Emerald V3 is a stunning new addition to the intermediate range, designed by Chris to be a step up from Blue with unique elements that will challenge you to think outside the box. If you enjoyed solving Blue, the Emerald is a more challenging version with the same level as Blue but four points as the compass. Emerald is a carefully crafted and enjoyable maze to solve; it will put your problem-solving and mapping abilities to the test, and it will make an excellent addition to your puzzle collection!
