3-4 Set has more than 30 different game settings with many more different layouts and hundreds of appearances since there are dozens of images used for the game. It will take time to master all variations of the game. The gear icon opens the settings screen.

The game can be played as 3 set, which is somewhat more difficult than tic tack toe, as 4 set for a more difficult challenge or Random for the ultimate game. The board contains 3 or 4 sets of game pieces depending on the game setting choice. In a standard game the first set contains 1 item, the second set contains 3 items, the third set contains 5 items and if there is a 4th set it contains 7 items. The game can also be played with a Random number of game pieces for each set (3, 5, or 7 pieces in a set). Players alternate turns. A player can also play against the computer.

The player who forces his/her opponent to select the last item on the board is the winner. HAL9000 is the name used to play against the computer. HAL is a challenger that does not think they can be beat. HAL can ungraciously lose, however playing against HAL certainly will hone your logic skills for playing others.

This game provides opportunities for exploring and learning winning strategies. Game patterns will become apparent after playing the game many times. Challenge yourself by learning patterns to improve winning chances against your opponents or HAL. It will be easy to discover a pattern for winning the standard 3 set game. It will be much harder for random 3 set or standard 4 set or random 4 set games. A hint is 1, 1, 1 (0) is a winning combination. That is if you leave only one piece in 3 of the piles and 0 in the fourth if playing a 4 set game, then you will win!
