Difficulty scales dynamically from Level 1 to 25 based on response precision and speed. Correct answers advance difficulty (+1 level); mistakes drop difficulty (-1 level) to measure your cognitive ceiling.
Benchmark accuracy
Complete at least 6 questions in a full timed session with ≥75% accuracy to unlock higher difficulty baselines and persist high-water marks.
Assessment rules and guidelines
- 1A grid contains a 1x1 Red Ball, an immovable Nailed Block, movable rectangular blocks, and a Target Hole.
- 2Blocks slide along their fixed axis (horizontal or vertical) until hitting another block or the wall.
- 3You can move ANY movable block, including the red ball itself.
- 4Slide blocks out of the way and navigate the red ball onto the hole in as few moves as possible.
Strategy and pacing
- Identify which blocks directly obstruct the path between the ball and the hole.
- Clear clearance space behind obstructing blocks before attempting to move them.
