Numbers chain reaction

The rules of this game are super simple. You have 5 lives (represented by hearts) and you can click on any box with a number. When you click on a square, you lose a life but you add +1 to the number in that square. If at least 3 boxes with an identical number are next to each other, then they join together to form a higher number. This new higher number can also now form a new group of 3 or more and so on ... That's it, you understand, but will you be able to generate chain reactions?
As long as you have lives the game goes on, but when you lose your last heart ... it's over.
You have 2 game modes at your disposal:
- Endless mode: try to get the best score is your ultimate goal
- levels: 40 levels from easy to most difficult. A real challenge awaits you to finish them all.
