A fun brain game! Play it casually on easy level or challenge your brain on the harder levels.

In each game a complete set of domino tiles are randomly placed on the play grid. Since each tile pair only occurs once in the grid (1-1, 1-2, 1-3, 1-4, 1-5 … etc) after a certain tile has been placed other locations with that number pair can no longer contain a tile.

Slide your finger over a pair of numbers to add a new domino tile to the board.

Once all of the domino tiles are placed with no duplicates you win!

Every game is randomly generated so you will never run out of new games to play!

To help check which tiles remain, there is a domino statistics rollup that shows which dominoes have already been used. Dominoes that have been placed on the board once are shown with an X. If more than one domino number pair is placed, a star will appear in the grid easily showing which tiles are incorrect.

The idea is simple, but the grid play can be surprisingly complex. Try out a few easy games to get the hang of how to play and you will be ready for a more difficult challenge on a larger play grid.

There are nine different tile sets to choose from and three grid sizes.
Also your play statistics will be saved so you can see how many times you have played each board size and your four fastest times.

Options:
On the options page you can choose one of the three grid sizes (5x6, 7x8 and 9x10), the difficulty level (easy, medium or hard) and the tile set. choose one of the sixteen grid skins. The options will be saved so that the next time you play your favorite grid size and skin is automatically enabled.

View Mode:
When changing the view style (landscape/portrait), the numbers will automatically update so that the grid can easily be viewed from any of the four viewpoints. Only the numbers change (not the domino tiles) so this allows you to view the puzzle from different angles which might be helpful seeing possible solutions.
