Crown of Siam

Crown of Siam (COS) is Narongrit Uppalabat’s browser MOBA, featuring heroes from Thai legends such as Khun Phaen, a mechanical Hanuman and Phayak. The creator describes one-on-one matches and bot practice as its central format. This introduction uses creator information and entry-screen checks; combat has not been tested.

Thai heroes and MOBA-style systems

The original post describes last hitting, denying, wards, a shop, couriers and runes, with online 1v1 and ranked play for registered users. The announcement lists 3v3 and 5v5 as future plans. These are creator-supplied details, not a test confirming that every system is available and working.

Guest access and the limits of the check

The October 14 check entered as a Guest and reached bot-practice setup, with hero and difficulty choices. It stopped at the preparing-arena screen, so combat remained unverified. The October 16 check confirmed that the title, hero model and Guest form render as shown in the image.

The Guest screen says bot practice runs locally and the name is stored on the device, while online and ranked play require registration. This check did not register, sign in, test online play, verify persistence or test mobile devices. Treat this as an overview of the test project rather than a verdict on match quality or balance.

The creator’s AI-development account

Narongrit says he develops the game alone with help from Codex and Claude. The announcement describes a testing phase, with further balancing and characters planned. This development information comes from the creator’s original post
