Signal Stream is a simple game with two stages. Signals appear from the upper part of the screen and move downward. The goal is to tap each signal before it disappears.
Each captured signal adds one point to the score. Missed signals do not affect the result. Each stage lasts 30 seconds, and the pace increases on the second stage, making the gameplay more dynamic.
To move forward from the first stage, at least 8 signals must be captured. If fewer are collected, the stage can be replayed. The second stage introduces a faster flow of signals and requires more attention.
After completing both stages, the total score is displayed. The game keeps track of recent results, allowing comparison between sessions. The mechanics are simple and focused on timing and precision.
