Blodia

Blodia aka Diablo on some systems is a puzzle game with similarities to sliding block puzzles. Each level is composed of a number of tiles and every one has a part of a pipe (straight or angular) on it - except one which is just a black hole. In one tile a red ball starts rolling and all tiles it rolls through become blank.

The goal of each level is to let the ball roll through all pipe parts without meeting the hole or a blank tile. To ensure this, the player can move the parts while using the hole as buffer. So, as example, if the player clicks on a tile which is a few tiles away from the hole, all tiles between the clicked tile and the hole are moved by one towards the hole. Then the hole is at the place where the player clicked on. At the start of a puzzle, rolling out of the level boundaries is also deadly, but after a certain amount of tiles are cleared the ball comes out at the opposite side of the playfield.
