Pulse Duo

Pulse Duo is a fast-paced puzzle game that challenges your sense of size and timing.

Tap the blue circle at the perfect moment to lock in its value. Then judge the orange circle only by its size and tap it. Your goal is to make the total match the target number.

The circles continuously pulse and change size, so every decision requires quick observation and precise timing.
