ZACK! is a software that combines puzzle and strategy, and is highly addictive.
The goal of ZACK! is to place colored squares in a grid without getting stuck. To make a move, the color of the square you're placing must match the colors of its neighbors. This means that you need to pay close attention to the colors of the squares already on the board.
To make things more interesting, there are also gray stones that act as jokers. You can place a gray stone in any free slot, regardless of its color. If you manage to fill an entire row or column, it will be removed from the grid, giving you more space to work with.
Overall, ZACK! is a fun and engaging game that will keep you entertained for hours on end. It's easy to learn, but challenging enough to keep you coming back for more. However, it's worth noting that there are only 20 test games available, so you'll need to make every move count!
