Watch the video below for a quick introduction to 10 to 20. It demonstrates the main objective, basic controls, and useful techniques to help you get started. Play the video before launching the game, pause whenever you need a closer look, and replay any section that moves too quickly. Then try the steps yourself in the game above.

To start playing, select the Play button in the game area. Most games use a keyboard, mouse, touchscreen, or a combination of these. Look for instructions on the title screen or in the game's pause menu, since controls and goals vary from game to game. Common keyboard controls include the arrow keys or WASD for movement, Space for an action, Enter to confirm, and Escape to pause. On mobile devices, tap the on-screen controls and rotate your device if the game recommends a different orientation.

If the game does not start, first wait a few moments for its files to load. Then select Reload Game and try again. You can also refresh the page, check that JavaScript is enabled, and temporarily disable browser extensions that block scripts, cookies, or embedded content. For games that provide the option, Open in new window may work better when a browser blocks third-party content. A stable internet connection and an up-to-date browser usually provide the best experience.

Use Fullscreen for a larger play area. Press Escape to leave fullscreen mode. If sound is missing, check the game's audio controls, your device volume, and whether the browser tab is muted. Some browsers require you to interact with the game before audio can begin. If performance is slow, close unused tabs and applications, exit fullscreen, or try another modern browser. Progress may be saved in your browser, so clearing site data or using private browsing can remove saved progress. Never enter personal or payment information inside a game unless you understand and trust the request.
