Double Play resembles the 15
Puzzle, with square tiles numbered 1 through 12
contained in a 4 x 4 frame along with four empty cells.
It has just one new rule: The tiles can only slide in
pairs, with one tile pushing another.
The object is to move the tiles from any given or random
position (pattern) back to the Home pattern, which is a
cross-like square shape with empty corners, with the
numbers arranged in ascending order from top to bottom
and left to right as shown in the diagram on the left.
Move pieces clicking them.
Choose a challenge from the Patterns menu.
You can shuffle (randomize) any chosen or current
position at any time, and then solve the puzzle from
that position. Use the Puzzle menu to start/finish
Shuffling (or tap keys S and F, respectively). To start
the puzzle over again, choose the Restart option in the
Puzzle menu (or tap key R).
To undo/redo your moves, use the respective option in
the Moves menu (or tap keys B and N, respectively). In
the Moves menu you can make the Move Counter on or off.
Bear in mind that all of the Double Play challenges are
quite difficult. Happy Puzzling!
