akioi-2048

Pure Rust 2048 engine with multiplier tiles and score tracking.

Features

• Classic 2048 mechanics
• Special multiplier tiles: -1 (x1), -2 (x2), -4 (x4)
• Simple functional API for simulations/AI
• Detects victory (65536 tile) and game over

Rust API

init() -> [[i32; 4]; 4]

Create a new 4x4 board with two starting tiles.

step(board: [[i32; 4]; 4], dir: Direction) -> Result<([[i32; 4]; 4], i32, State), String>

• Apply a move.
• On success returns (new_board, delta_score, state)
• state is an enum: State::{Victory, GameOver, Continue}.
• Use Direction::{Up,Down,Left,Right} for dir.

Example

use akioi_2048::{init, step, Direction, State};

fn main() {
    let board = init();
    let (next, delta, state) = step(board, Direction::Down).unwrap();
    println!("delta={delta}, state={state:?}, next={next:?}");
}
