Unlike Classical Puzzle Games such as 2048 or Dominoes Puzzle, here you have to build your game strategy properly so that you get the highest score amongst the competition.
You will have access to coins and you can use these coins to apply the Hammer and destroy some blocks or apply the Double Rainbow to get a piece that will combine with any dot.
You will get more coins by playing the game frequently, but you may also buy some coins or watch a video to get some.
As you match 3 or more pieces, you will be loading the Combo Breaker. When it is fully loaded, you can use it and it will upgrade 2 of your blocks, randomly.
So, what are you waiting for? Start merging & matching & connecting them all!
