Count the Rectangles
Count the Rectangles (네모 세기) — count the rectangles whose sum hits the target number. Buzz in, 10 seconds, two correct answers to win.
- A grid of digits and blank squares appears with a TARGET NUMBER. Count the grid-aligned rectangles (any size, 1×1 included) whose digits add up exactly to the target.
- “N OR MORE” rounds: the sum must be greater than or equal to N. Target 0: rectangles made only of blank squares — a blank a×b block contains a(a+1)/2 × b(b+1)/2 rectangles.
- Press the BUZZER, then give your answer within 10 seconds. Wrong answer: your team is locked out of that problem. 5 minutes max per problem.
- The first team to score two correct answers wins and leaves the game. The game ends once 5 of the 10 teams have won.
- Winning trio: 7 points to split • losing trio: up to −4 • winning individual: +7 • losing individual: −3.
- Tip: drag across the grid to trace and pin a rectangle so you never count one twice.
In the show: Jang Dong-min played solo and won in just two rounds (6, then 114 on a target-0 grid thanks to his blank-block formula). Team Rectangle (Kim Dong-jae, Oh Hyun-min, Jung Won-young) won and chose SACRIFICE; Hyun Kyung-lyul, XITSUH and Jung Hyun-gyu completed the 5 winners (4 of them solo). In the Challenge, Jang Dong-min beat Jung Hyun-gyu (27) and earned 3 Pieces.
Logic & DeductionCount the Rectangles
The mini-game where Jang Dong-min chose to play alone against everyone. A grid of squares (numbered or blank) and a target number appear: find how many rectangles add up to the target (or “5 or more”). Play in a trio or solo, buzz in, answer within 10 seconds. The first team to two correct answers wins. Then live Selection 3: Monopolize or Sacrifice, Challenge or Safety.
