EDITOR'S LETTER
Every 1990s gaming magazine had a page of tricks nobody knew really worked. This issue is the opposite: every number here came from a real call. The first ideas now have playable versions: Twenty-One, Silent Oracle and Akinatee are in the free full games section.
The engine is called Jev, by TypeSafe, released on September 15, 2026. It does not write or chat. You provide context and closed questions (“which one?”, “yes or no?”, “how much, from 0 to 4?”), and it returns an answer with a probability, in under half a second, for pocket change.
In the first week, people already had Jev playing Doom, Mario, Civilization II and chess (like a beginner: it judges, it does not calculate), controlling stealth-game guards and identifying which character a player is talking to. We looked for something else: games that only work well because of the judge, and that an ordinary chatbot would not handle the same way.

SIDE B
The ideas that did not pass the reader's review, and why. We keep them because sometimes what survives one idea becomes the next game.
