Use these moments to confirm that your board still matches before continuing.
| Time | What to confirm |
|---|---|
| 0:00 | The opening layout includes countdown blocks labeled 5, 10, 15, and 9, with the cyan 9 block sitting near the lower-left exit lane. |
| 0:20 | By 20 seconds, the cyan lower-left countdown has dropped to 8 while the orange and yellow countdowns are still present, so the lower-left lane cannot be ignored. |
| 1:00 | Around 60 seconds, much of the central board has opened, but blue, orange, yellow, and red pieces still control the remaining exits. |
| 2:24 | Near the end of the clear, the board is almost empty and the remaining visible blocker is the long purple piece on the left side. |
