20 minutes. Up to 5 questions.
Same format as the real motionChallenge test (6 min). Slide the blocks aside and move the ball to the exit in as few moves as you can. You can go back to earlier questions until the timer runs out.
- • Work backwards from the exit
- • Look two moves ahead before you slide anything
- • A block placed wrong now costs you three moves later
- • Every question is explained afterwards, right or wrong.
