A nice puzzle-game collection. Puzzles have difficulty settings from easy to insane. The interfaces are simple/straightforward, can be used with mouse or keyboard only, and all games adapt to window size changes---enlarge the window and the game board enlarges. Nice!.
Includes clones of Sudoku, KenKen, Minesweeper, and Mastermind, as well as 27 other puzzle games, many quite addictive, with an impressive puzzle generator for unlimited play.
A simple set of puzzle games. You might have to read the manual on how to play each one, but they're simple to figure out after knowing your goal. Good for a lighter set of games on a computer.
The first games I install on every OS. Mind-exercising puzzles that can't be beat.
