Combination box
Advice to keep and open it on the next day, which means, after you have saved.
When open it may contain a boom or nothing. If it is a boom
1.) click on line that NOT connect to the display, and NOT the same color as indicated
2.) click on the line indicated
3.) click on remaining line.
Well it seems no bonus/ achievement when boom diffused.
