How to play

  1. 1Put on training glasses; the screen has many random dots.
  2. 2After binocular fusion, a letter E rises up.
  3. 3Judge which way E opens: click directional buttons on the sides, swipe in that direction on blank area, or press arrow keys.

Tip

Stare at the centre cross and sense the raised E with your side vision. If you really can't see it, tap "Can't see the E (skip)" — don't guess.
