Watch it in action
🪟 How it works
- A Panel protects 9 unknown boxes behind a closed door; the number tells you how many bottom boxes you still need to complete before it opens.
- Every completed bottom box lowers the number by 1 regardless of color, and at 0 the panel opens to reveal the 9 boxes.
- It blocks information, space, and future options at once; behind it may be normal boxes, Hidden Boxes, or mixed ones.
- Unlike a normal blocker ("clear this, then continue"), a Panel makes you survive a while with fewer options first.
Pro tip
Treat the Panel as a timer: clear easy bottom boxes first (any needing just 1-2 marbles), which lowers the number and frees space fast. Slow down near zero and stop panic tapping. Hold one almost-finished bottom box, then finish it to open the panel exactly when the belt is about to get messy, so the new 9 boxes appear when you most need extra destinations.
