Tetris solver

A tetris solver on top of samtay/tetris. It got me a 10_000_000 score until I was no longer interested in waiting.

Bruteforces (see more: Solve.hs) all two next moves with the scoring function that

• penalizes each occupied block on the screen,
• penalizes each free block with occupied blocks above it,
• weighs each block according to its height in the game (high is bad),
• scores by (scoreAfterTwoMoves, scoreAfterFirstMove), which is important.

UI features on top of samtay's tetris

• Left/right rotation buttons
• Save-game implemented (~/.local/share/tetris/saved.json)
• Has an autosuggest feature (and solve)
• Pause has the board visible behind "Paused"

Installation

Nix

nix build github:siers/tetris/solver

Usage

The default game is run by simply executing the tetris command. If the unicode characters look a bit wonky in your terminal, you can also run

tetris --ascii-only         # uses [] as preview cell
# or
tetris --preview-chars 'XX' # uses custom characters as preview cell

If you want to skip the level prompt, you can start the game immediately via

tetris --level n

Lastly, to see the current high score, you can run tetris --high-score. And of course, see tetris --help for help.

Development

Enter the development shell with nix develop.

Format the source with fourmolu --indentation 2 **/*.hs -i.
