Bruce Tomlin brings us a new Megadrive/Genesis game called “Tubes”.

Your job:

* make a completely capped group of pipes to score
* cross pipes don’t affect pipe capping of the other pipe in the same tile
* the more tiles in your group, the higher your score (triangle number: 1, 3, 6, 10, 15, 21, etc.)
* use bombs to destroy unusable tiles
* game is over when your new tile gets stuck above the top row
