Introduction to TAPE
The Adam Park Enigma (TAPE) is a series of 5 mystery caches placed around the Adam Park residential estate. 4 of the caches (Parts 1 – 4) are ordinary mystery caches where you have to solve a puzzle to find the coordinates of the final cache. The puzzle for Part 5 is requires information placed in the first four caches, so you will need to complete the first four caches before you can attempt Part 5.
Each part of the series contains a write-up of the history of the area and a description of the Enigma cipher, which is the code that needs to be cracked to obtain the final cache in the series. You will find the puzzle that you need to solve for this part of TAPE near the end of the listing
The History of Adam Park (Part 3)
Just a little north of Adam Park is the junction of Sime Road, Lornie Road and Adam Road, and while the Cambridgeshire Regiment were occupied defending Adam Park, the Suffolk Regiment were stationed here. This part of the history of Adam Park centres on this area.
The junction of the three roads in 1942 was pretty much as you see here today. The Singapore Island Country Club golf courses lay at the north corner of the junction, and just north of them were the forests of the Catchment Area. This area was a strategic area as the headquarters of the Allied Forces in Singapore was just up Sime Road, protected by pillboxes and trenches. The Suffolk Regiment of the 18th Division was tasked to defend the surrounding area from the Japanese.
However, unlike Adam Park, the junction was not well-sheltered and was an easy target for the Japanese aerial bombing. Before the Japanese offense on the area, the Japanese Air Force dropped huge amounts of bombs on the areas surrounding the junction. The soldiers nicknamed the area Hellfire Corner as a result.
The Japanese forces approached as the Jurong – Kranji Defence Line faltered, and by the 14th February 1942, the Japanese were no more than a mile from the area. The headquarters of General Arthur Percival and his command was hastily moved from Sime Road to the Battle Box at Fort Canning, while the men from the Suffolk Regiment were left to defend the junction, Bukit Brown and Sime Road from the Japanese. It was not long after that that they suffered the same intense battle as did their counterparts in Adam Park.
The Enigma Cipher (Part 3)
The inventor of the Polish Bomba: Marian Rejewski
Luckily for the British, knowledge of the Enigma Machine had made its way to England. The British were more than happy to have both duplicates of the machine and the expertise (in the form of the Polish cryptographers Marian Rejewski and his students, Henryk Zygalski and Jerzy Różycki) to operate the machine. However, there was the issue of the increased complexity of the machine settings that the Germans had recently introduced which threatened to throw a spanner into the works.
Inventor of the British Enigma Bombe: Alan Turing
The British then set up their own cryptographic initiative at Bletchley Park, to crack the Enigma cipher. They recruited Alan Turing, a brilliant mathematician, to build a machine that would be able to crack the Enigma cipher in as short a time as possible. Recalling that the settings were changed every day, a good decrypting machine was needed to be able to crack the code within a few hours. Turing worked on the problem, and managed to come up with a solution that exploited a flaw in the Enigma encryption process (which will be explained in Part 4).
Using this new-found information, Turing and the engineers at Bletchley Park set up on building a machine, named the “Bombe”, as a tribute to the work done by the creators of the original Polish machine. The Bombe was effectively a primitive parallel processing device, which ran through each of the thousands of rotor settings to find a possible result. However, since this, too, takes too much time, Turing had to also figure out a way to eliminate impossible settings quickly…
TAPE Puzzle Part 3: You Need To Be More Flexible!
Cracking the Enigma cipher was no easy task, and Turing and the engineers at Bletchley Park had to think both logically and laterally to crack what many thought to be the unbreakable code.
This puzzle may require you to think flexibly and mathematically like Turing, especially if you are keen on getting the rotor settings for the final part of TAPE.
You will need to cut out a thin strip of paper (the longer, the better), and copy down exactly the shapes and numbers you see in the image. Note that each triangle is an equilateral triangle (internal angles of 60°) and there must be 19 triangles each on both sides of the strip. Follow the instructions in the image carefully: the “back” orientation is a result of flipping the “front” along the longest edge.
Next, fold along the black lines to obtain a very particular hexagonal structure and you must end your construction of the hexagon by gluing the faces marked "glue" to each other. Ensure that the "front" is always facing upwards when folding. Do it any other way, and you will have difficulty solving this puzzle.
You will really need to flex some of those origami finger muscles to get the right shape structure. Play with the resulting hexagon for a while and the coordinates will appear. Have fun!
