Stop The Timer

An ominous countdown has started and you have 20 seconds!

Click a switch to toggle between ON and OFF

Set the switches and click the red button to try and find the correct  pattern.

For each switch that's right you'll get a green light, for each that's wrong you'll get an unlit light

If you get a pattern completely correct, the Ominous Countdown Machine will give you a new pattern with 1 extra switch

Can you make the countdown stop?  If not, how many patterns can you correctly set in 20 seconds?!
