The
rules are simple: the squares of one color
placed side by side form a block (one square
is not a block). When you move the mouse over
the board, blocks are highlighted. If you
click on a block, it vanishes, and the squares
above it shift down (and left if an empty
column is created). The more squares in the
block, the more points you get - the number
is shown on the right of the board. The game
is very strategic in nature - if you think
a few moves ahead, you can assemble larger
blocks that gain you much more points.
