Mindbuster

Mindbuster is a puzzle game with an ultimate goal to complete puzzles in
the fewest moves possible. There are two separate individual games in
Mindbuster :

The first game is called Rings. In this, players must place circles around
points on the screen. The second game is called Lights Out and is similar to
the titles Tiger Game.com game of the same name. In it, there are a series of
squares onscreen representing lights, and players must put all the lights out.
Depending on the light selected using the numeric keypad, it may activate some
areas while deactivating others.

Both games follow the same basic rules. The gameplay screen is a 3×3 grid, and
each numeric button affects nearby sections. The grid is set up as follows:

1 2 3

4 5 6

7 8 9

Selecting 1 activates spaces 1, 2, 4, and 5, and likewise for the other corner
points. Selecting 2 or 8 also activates the spaces to the left and right of
these points. Selecting 4 or 6 activate the spaces above and below as well.
Selecting 5 activates the most spaces in the shape of a + sign. For example,
if the gameplay screen has spaces 2, 3, and 6 highlighted and the player
selects space 3, spaces 2, 3, and 6 will deactivate but space 5 will activate
and so on. The game is won when all target blocks are surrounded in Rings ,
or when all lights have been deactivated in Lights Out.
