Tap the row with 3 oranges to fill the top row. Starting with any other row or column will leave at least one empty glass when you’re finished, so the 3 oranges will always be your first move. Tapping the 3 oranges on the right side will fill all the glasses in the top row.^{[1]

- Some filters show apples instead of oranges, but they are still laid out in the same pattern.
It doesn’t matter if you choose the column in the middle or on the right first, as long as you pick them before the single oranges. The 2 oranges will skip over the full glasses in the top row and fill in the bottom 2 glasses in each column.^{[2]

Pick the row and column with a single orange in either order. All that’s left is the left column and the bottom row. Now that all the other glasses are full, you can tap these in either order to fill up those final glasses and solve the puzzle.
- You can technically place the orange in the left column right after filling the top row, but you must fill the remaining column before tapping the bottom row.^{[3]

Look at the visual above: which glass has the most juice? There are 4 glasses of different shapes and sizes, all filled with juice. Can you tell which one contains the most? Challenge yourself by setting a timer for 10-15 seconds and try to answer before it goes off. When you’re ready for the answer, scroll down!
- Need a hint? Here are some helpful things to keep in mind before you answer:
  - Anything else in the glass reduces the amount of juice inside.
  - Liquids take the shape of their container, so a smaller amount of juice in a tall, narrow glass may look like it contains more juice than a wide, shallow glass.^{[4]

Answer: The third glass from the left. The standard glass with the wider top has the most because it has the largest volume. Here’s why:
- The ice in the first glass takes up space, so it can’t hold as much juice. If you took the ice out, the glass would appear much emptier.
- The second glass has a stem and a narrow section, so it doesn’t have as much volume as the other glass.
- The fourth glass is the same height as the third glass, but it’s a lot narrower. The volume of a cylinder depends on the size of the base, and the glass’s smaller base means it holds less juice.
