Cblocks puzzle for PC

In this game, you should place falling blocks to organize them into 'closed' groups (see below).
While the block is falling, it can be dragged left or right. You can also speed up the block's fall by swiping down or by pressing corresponding button.
As your score increases, so does the falling speed of the blocks.
Once the block reaches the bottom or another block, it cannot be moved anymore and the next block appears. You can see the next 3 blocks on the right side of the screen.
The game is finished once there is no more space for new blocks to appear.
Each block has 0-4 connectors. If two neighboring blocks have connectors attached to a border, they are considered 'connected' and belong to the same group. Blocks that belong to a group share the same color.
Group considered 'closed' if it has no 'loose' connectors i.e. for every block in this group all its connectors either connected to another block in the group, or connected to a field border.
Once a closed group is created, all its blocks disappear and you are getting a score equal to the square of the number of disappeared blocks. All blocks on top of the group (if any) fall down.
A block with no connectors is special. It removes the block it falls onto (or simply disappears if it reaches the bottom).
