A colour word appears, written in the wrong ink. Two taps per card:

Tap 1 · The INK. Tap the button matching the colour you SEE. (The word BLUE written in red? Tap red.) If that button shows a 🔒 lock, or is not there, tap WAIT instead. Never tap a locked button.

Tap 2 · The WORD. Now tap the colour the word SAYS. That brings up the next card.

The last card says FINISH: tap the green FINISH button and you are done.
