# Creating The Tiles From Rust The tiles in the game should have a random placement. We'll need to add the `rand` dependency to `Cargo.toml` for the randomization, using the `cargo` command. ```sh cargo add rand@0.8 ``` What we'll do is take the list of tiles declared in the .slint language, duplicate it, and shuffle it. We'll do so by accessing the `memory_tiles` property through the Rust code. For each top-level property, a getter and a setter function is generated - in our case `get_memory_tiles` and `set_memory_tiles`. Since `memory_tiles` is an array in the `.slint` language, it's represented as a [`Rc`](https://slint.dev/docs/rust/slint/trait.Model). We can't modify the model generated by the .slint, but we can extract the tiles from it, and put it in a [`VecModel`](https://slint.dev/docs/rust/slint/struct.VecModel) which implements the `Model` trait. `VecModel` allows us to make modifications and we can use it to replace the static generated model. We modify the main function like so: ```rust,noplayground {{#include main_tiles_from_rust.rs:tiles}} ``` Note that we clone the `tiles_model` because we'll use it later to update the game logic. Running this gives us a window on the screen that now shows a 4 by 4 grid of rectangles, which can show or obscure the icons when clicking. There's only one last aspect missing now, the rules for the game.
