How to play Stroop Rush

1 min read

The task

A colour word appears in the middle of the screen — but it is printed in a different colour. The word BLUE might be printed in red ink.

Tap the colour it is printed in. Ignore the word.

In that example the answer is Red.

Why it is hard

Reading is automatic. By the time you have decided not to read the word, you have already read it. The interference between the word you read and the colour you see is called the Stroop effect, and overriding it is the entire exercise. It gets easier with practice, which is what the score is measuring.

The screen

Element What it shows
TIME Counts down. When it hits zero the run ends.
SCORE Your points so far.
STREAK Your current multiplier. Rises with each correct answer in a row.
The four keys The colours you can choose from.

A wrong answer resets your streak to ×1 and the board shakes. A correct answer bumps the multiplier, so a long clean run is worth far more than the same number of correct answers scattered between mistakes.

Difficulties

  • Chill — the longest run, the gentlest pace. Good for learning the override.
  • Classic — the standard run.
  • Blitz — the shortest and fastest. Built for a personal best attempt.

Each difficulty keeps its own personal best.

Playing without colour vision

Every answer key carries a fill pattern as well as a colour — solid, diagonal stripes, dots, or concentric rings — and the stimulus word repeats its own pattern in ink. Match the pattern and you never have to discriminate a colour.

There is also a colour-blind friendly palette in Settings, which swaps red for pink and green for orange. It changes which colours the round is generated from, not just how they look.

With VoiceOver

The stimulus is announced as the word and the ink it is printed in — "BLUE, printed in red" — and each key is labelled with its colour name. The game is playable end to end without sight of the screen.
