Flash

In bouldering, a "flash" occurs when a climber successfully completes a problem on their first attempt without any prior practice or inspection. This means that the climber hasn't tried the problem before and didn't fall or need to retry any moves. Flashing a problem highlights the climber's skill, intuition, and ability to read the route quickly and effectively.

Examples

When Alex attempted the new boulder problem, she read the sequence, memorized the holds, and succeeded on her first try. This is called a flash. Another example is when Jamie meticulously studied a V5 route, visualized every move, and climbed it perfectly without any prior mistakes—another perfect flash.
