As briefly commented on, you can be wholly nostalgic and simply play using the very same rules that I experienced for the first time back in the late 70s, a few years after its first publication.

Since it arrived in the post we’ve played it several times with different numbers of players and different time limits. Guards cannot block entrances to rooms and must not impede the movement of PoWs inside the grey prison courtyard area by remaining in doorways or passages between turns.

The prisoner starts from anywhere inside the grey area of the board (the inner courtyard) and must reach one of the safe targets outside of the castle walls within the number of throws specified. Perhaps because of its simplicity, the game has attracted many home-brewed variations and "house-rules.

Dice rolls determine how far a pawn can move, but if you roll a 3, 7 or 11 you also pick up an action card.As a last resort, an Escape Officer may elect to use the "Do or Die" card, which allows for one escape attempt without the need for any Equipment.

What seems to me the strangest tweak is that each player is given a complete Escape Kit card to begin the game. Beneath the board, the rest of the contents are securely held in the substantial inserts, but the main packaging of the components has understandably been retained - a simulacrum of the Red Cross parcel that POWs received simply should not and has not been changed. Post more Guards but only on the vacant black circles, from his reserve in the Kommandantur: as many as he wishes up to the total number of this throw.If a guard sees a POW entering or exiting a forbidden room, a guard can arrest the POW by moving a guard into the same circle as the POW. POW’s have an advantage over the Security Officer here, as, if playing with more than two players, they can choose to either discard one of their Opportunity Cards or they can pass it over to another POW. This can aid your bid for freedom if you’re a POW or help prevent escape if you are the security officer.
