Most game features are the same, but there are a few differences:

Controls

• Netflix Game Controller: Games on TV has access to the Netflix Game Controller, which allows you to play games on Netflix using your phone or mobile device as a game controller. However, Games on TV is in beta, and depending on your device type, your TV or browser may not be supported at this time.
• Mouse & Keyboard: Games on TV on your browser can be played using a mouse and keyboard.

Date & Time

• The date and time do not show at the bottom right, as the Games on TV system would not reflect the player’s local time.
• On Games on TV players, ‘Perpetual Daylight’ is the default setting to compensate for this limitation, but this can be changed in the settings menu.
