Octocube How to Play & 3 Player Playthrough

About Octocube, from BoardGameGeek:

In the depths of the seas, octopuses compete for treasures left behind by surface dwellers; they collect and stack them in their secret lairs. In Octocube, you take the form of a cubic octopus, rolling from stack to stack of tiles to magnetically gather as many objects as possible. Choose them carefully while blocking your opponents. During the game, score points each time you clear the faces of your cube, and at the end of the game, win majorities to boost your score. -description from the publisher
