Sekigae-kun: Seating Chart

Sekigae-kun is an app that automatically generates fair seating arrangements by considering multiple constraints — so everyone is happy with the result.

"I want to keep those two apart." "This student needs to sit near the front." "I want to separate boys' and girls' seats." — Sekigae-kun solves all of these concerns at once.

【Combine Multiple Constraints Freely】

The biggest strength of Sekigae-kun is the ability to set multiple constraints simultaneously.

- Gender-based seat assignment (paint boy/girl seats on the layout)
- Quick setup with checkerboard, column-alternating, or row-alternating templates
- Restrict specific students to designated areas
- Ensure minimum distance between two students
- Keep specific pairs of students close together (Distance Proximity)
- Arrange students in student number order (freely set starting position & direction) [NEW]
- Place students in different seats from last time
- Set priority (High / Medium / Low) for each constraint

Combine these freely to automatically generate the optimal seating arrangement tailored to your class.
