This puzzle consists of a number of pieces called quanta (plural of quantum) which are represented by white diamond shields with a blue cross and border. They can move freely over the empty spaces (light purple) but are (usually) blocked by the walls. The walls come in 5 colors: red, blue, yellow, green, and brown. The quanta cannot be moved individually, but can only by moved simultaneously in a synchronized manner. The object of the puzzle is to make all of the quanta disappear. (Note: the squares of the board are adjacent orthogonally only. There is no diagonal movement.)
 
At the bottom of the board is a row of 14 buttons. You play the puzzle by clicking on the buttons, not by moving the pieces. Click on one of the 4 light blue buttons with arrows at the right end of the row to move all unblocked quanta in the direction of the arrow. Quanta are blocked by walls and any other blocked quanta, but not by moving quanta. This means that if one quantum in a row of adjacent quanta can move, then all of the others will move with it in sequence. Next in the button row (moving to the left) are 4 orange buttons with arrows. Clicking on one of these will cause all of the quanta which are blocked by a wall (only) to make a quantum jump over the wall, provided there is an empty space on the other side, or another jumping quantum (but not a stationary one). Again, this allows an entire sequence of quanta, separated by walls, to jump together. Next are 2 purple buttons with double arrows. Clicking on one of these causes every quantum which is adjacent to another quantum in the given orientation (horizontal or vertical) to disappear. Finally, at the left end of the row are 4 colored buttons (blue, red, yellow, green) with black X's. Clicking on one of these causes all quanta which are adjacent to a wall of the corresponding color to disappear. (The brown walls are inert.)
 
The most important rule of the puzzle is that each of the 10 leftmost buttons can be clicked only once, after which it is blacked-out. The 4 rightmost buttons (ordinary movement) may be clicked as often as needed.
 
You win when there are no quanta remaining.
