Layout
- Seven more targets than 3×3
- Four rows remain easy to scan without the density of larger grids

What is specific to 4×4
A compact 16-target bridge between the very short 3×3 demonstration and the site's standard 5×5 timed task.
Small-screen behavior
- Often retains comfortable cell width in portrait orientation
- A useful size for checking whether page zoom produces readable labels
Mouse and touch
- Longer than 3×3 but still compact enough to learn how the cursor remains at the previous target
- Provides room to become familiar with the gentle wrong-target response before choosing denser layouts
Readability
- Introduces two-digit targets through 16 without crowding a typical viewport
Printing
- Can be placed several times on one page while keeping labels readable at ordinary print scales
How to compare this size
- Keep 4×4 results separate from both 3×3 and 5×5
- A longer sequence is a task change, not a promotion in ability
Choosing a neighboring size
Return to 3×3 when you want to demonstrate the controls with the fewest targets.
Use 5×5 when you want the same 25-target condition used by the site's fixed speed test.
Your comparison context
These values come only from completed ascending rounds stored in this browser for this exact grid. Choose an input method to narrow the set.
No comparable attempts are stored yet. Complete several rounds with the same grid, device, input method, and rules before interpreting changes in your own history.
Device model, orientation, browser zoom, and display scale are not stored. Confirm those conditions yourself before treating two rows as like-for-like.
