YS Flight Simulator Web

How to play

1. Follow the goal and instructions shown in the game.
2. An unofficial BSD-licensed browser flight-simulator port with a documented peer-to-peer multiplayer option; session availability follows the host.
3. Use the external host's game menu for detailed rules and any restart or save options.

Make your move

• The port documents keyboard and mouse-as-stick controls plus gamepad or joystick support; review its current guide before flying.
• Check the host's Help or Controls guide for every key and touch action.
• Denny Games has not verified a complete external game session or device compatibility.

A small head start

• Read the host's help and controls before your first move.
• Read the host's controls and rules before starting a longer run.

Compatibility notes

This unofficial Emscripten/WebAssembly port documents a first load of about 25 MB, keyboard/mouse and gamepad controls, and browser-to-browser multiplayer. It says a service worker can support offline use after loading. The page returned HTTP 200 on 2026-10-16; a complete flight, multiplayer session, controller and device behavior were not tested.

Denny Games has not verified this external build's gameplay, browser compatibility, controls or save behavior. Check the host's current requirements.

Play style: Check host controls. This game runs on an independent host or browser build. Denny Games does not manage its account, session or saves; see the notes above for how this build handles them.
