I don’t want to contemplate how much time I wasted in the late 1980’s playing Tetris on an ancient Windows PC. But the fascination for spinning and stacking the seven colourful tetrominoes has never really left me, even though I’ve not played the game in years. As a homage, I decided to build Tetris Tower, the HQ of a successful game development company in Micropolis. I had already decided where each piece would go, and then had to order in many 1×1 tiles to make it happen.
