Hundred Dots Puzzle

The aim is to turn all the 100 dots blue. This includes the control buttons. Simply click or tap on various of the six numbered control buttons.

History This puzzle was coded by Colin Demaine in Skรถvde, Sweden and published on CodePen in 2019. He did not give the solution but did say that things happen even if you don’t do anything and that nothing is random. He hid button number 6 in plain sight and also had the dots spinning faster. My version is gentler on your eyes so I hope you enjoy it.

Hint You need to check what each button does (including number 6, the centre button). Then you need patience to decide when to press them. If you have spent a while pressing buttons and give up here is the devious but simple answer.

Reload the page to restart the dots and then wait patiently for 64 seconds
until rings number 1, 3 and 5 turn blue. Then click/tap button 3.
Wait 6 more seconds until 2 and 4 turn blue and then press button 4.
Finally press the centre button 6.
