## Linear vs Circular Seating Arrangement Puzzles

Linear and circular seating puzzles look similar on the surface — place N people according to clues — but the solving strategies differ significantly. Knowing which exam tests which type, and how to shift your approach, saves 30-60 seconds per puzzle.

### Key Differences

| Aspect | Linear Row | Circular |
| --- | --- | --- |
| Position reference | Fixed: seat 1 is far-left, seat N is far-right | Relative: no absolute positions, clockwise from anchor |
| Ends/direction | Has clear endpoints (leftmost, rightmost) | No endpoints — everyone has exactly 2 neighbours |
| "Opposite" clue | Does not apply (no opposite in a row) | Key clue type — person exactly halfway around |
| Facing direction | Usually all face the same way (north/south) | Centre-facing (default) or mixed (some inward, some outward) |
| Typical N | 5-7 people (prelims), 8-10 (mains) | 6-8 people (prelims), 8-12 (mains) |

### Exam-Wise Breakdown

| Exam | Linear | Circular | Double-Row |
| --- | --- | --- | --- |
| IBPS PO Prelims | ✓ 1-2 sets | ✓ 1 set | Rare |
| IBPS PO Mains | ✓ | ✓ | ✓ 1 set |
| SBI PO Prelims | ✓ 1 set | ✓ 1 set | Occasional |
| SBI Clerk Prelims | ✓ 1 set | ✓ 1 set | Rare |
| SSC CGL | ✓ 1 set | ✓ 1 set | Rare |

### How to Approach Each Type

#### Linear Row Strategy

- Lock the ends immediately — any "far-left/far-right" clue fixes a seat.
- Convert "immediately to the left/right" into adjacent pairs.
- Handle gap clues ("exactly k between") by trying each valid position.

#### Circular Strategy

- Pick any person as your anchor — place them at the top of your drawn circle.
- "Immediately to the left" = clockwise-adjacent (facing centre). "Opposite" = halfway around.
- Work outward from the anchor in both clockwise and anti-clockwise directions.
- If the circle has mixed facing directions, mark each person's facing arrow before placing.
