How to play

A hidden code sits at the top. Pick shapes below (each has its own color and a Chinese numeral from 一 to 八), tap Check and read the feedback. Tap a piece in the active row to remove it. On a keyboard, keys 1-8 pick the shapes in order, then Backspace and Enter.

  • Right piece in the right place
  • Right piece, wrong place

Feedback doesn't say which piece it refers to.
