Slide the COLOR tiles (in the WHAT, WHERE and WHEN columns) to make a correct statement in the FIRST row. Then, do the same in the second row. Only one row is 'active' at any time, and the active row is indicated by a grey rectangular border. The first row must be completed correctly before the second row becomes active.
Hint: If you know the answer to the second or third row, you can move those tiles into place first, and it will narrow down the possible tile combinations for the first row.
