# Creating The Tiles From JavaScript This step places the game tiles randomly. Change `main.js` to the following: ```js {{#include main_tiles_from_js.js:main}} ``` The code takes the list of tiles, duplicates it, and shuffles it, accessing the `memory_tiles` property through the JavaScript code. As `memory_tiles` is an array, it's represented as a JavaScript [`Array`](https://slint.dev/docs/node/). You can't change the model generated by Slint, but you can extract the tiles from it and put them in a [`slint.ArrayModel`](https://slint.dev/docs/node/classes/arraymodel.html) which implements the [`Model`](https://slint.dev/docs/node/interfaces/model.html) interface. `ArrayModel` allows you to make changes and you can use it to replace the static generated model. 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.
