high test scores on YouTube. He took a special test, but the university said no to his application.
Baek took the test in October 2025, and 396 people were chosen for an interview. Only 163 people got in, and Baek was not one of them. He was sad, but he learned a lot from the experience.
Baek was very sad when he did not get into Oxford, but he will not give up. He thinks the experience was helpful and taught him a lot.
Baek will be on a TV show this month, the same show that made him famous when he was younger.
