What it does
The server rejects any answer naming a direction that wasn't offered, and checks the returned probabilities actually sum to one before the snake moves.

Jev Snake
Server-side snake where every move is one typed choice question, with the board, snake, and food as the state.

How you can use it
Sketch your own grid game where an artificial intelligence steers a character. Draw the board and mark where targets or obstacles sit. A developer can write code that checks the board, finds safe open steps, and asks Jev to choose the best direction.
Your developer links the game to the TypeSafe AI service using an access key stored safely on your private server. Because the game contacts the outside service for every single step, the character can only move as fast as each reply arrives.
