Solitaire Universe is a free Android game developed by Doofah Software. This game is based on the classic game of Peg Solitaire. The objective of the game is to end up with only one peg remaining on the board by tapping and sliding one peg over another into an empty space, and the peg that was 'jumped' over is removed from the board.

This game offers 12 different peg layouts to choose from, and two modes of play: Easy mode, which allows diagonal moves, and Normal mode, which only allows horizontal and vertical moves. Additionally, Solitaire Universe has a multi-level undo system, which allows players to undo moves back to the start of each game. The game also tracks separate win/loss statistics for each board layout for both Easy and Normal modes.

Overall, Solitaire Universe is a fun and challenging game that offers multiple levels of difficulty and different board layouts to keep players engaged.
