How scoring works
Correct detection and continued progression build the result; consistency across harder rounds matters more than one lucky click.

The useful way to improve is to understand what the game is measuring. In Signal, the important pressure comes from Later rounds increase perceptual load and make the target less immediately obvious, testing search strategy and concentration. That means repeat runs are not only attempts at a better number: they are opportunities to recognize the decisions that create that number. Use the strategy above as a starting point, then compare your own runs and identify where time, accuracy, moves or survival are being lost.
Small Games keeps the rules visible because a leaderboard is only useful when players understand what is being compared. Read how scoring and verified results work, browse the complete Game Guides, or learn how Small Games is designed.
