The tests

Four tests, each with practice and a test mode

Dice Roll

Two lettered dice: could the right one be the left one rolled? One rule settles every pair, and the guide teaches it.

Polygon Rotation

Turned or mirrored? Practise spotting the difference quickly on shapes that get harder as edges grow.

Shortest Path

Find the shortest route past closed streets and type the building it passes. Practice draws the route in green.

3D Balancing

Tip a spinning shape until it stands straight out of a leaning base. Practice shows the axes and how many degrees off you are as you move it; under 1° counts as right.

How it works

Practise, then test yourself

  1. Sign in with Google or Microsoft. No new password to remember.
  2. Practise without a clock. After a wrong answer you see the right one, with a tip explaining it on full access, and it waits until you are ready.
  3. Take timed tests of 3, 5 or 10 minutes (3D Balancing: 25 examples, no timer). Your score, speed and the kinds of examples you struggle with are shown after each one.
  4. Get your report by e-mail. With full access, a PDF of everything you did, after any test and when you sign out.
