Flash Clear spawns obstacles that appear briefly on screen before fading away. Tap each one quickly to clear it and score. Obstacles that disappear on their own count as missed—let too many slip away uncleared and the game ends. The field can fill up fast if you hesitate, turning every second into a race against vanishing targets. Quick taps and sharp scanning are your best tools. Simple one-touch action keeps the pace frantic, while rising spawn pressure tests how long you can keep the screen under control. Clear them all before the backlog ends your run.
