Why grid size matters
Cell count grows from 9 on a 3×3 table to 100 on a 10×10 table. More targets, a wider layout, and smaller cells can all increase total time.

Use these site-defined ranges only to understand how task length changes with grid size. They are not population averages or performance norms.
| Grid | Cells | Getting familiar | Building consistency | Quick attempt | Personal challenge |
|---|---|---|---|---|---|
| 3×3 | 9 | 15–25s | 8–15s | 4–8s | < 4s |
| 4×4 | 16 | 30–50s | 18–30s | 10–18s | < 10s |
| 5×5 | 25 | 60–90s | 35–60s | 20–35s | < 20s |
| 6×6 | 36 | 90–150s | 55–90s | 30–55s | < 30s |
| 7×7 | 49 | 2–3.5 min | 75–120s | 45–75s | < 45s |
| 8×8 | 64 | 3–5 min | 2–3 min | 60–120s | < 60s |
| 9×9 | 81 | 4–7 min | 2.5–4 min | 1.5–2.5 min | < 1.5 min |
| 10×10 | 100 | 6–10 min | 3.5–6 min | 2–3.5 min | < 2 min |

Keep accuracy visible
A time without its error count is incomplete. If two attempts use different error rules, their totals are not directly comparable.
Frequently asked questions
Where do these ranges come from?
They are site-defined examples for practice orientation. They are not calculated from verified site-user or population data.
Can I compare 5×5 and 6×6 total times?
Not directly. The grids contain different numbers of cells and use different layouts.
What is the most useful comparison?
Compare your recent attempts with the same grid, rules, device, and input method.
