+# rs2048
+A TUI 2048-game, written in Rust.
+2048 is a simple logical game. If you don't know it yet, you can read it's [wikipedia page](https://en.wikipedia.org/wiki/2048_(video_game)).
+
+## Features
+ - Basic features: collapsing contacting and same tiles on swipe, and putting a new tile to the board.
+ - Randomly choose between 2 and 4 when adding new tiles.
+ - If the table hasn't changed after swipe, no new tiles appearing.
+ - Tiles coming from collapsing collapse further only after the next swipe. (E.g. 2 2 2 2 collapse to 4 4, and only after a second swipe collapse to 8.)
+ - Game Over detection
+
+## Compatibility
+As it has only cross-platform (and statically linked) depencies (ncurses and rand), it should work on almost every OS.
+However, creating Windows builds is tedious, so I'll provide only Linux builds (I'll may reconsider).
+If you don't have Linux installed - and don't want to install it - you can use [onworks.net](https://www.onworks.net), that provides a virtualized Linux system that you can control from your browser.
+
+## Running
+It don't have any runtime dependencies, so you can download the [binary]() from the Releases page, open a terminal where you've put the binary, and start it with `./rs2048`.
+
+## Building from source
+First, clone the repo via git (if you don't have git, and don't want to install it, you can download the source code from GitHub directly):<br>
+`git clone https://github.com/Zoldszemesostoros/rs2048.git`<br>
+Then install cargo (rust's build system), and the ncurses developement package:<br>
+`sudo apt-get install cargo`<br>
+`sudo apt-get install ncurses-dev`<br>
+then go to the rs2048 dir:<br>
+`cd rs2048`<br>
+build the project<br>
+`cargo build --release`<br>
+and run the binary<br>
+`build/target/release/rs2048`<br>
