The Tesla Coil is a powerful match-3 element that appears alongside Batteries.
You activate the Tesla Coil in two stages. First, collect as many Batteries as the number on it says. You can collect Batteries by making matches around them or using power-ups.
After that, make five matches next to the Tesla Coil or use boosters to fully activate it. Once active, the Tesla Coil sends an electric current to elements and destroys them.
