Green Flag to start. (Turbo Mode recommended, SHIFT+FLAG) NEXT to continue instructions Click Penguin to play. Select a puzzle size. Recommend size 3 to start. (Puzzles may have more than one solution.) A domino consists of two numbers. To place a domino, click between two numbers. You solve the puzzle by placing all the dominoes exactly once each.. When you place a domino, it shows in the 'placed' list. To remove a domino click it again. A bar will remain to mark that spot. To remove the bar, click it. To remove all the bars, click the 'Clear Bars' button. The 'Dupes' list warns you to remove one of the dominoes listed there. To clear all selections and restart the same puzzle, click the 'Clear All" button. While in a game, click the (S)ave button to create a save point. You can make a save point again if you wish, but you can only (R)estore the most recent save point. It takes some time to discover the various strategies available. Enjoy the process! Note: It should take less than 10 seconds for Pierre (the penguin) to think up a puzzle. Sometimes he may have to "try again". Please, be patient with him.
