Numbers chain reaction

The rules of this game are super simple. Five lives (represented by hearts) are given, and any box with a number can be clicked on.

A life is lost when a square is clicked, but the number in that square is increased by one.

If at least three boxes with identical numbers are next to each other, they will join together to form a higher number.

This new higher number can also form a new group of three or more, and so on.

The game continues as long as lives are available, but when the last heart is lost, the game is over.

The challenge is to generate chain reactions. Take the challenge and play now!
