Look and Remember

A grid of drawings appears for a few seconds, then three questions: how many cats? What was in the top-left corner?

Rules

1. A grid of drawings appears for a few seconds: take a good look.
2. The grid disappears and three questions follow: how many times a drawing appeared, what was in a given spot, and which of four drawings was in the grid.
3. Every right answer scores points, and answering fast scores more.
4. Easy: 3 × 3 grid and 6 seconds to look. Normal: 4 × 4 and 4.5 seconds. Hard: 5 × 5 and 3.5 seconds.
