Polygures is not a Tetris clone; it's an evolutionary experiment. The story of Polygures begins in 1996, where Russian mathematician Alexander Iglitsky published an article in which he explained his "universal theory of Tetris." In December 2011, Ilya Chentsov reached out to Iglitsky and found out he was still eager to implement his games when Chentsov told him about all the current digital channels for distribution.

The two have provided a free, downloadable demo of one of those Tetris-like games, codenamed Yakoris. While it supposedly runs in Windows XP, I had to play it using DOSBox.

What I thought would be an experience similar to Tetris, and one that I could "win" at with minor adjustments, turned into frustration and self-loathing. The figures (can't call them shapes) keep rotating, each time they drop down a line. How can my brain plan for this!? Surely, this was a glitch.

Chentsov confirms that the figures are supposed to change. "If you imagine the grid, it's deformed, so each 'square' of the figure changes as it passes down to fit the cells [illustrated here in the "Twisting the Space" section]. In normal Tetris, the grid is obvious. Here, you have to imagine it to play successfully."

I'm pretty excited to mess up my brain more trying to play the other Tetris-likes. While waiting for more releases, check out this new video of Polygures, narrated in whispering Russian with an English transcription, and give Yakoris a try.
