FEAST I style, test 4 of 15
Visual scanning
Data blocks drift across the screen. Quickly find the ones whose value is outside the allowed range.
- Each block has an ID at the top (one letter and two digits) and a three-digit value below it.
- The current range is shown at the top, for example 360–710. Values can change while the blocks are moving.
- When a value is outside the range, click the block or type the two digits of its ID and press Enter.
- Your score depends on how many you find, how fast you are and how few wrong clicks you make. The range changes halfway through.
