The demonstrated final first-board set is r1c1–r1c3, r2c1–r2c3, and r3c1–r3c2.

Read the replacement tile again. The later visible board places the stop sign on the right, with checks at r1c3–r1c4, r2c2–r2c4, and r3c3–r3c4.

Select the demonstrated stop-sign tiles in the 4×4 grid, re-read refreshed tiles, and use Verify after the later right-side stop-sign set is checked.

If the player asks you to sign in, open the video on YouTube instead.

Read the blue Stop Sign prompt and use row/column coordinates for the 4×4 grid.
On the first board, select r1c1–r1c3, r2c1–r2c3, and r3c1–r3c2.
Watch the selected tiles for refreshes and inspect the replacement image.
On the later right-side board, select r1c3–r1c4, r2c2–r2c4, and r3c3–r3c4 as demonstrated.
Press Verify and wait for the Level 3: Wiggles screen.

Board notes 5 details

Layout: A phone-browser Neal.fun page places the prompt `Select all the squares with a Stop Sign` above a 4×4 image grid. The first board has a red stop sign on the left and a yellow pedestrian sign on the right.
Goal: Check every tile containing any part of a stop sign, including refreshed tiles, then press Verify.
Opening: The first demonstrated checked set is r1c1–r1c3, r2c1–r2c3, and r3c1–r3c2.
Danger Zone: The yellow pedestrian sign is a decoy, and refreshed tiles must be evaluated from their new image rather than an old coordinate.
Mechanics: Dynamic 4×4 image selection with tile refreshes and a blue Verify control.
