While the method of printing maps on silk, and hiding them in board games was ingenious; it isn't necessary to follow that exact pattern. The idea of finding a way to covertly supply the means of escape, though, is merely a matter of finding what won't be noticed. In that sense, it is still very much a part of modern detention.
There is an almost endless amount of literature on war tactics and strategy, and though there have been many changes with technological improvements such as unmanned drones, the fundamental nature of warfare has not changed dramatically. In fact, with the surveillance and information gathering technology that now exists, a modern implementation would likely be far more effective than its WWII predecessor.
During WWII, the board games had a planned hiding place for maps and money so that the prisoners could be helped along with secret messages. The same ploy could be used today with modern day prisoners by smuggling messages or money in various common objects such as books or cards or food.
The problem with famous stories like this one is that everybody has heard it. Once everybody has heard it, the people in charge of making sure that it doesn't happen again are on the lookout for it. I'm sure that the British secret service has a new awesome plan that will only work once, though.
