1 - Addition


Master Navigators/Road Rally Navigators

Start with the map reference of TC1 then progressively add the value of the clues. You should have ended up with the following list of in order via map references.

1084490808  1145991413   1338991513   1353992303   1395992763   1419994633   1500095000   1759495478

There were two accepted possibilities of RC1 and RC2: 6/1 or 8/3. Some competitors rightly argued in my opinion that there was no definitive way of telling whether a double gradient was in fact two singles. The acceptable answers are based on one interpretation or another.

RC1 - 6(8), RC2 - 1(3), RC3 - 5, RC4 - 6, RC5 - 2

From the last reference in part 1 continue on the same theme except that the clues were values encoded in different number bases. The decoded values were:

2 - Subtraction


Master Navigators/Road Rally Navigators

Start with the map reference of TC2(Out) then progressively subtract the value of the clues. You should have ended up with the following list of in order via map references.

(2559400558) 2485400278 2441999598  2370999263 2316498793 2300097408 2166996000 2145496000

The first was bracketed meaning avoid rather than via.

Two acceptable answers to RC2 depending upon whether you counted a double gradient as two singles.
For Experts I have now allowed an alternative route via Slade (2097) which also (arguably) relies on the crossroads in 2196 being staggered. Hence a value of 5 for RC3 was permitted. Not allowed for Masters since Route Card 1 part 2 went through Slade.

RC1 - 3, RC2 - 2/4, RC3 - 3(E5), RC4 - 58, RC5 - 4

3 - Multiplication


Master Navigators/Road Rally Navigators

The spot heights were coded by multiplying their digits together, giving:

163 83 149 127 148 138 175 48 55 48 72 4 83 22 71 5 13 4 4

Two possible answers to RC4 because of disputed junctions in Seaton.

Tough multiplication. Did you do it by long hand? I used a program I found on the Internet.

The answer to the sum was:

13711712513313999817928721711286710520517417311686153

then break it down to via spot heights

4 - Division


Master Navigators/Road Rally Navigators

The clues were the division of the first digit of a grid line by the second digit. This gave the following sequence of grid lines to cross:

93 34 34 94 34 95 33 96 33 96 96 34 35 96? 96? 96 36 36 95 35 95 95 35 94 94 94 36 36 36 

RC5. Usual problem of deciding which RDs actually touched the route.

break apart for grid lines to cross, thus:

5 - Not Map Bits


Master Navigators/Road Rally Navigators

The map bits were bracketed - you had to avoid them. On map edition D there was a shorter white route which bypassed Thorncombe giving an answer 3 for RC3.

There is a shorter route through Waytown which some Experts used not knowing that it clashed with the Masters route in RC6. Hence an acceptable Experts value of 2 for RC1.

8 - You're A-maze-ing


Master Navigators/Road Rally Navigators

From the starting TC (cross on the right) to the finishing PC (cross on the left) via the grid squares. Leave a grid square via a green blob, enter by a red blob. You had to be careful that you used all the blobs.
