2^N (terminal)

2048, generalised, in a terminal: where the game started. The third version beside web/ and wii/, on the magmacrunch engine's terminal backend: a cabinet in the magmacrunch arcade and its own command, the same either way.

pip install -e ".[dev]"
two-to-the-n                  # or python -m two_to_the_n
two-to-the-n --mode 4         # straight to a target of 16
two-to-the-n --mode endless --play

Keys

Two equal tiles that touch merge into their sum, and the merge scores the tile it makes. The game ends when a tile reaches 2^N, which is a win, or when the board is full with no pair left. The newly dealt tile lights up for a moment. Past 2048 the tiles cycle through the page's plasma.

It is the browser's game

two_to_the_n/rules.py is web/js/game.js plus the three lines of web/js/main.js that make a slide into a turn: slide, and only if anything moved, deal a tile and check for the end. tests/test_oracle.py checks it: tools/js_oracle.mjs loads the website's adenosine-puzzle.js and web/js/game.js with Math.random seeded, plays a few hundred games across every mode, some mashed and some played into a corner past 2048, and the test replays every move through the port and requires the same board, score and ending after each one.

The oracle needs the website, for the bundle. It finds it the way tools/link-shared.mjs does: ../shared, $WEBSITE, ../../website, ../../../web/website. CI checks the website out beside the game.

The browser's choices are copied rather than improved, because both versions file scores the same way:

• One board, 2n, with the mode beside each score as difficulty, and a top ten per mode. A score is asked for initials only if it makes its own mode's ten, as the page asks.
• 2-bit mode never deals a 4, which would be its target, while the value draw is still taken so the odds elsewhere match.
• Reaching the target ends the game, as a win, after a half-second pause to see the tile that did it.

Change any of these in web/js/game.js and here together, and the oracle will hold the two to each other.

Needs a 67x21 terminal.
