You can worship Tetris anywhere you can take an electronic device. Tetris is available for most computers and video game systems. Always try to worship with a pure version of Tetris, though, because False Idols corrupt. It's better to abstain than worship a False Idol.
By popular request, we have sanctioned the following prayer that you may recite before worshiping.
Oh, Tetris, thy Glory great, Give us today our daily blocks, So that we may clear them. And give us strength, Through our gaps and mistakes, To obtain a tetris. Start.
