Similar to the Duo, just twist each tip and the adjacent center follows. But it gets really tough as you've got eight sides to match, not just four - double the challenge!

To use the Pyraminx Diamond, hold it in your hand and start by twisting the tips. As you do this, the adjacent centers will move along. Try to match all eight sides. Be patient as it can be tricky. When you're done playing, store it in a dry place to avoid any damage. Don't force the twists too hard as it might break the puzzle. If it gets dirty, you can gently wipe it with a dry cloth.
