04 Try it yourself Interactive

Read the statement, watch the tools fall away

Press Next to reveal one clue at a time. The highlighted line is the phrase being read, the chips are the six tools, and a chip turns rose the moment the clue rules it out — with the reason written on it. Then switch to Problem B and watch the same four questions land somewhere completely different. Nothing moves until you press a button.

Problem A
6 tools live
Two different statements, the same four questions. Use Back to re-read a clue, or the left and right arrow keys.

      

      
Press Next to begin. Each press reveals one clue.
