Is it possible to run phaser games offline?

Can I develop a game and use the static generated HTML to run the game offline from a mobile device?

Thanks,

Yep. Look into packaging your game with Cordova or PhoneGap or something similar.

Hi @Annas_Abu_Mukh,
Yes.
One solution is convert your game into a PWA (progressive web app).
Take a look at this tutorial:
