Turbo Blocks

Simple puzzle for everyone. Drop from one to three blocks into the board to group them by colour. Groups of three or more blocks (not necessarily in one line - L-shaped groups are counted too) of the same colour are removed from the field. Game objective - remove all blocks from the central field.

A block can only be dropped to the field if it can collide with another block.

After the collision the block retains its momentum, so it continues to slide further when the obstacle is removed. If there are no more obstacles on its way then the block leaves the central field. When multiple blocks are sliding the oldest block on the field moves first.
