The 2003 classic is light enough to run in a browser tab. Most of these ports connect to live multiplayer servers, so you can jump into a match without Steam or an install.

Counter-Strike began in 1999 as a fan-made mod for Valve’s Half-Life, created by Minh Le and Jess Cliffe. Valve acquired it in 2000, and version 1.6, released in 2003, became the build most players still picture when they think of the original. Two teams, terrorists and counter-terrorists, fight short rounds built around planting or defusing a bomb or rescuing hostages, and the money you earn in one round pays for weapons and armor in the next.
By modern standards the game is light, which is why it works in a browser at all. Community developers have compiled compatible engines to WebAssembly and run real servers you can join from a tab.
Two listings cover CS 1.6. Both are unofficial fan projects with no connection to Valve, and neither asks you to supply game files.
On a phone, Spawn and CSJS are the hosts that mention touch controls. The others are built around a keyboard and mouse. Because these are fan-run sites, any of them could change or go offline without notice.
