Lighting the diyas…
A free 3D fireworks simulator that runs in your browser. You stand on a river ghat at night with every Diwali cracker in your pocket: phuljhadi (sparklers), anar (flower pots), chakri (ground spinners), rockets, mirchi bombs, green sutli bombs and ladis. They never run out, and up to six can go off at once.
Drone and laser shows fly over the river every few minutes while you play. Nothing to download, no login, no smoke, and it works on most phones. For the full Diwali night, with 108 diyas to light and a finale, play Virtual Diwali.
