One way to understand the rules
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Your next round may have a different position, so inspect it before acting. Consider the next action carefully.
Pay attention to this rule
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
