pymetrics games / Towers
pymetrics Towers practice
Move coloured discs between three towers until they match the target, in as few moves as possible.
One full free game, then a pymetrics pass ($4.99 for 30 days, paid once) for unlimited practice. No official rules are public. We built it from the published research task it is based on and what candidates and other practice sites consistently report.
How Towers works
- The target arrangement is at the top; your towers are below.
- Only the top disc of a tower can move. Tap a tower to lift it, then tap where it goes.
- Match the target to finish the puzzle. You can start over, but your moves still count.
- Practice has eight puzzles that need from 3 to 9 moves.
Time and scoring
About 4 minutes. Moves used against the fewest possible, and how long you plan before the first move. pymetrics does not mark answers right or wrong overall: it builds a profile of traits and compares it with people who do well in the role. How that turns into a decision is not public. Our result shows practice measures only.
Tips
- Plan before touching anything: find which disc has to go to the bottom first.
- Work from the bottom of the target up; a disc in its final place should not need to move again.
- Starting over rarely saves moves; think one step back instead.
Questions
Is it the Tower of Hanoi?
No size rule: any disc can sit on any other. It is closer to the Tower of London task used in psychology.
Is it timed?
Candidates do not report a time limit, but time before the first move is said to be recorded.
