They are addictive, cause hallucinations and turn us into antisocial zombies - no question, computer games are often considered evil!. Unless, of course, you can play them analogue ;).

In fact, the Retro Gamer stacking game is almost as much fun as Tetris, which it somewhat resembles due to the appearance of the stackable blocks. However, you need not only good concentration, but also a steady hand and one or more additional players. As described in the instructions, the pieces are divided evenly before you have to take turns stacking them on the blue base. This is more difficult than it looks. If the structure gets out of balance and falls over, the player who placed the last block loses.

We would like to point out that you may dream of stacked, colourful shapes at night. But this is completely harmless, we promise...
