The Crossing Chains puzzle challenges you to think about making connections between circular pieces. At each level you will find a set of black circles that need to be connected to each other in a continuous chain. The beginning of the chain is a colored circle, draw a line from it, connecting the other circles along the way, they will become colored and serial numbers will appear on them. This is important because in subsequent levels black circles with locks and numerical values will appear. To open such a lock, it is necessary that a roc with a value of one less in Crossing Chains appears nearby.
