# Creating The Tiles From Rust This step places the game tiles randomly. The code uses the `rand` dependency for the randomization. Add it to the `Cargo.toml` file using the `cargo` command. ```sh cargo add rand@0.8 ``` Change the main function to the following: ```rust,noplayground {{#include main_tiles_from_rust.rs:tiles}} ``` The code takes the list of tiles, duplicates it, and shuffles it, accessing the `memory_tiles` property through the Rust code. For each top-level property, Slint generates a getter and a setter function. In this case `get_memory_tiles` and `set_memory_tiles`. Since `memory_tiles` is a Slint array represented as a [`Rc`](https://slint.dev/docs/rust/slint/trait.Model). You can't change the model generated by Slint, but you can extract the tiles from it and put them in a [`VecModel`](https://slint.dev/docs/rust/slint/struct.VecModel) which implements the `Model` trait. `VecModel` lets you make changes and you can use it to replace the static generated model. The code clones the `tiles_model` because you use it later to update the game logic. Running this code opens a window that now shows a 4 by 4 grid of rectangles, which show or hide the icons when a player clicks on them. There's one last aspect missing now, the rules for the game.
