One Arrow in This Grid Is Pointing the Wrong Way. Can You Find It?

Here is the whole idea: every arrow in the grid below is identical, except one, which has been turned. Nothing else has been changed — not the size, not the colour, not the spacing.

That sounds easy, and for the first fifteen seconds it is. Then your eye starts sliding over the pattern rather than reading it, which is exactly what makes this kind of puzzle work.

A tip that actually helps

Scanning randomly is the slowest method. Most people do it anyway.

The quicker approach is to give yourself a system: work along one row at a time, left to right, and let your eye travel at a steady pace rather than jumping. Repetition makes the brain very efficient at ignoring things, and a system forces it to keep looking.

If that is not working, try the opposite: defocus slightly and look at the grid as a whole. A rotated shape breaks the overall texture of the pattern, and sometimes the odd one appears as a small disturbance rather than as a shape.

Where this one sits

This grid is set at medium difficulty, which means a moderate number of cells and a turn large enough to see once you are looking in the right place. The harder versions on this site use bigger grids and much smaller changes — a few degrees of rotation, or a single missing line.

Every puzzle here is built from data first and drawn second, so the answer is known before the image exists. A validator checks that exactly one cell in the grid differs from the rest before it is allowed to publish. If two cells differed, or none did, the build would fail rather than quietly go out.

Have a proper go before you open the reveal. The answer below gives the exact square, along with what was changed.
