If you like really complex puzzles, then the online game Block Hexa Merge 2048 will be a great choice. Here you will see a field with empty cells and hexagons with even numbers. You need to make four hexagons with the same numbers together so that they form one block with the sum of all these numbers. Each empty motion that does not merge results in additional hexagons on the field. Have time to get the number 2048 before all the cells are full.
