"Group the moving coloured blocks into rows from left to right, or top to bottom."
Some games that consist of placing balls or blocks by colors have something special about them, because new games in this genre are continuously being launched, as is the case of this Block Shifter.
The objective in Block Shifter is the usual case: you have to get 3 blocks of the same colour together, either horizontally or vertically to remove them. The more blocks you delete in the shortest possible time, the higher the score.
To get to group them by colour, you must move each row from right to left or up and down, but of course, in Block Shifter when you match some, you'll unmatch others, so be careful when making your move.
