WHAT PLAYERS SAY
"Beautiful minimalist 4-player radial tetris, with x-ray powerup for added depth."
"For the fans of Tetris, this one is a real breath of fresh air."
"Like someone put Tetrominos and Super Hexagon in a blender."
THE REAKTOR STORY
One day, a bored engineer at the Chernobyl nuclear power plant modified the SKALA control program with a score function so it would be more fun to play. He began making larger and larger reactions, until one day he messed up and caused a meltdown.
But he was addicted.
Years later, he sneaked back into the rubble, stole the modified control code, and published it as an internationally acclaimed video game called REAKTOR.
