Anybody who knows pool knows there are a million different ways to play good old 8-ball, with official, non-official, international and bar rules. Much like Solitaire, there are also tons of variation games, some better known than others.
Q-Ball has the 3 main games: Eight Ball, Nine Ball and Rotation. 8- and 9-Ball each have variation games in Vs. Mode, a total of 5 default game modes. 3 additional games can be unlocked by winning in Vs. Mode, and are played as 2-Player, but not against a computer opponent. They are Carrot, Bowlliards and Random Six. Bowlliards is the only 'real-life' game I've come across outside 8- or 9-Ball, and plays like frames of bowling, but with billiard shots. Interesting... All of these games come under Vs. Mode, which is probably the deepest in
Q-Ball for sheer variety. Playing against AI opponents, you choose which of the default games to enter, and then play for winner. If you manage to beat one of the computer players through all 5 default games, you can win a custom cue for play elsewhere. Most cues in the game respond somewhat differently and are weighted toward a certain style of play. Winning against AI opens up options like new games and extended choice of rules and settings. Each opponent has a particular style of play, requiring that you modify your approach accordingly. With 10 computer opponents in all, Vs. Mode will give most folks plenty of play-time.
Outside Vs., Q-Ball has the expected Free Play Mode. This is just you, the night and the felt, playing the game of choice all by your lonesome. Somewhere between Vs. and Free Play is Frozen Game. This ends up being more of a puzzle mode than anything else. In several obstacle courses, balls are set on the table and it's up to you to follow a set of instructions like pocketing a ball and then getting as close as possible to a second ball. You're then rated on how well you performed, and points are tallied at the end for your final score. Frozen Game Mode is all about precision, and it's fun if approached with the right preparation and mindset. See, Q-Ball has a killer training mode, Billiard Lessons. Taught by a pro player, Yoshikazu Kimura, these lessons are actually some of the most challenging parts of the game. Everything from straight shots and power to curving, english and mass are addressed here, and you can't move on until each lesson is complete. A full Glossary of terms is available if things like mass are a mystery to you at first. By the end of all 10 lessons, you'll be jawing at the pool-hall with the best of them, a regular shark.
