Puzzle & Dragons is a ridiculously popular mobile game in Japan that tasks players with matching coloured orbs in order to take down enemy monsters. If you've played Pokemon Shuffle before, it's just like that. To help with the trickier stages, YouTube user Junya Sakamoto has developed a robot that can play the game for him. Oh, and it's unbelievably good. As Kotaku reports, a connected laptop is able to analyse the board and pick out the optimum combos, triggering a flurry of moves that would be almost impossible to replicate with your pinkie. Color us impressed, although we suspect developer GungHo won't share our enthusiasm.
