The software offers a set of logical games: Free Renju, Bulls and Cows, and Hanoi Tower. Players can enjoy these games which include different challenges such as moving bricks or guessing numbers.

First up is Free Renju, a variation of the popular Japanese board game known as Renju-Gomoku. Free Renju boasts four different levels of complexity, ensuring that players of all skill levels will find it engaging. Furthermore, the game offers the ability to print out positions and moves, as well as the option to save positions to a file for future play. Customized colors of stones let players personalize the look of the game. A demo game is provided to help players get started.
Next, we have Bulls and Cows. This game tests your ability to guess a number in the fewest attempts and quickest time possible. It's a great game for those looking to exercise their deductive reasoning skills.
Last but not least, the Hanoi Tower game challenges players to move bricks from one position to another in the least amount of time and with the fewest moves possible. Again, a demo game is included to give players a taste of what to expect.
Overall, this software package is great for those who enjoy logic puzzles and want to expand their skill set. Each game is distinct and offers a different type of challenge, making for a well-rounded selection of options.
