How to Solve Brain Out Level 21 — Full Solution

Read the phrase there now carefully and treat it as a total-after-deposit question.
Ignore the tempting answer of 3, which only counts the loose coins on the floor.
Enter 15 in the answer field.
Tap OK to submit the total.

When a question says now, it usually wants the final state after the scene change, not the starting number of loose items.

Board notes 5 details

Layout: Level 21 shows a piggy bank, three loose coins, and an answer field underneath the prompt.
Goal: The board is asking for the total after the three new coins are added to what is already inside the piggy bank.
Opening: The video does not stop at 3. It uses the piggy bank state to determine the new total and submits 15.
Danger Zone: The trap is answering with only the number of loose coins you can see on the floor.
Mechanics: This is a total-state puzzle. The prompt says there now, which means you must include the bank's existing contents.
