Everyone knows the Doppler effect, a charged, winding maze track, we hold a ring on this line, and then walk the line along the track, with the goal not to touch the track. I guess everyone has suddenly realized after the players said this. Now the mobile game "Doppler" produced based on this gameplay has been launched on both platforms. So, don't run for science students! Come and challenge it quickly!

In this game, the player controls two electrons with two fingers and shuttles upwards on a random twisting and curved waveform. The two electrons cannot be too far apart, nor can they touch the waveform itself. As the game grows, the degree of twisting of the waveform will intensify and the changes will become faster and faster. When can everyone persist? Come and challenge yourself!
