How to unlock the Chain reaction achievement in Fishdom 3: Special Edition - Definitive Guide
There is 13 mines and fireworks in a row so you will get it no problem.
I am playing this game on a surface, so this may not be possible with a mouse and keyboard.
To unlock this achievement, you have to set off an explosive that also triggers at least two more explosives. Keep in mind that unlike other similar games, you don't actually need to switch explosives to set them off. You can tap on them twice to make them explode in place. This is handy in many situations.
You could attempt to create three explosives close to each other, but it's easier to let this happen naturally. There are many levels in the game that essentially require you to make explosives to progress, and the levels are set up to allow you to create explosives right from the start. When you get to one of these levels where you make two explosives right from the start, just make a mine or other explosive between them so they're close enough to set each other off.
