About Parity

Parity is a turn-based arcade puzzler. Your aim is to make large groups of
matching pieces. The larger the groups of pieces you match, the greater your
score. There is no time pressure in Parity. There is an element of luck that
can be overcome by skillful play.

You may select a single group of pieces at a time. The score you receive for
each selection is based on the number of pieces that you manage to bring
together in a group. Larger groups earn many more points. A group is a number
of similar pieces connected by the horizontal and vertical edges. Lone pieces
not in a group cannot be matched or selected. The number of remaining pieces
at the end affects your score; the fewer, the better.

As you make matches, the pieces will fall from the board. The remaining pieces
will move together and the puzzle will continue. On the basic levels, all
pieces fall downwards, and if any columns are freed then the right of the
board will be shifted leftwards to close the gap.

To get huge scores you will have to make matches with very large numbers of
pieces and clear the board entirely. Remember that you cannot match lone
pieces, so you must ensure they all end up in groups or you will throw
precious points away.

The is no time pressure in Parity, but a fair degree of luck that can be
overcome with skillful play. You can get up and walk away at any time without
affecting the gameplay.
