THE FIELD NOTES
How to play Rule Switch
- Read the highlighted rule on each question. It tells you which part of the display to use and which competing detail to ignore.
- Choose the answer that follows that rule. The arrow, written word, number or size may suggest different responses.
- Pause and read again when the next question arrives. The rule can change, even when the display looks familiar.
A worked example
If an arrow points up while the word says DOWN, a “follow the arrow” instruction means Up. Under a “follow the written direction” instruction, the same display would mean Down.
A strategy to try
Say the active rule to yourself before choosing. A fast answer to the previous rule is still a wrong answer to the new one.
Choose your challenge
Starter is a good introduction to conflicting cues. More demanding levels add challenge, while untimed play gives you room to check the instruction.
Each round has ten questions. Choose a 90-second sprint or untimed practice. Correct answers earn 100 points; finishing a sprint adds up to 99 time-bonus points. A score describes this round, not intelligence or a medical assessment.
