Train your mind, one game at a time.

A plate flashes for a blink, then the screen goes blank. Don't read it as it goes by: let it land, then rebuild it. Pick Easy to Harder, or Climb as the flash gets shorter.

Iconic memory: Sperling's partial report

Build the goal in the fewest moves. No clock, just how far ahead you can see. Climb an adaptive run, pick Easy to Harder, or switch on Hanoi rules.

Planning: Tower of London and Hanoi

A little twist. A lot of flow. Turn the tracks to connect the ends. Choose your difficulty, or level up in a 45-second Sprint.

Spatial logic, four difficulties, adaptive Sprint

1, A, 2, B… Keep the rhythm. Tap numbers and letters in alternating order as fast as you can.

Task switching and attention

Same shape, just turned, or its mirror image? Spin it in your head and answer fast. Every answer shows you why.

Mental rotation, adaptive shapes

RED, printed in blue? Tap blue. Beat your reading reflex and name the ink, not the word. Then the rule starts to flip.

Focus and impulse control

Connect the numbered dots in order until the path fills every square of the grid.

Logic and path finding

Spot when the square lands where it was N steps ago. A classic working-memory exercise.

Working memory

Drag through the digits to hit the target sum before the clock runs out.

Mental math

A few dots glow, then vanish into the crowd and scatter. Keep your eyes on them and pick them out when the swarm stops. Every perfect round makes it harder.

Divided attention, adaptive tracking
