Four or More is a puzzle game where you must match four or more diamonds of the same color in a row, either horizontally, vertically, or diagonally. The rainbow diamond is a wild card and matches any other color.
Diamonds are initially placed on the screen randomly. More are added after each move not resulting in a match.
The game has 8 difficulty settings, which control how many additional diamonds are placed after each move. The top 10 high scores are recorded, so you can track your play.
