The word and the ink usually disagree. Sometimes you answer about the ink, sometimes about the word. Read the instruction each time — that is the hard part.
RED
60 seconds · wrong answers cost 1.5s
A colour word appears, printed in a colour that usually is not the one it names. Above it is the instruction: sometimes “tap the colour of the word”, sometimes “tap what the word says”. It swaps between the two at random, so you cannot get into a rhythm and stop reading.
This is the Stroop effect: your brain reads the word faster than it registers the ink, so the two answers compete and you have to actively override one. A wrong answer costs 1.5 seconds off the clock rather than ending the run, so one slip is survivable.

When the word "RED" is printed in blue ink, your brain reads the word faster than it sees the colour, and the two answers fight. That interference is the Stroop effect, and this game is built on it.
Read the instruction at the top — sometimes it asks for the colour of the ink, sometimes for what the word says. It swaps between the two, so you cannot settle into a rhythm. Sixty seconds, as many as you can.
You lose a second and a half off the clock rather than the run. It costs you, but a single slip does not end a sixty second game.
Partly. The game is colour-dependent by nature, but every answer button is labelled with the colour name as well as the swatch, so the choices are always readable as text.
