into my head.? This games has different level. Use arrow keys or mouse to control. Definite 3D look. There is a grid of different colored squares and you roll a multicolored block around this grid. When the side of the block matches the colored square it is picked up by the block. The empty squares are replaced with new different colored squares. There is a strategy to this game. You can learn to move say up three, over two and down one and that would have matched the same color square to the upside of the block when you started the move. Anyways any suggestions would be helpful. Like I said the name endorphan keeps popping into my head but have not been able to find game by that name. Thanks for your help.

this is 3d and has "endorphin" in it... i'm not sure it's what you're after. i'll edit my answer if i find anything more useful:
