Reliquarium is a very unique set of four 3D slider puzzles, all with a Crystal Skull theme. Three are my own creation, while the fourth is a well-known Grabarchuk slider puzzle. A reckless raider from Indiana has plundered tombs and displaced ancient relics. The objective is to return each relic to the center of its cubical box by rearranging the numbered blocks back into their proper order. Dragging the cursor rotates the cube for a better view angle. The mouse wheel zooms. Typing a number 1..8 selects a block to move, 0 selects the relic itself. Then use the keys {u,d,l,r,f,b} to move the selected block ( Up, Down, Left, Right, Forward, Backward ).
