Recently encountered a game that made me think of this thread.
King of the Bridge is a game where you play an unfair chess variant with partially-secret rules and the opponent sometimes cheats. I reached the first ending in ~40 minutes. Getting there without ever losing a match seems like it ought to be possible with great paranoia plus some luck.
If you want to try this you should probably avoid looking at the store page in detail, as some of the secret rules are revealed in screenshots.
