This is yet another implementation of the 2048 game, implemented in Ada using ASFML for graphics and ada-toml for saving state.

It has been tested under Windows 10 and Ubuntu Linux 20.04.

Features

• Different themes can be switched while playing. Five themes are included, but the user can add up to nine themes, following the same structure.
• Best score and best time
• Fullscreen
• Saving of the state
• Undo last move
• Three board sizes:
  • Small (3x3): difficult, beat your score!
  • Default (4x4): normal, you can do it!
  • Easy (5x5): easy, beat your best time!

How to build

• Install Alire
• Build using alr build. All the dependencies are installed and managed by Alire.
• Run using alr run (mandatory in Windows so it finds installed libraries) or directly from the working directory: ./play_2048 (Linux only).

How to install

The game can be installed using Alire 2.0 with this command:

alr install

Refer to Alire documentation on how to add the Alire default installation to the PATH variable or how to change the default installation prefix.

If Alire 2.0 is not available, you can still install the application using something like this:

sudo make PREFIX=/opt/play_2048 install

If you're interested in building the AppImage file:

make AppImage

How to play

Use arrow keys to move tiles. When two adjacent tiles with the same number are merged, their numbers add up. Keep merging tiles until you get to 2048. If the board is full and there is no possible move (no adjacent tiles with the same number), you lose.

To change the board size, export the enviroment variable PLAY_2048_SIZE to the number of cells per size, for example, in Linux/Bash:

export PLAY_2048_SIZE=3

After a change in the board size, the board state will not be restored.

Keys:

• R - restart game
• Q - quit game
• Arrow keys - move tiles
• U - undo last move
• F11 - toggle fullscreen mode
• Tab - switch theme

Attribution

The initial implementation of the game logic was taken from Rosetta Code, although it has been mostly rewritten.
