The Story
SAI-1 is a puzzle game set in the futuristic world of the year 2100. You take on the role of a robot named SAI-1, a machine created entirely by a cutting-edge AI using the latest technology.
SAI-1 was designed and assembled in a race against time to compete in STM 2100—a prestigious tournament dedicated to discovering the world's most intelligent robots.


Intriguing Challenges
Each round of the STM 2100 tournament presents a completely unique challenge. These puzzles are designed around a clever principle: the solutions are remarkably simple, yet they remain difficult and engaging because they require players to think outside the box.
"Experience that 'Aha!' moment as you uncover solutions that are surprisingly straightforward yet brilliantly hidden."
