| How do I solve a Kwon-Tom Loop puzzle? |
| Try working through the tutorial, as that will explain the basic rules and show
you how a typical puzzle is solved. If you've ever tried a Slither Link or Loop
The Loop puzzle, the rules here are the same. |
| |
| I can't see the puzzles. |
| Make sure you are using a modern web browser with Javascript enabled. The site
has been tested with Internet Explorer and Firefox. |
| |
| I'm dragging between dots but lines don't always appear. |
| Try clicking on the space between the dots, where you want to put
a line or cross - dragging won't work!
Click once in a gap between dots to place a line there. To change
it to a cross, click once on the line. |
| |
| Double-clicking is too slow! Can you help? |
| Yes. If you hold down the 'shift' key while you're clicking, that
will have the same effect as if you'd double-clicked. Shift-click
makes a gap become a cross, a cross become a line and a line become
a gap. You can also use the right-mouse button to achieve the same
effect. |
| |
| Can I do more than just the current puzzle? |
| If you're a registered user you have access to the entire archive of
puzzles on this site. The 'archives' link at the top of the page will
allow you to see puzzles which are at least a week old, along with their
solutions. The 'home' link gives you access to the current week's worth
of puzzles - it's these that are counted for the leaderboard.
If you don't want to register, you won't be able to see the past week's
puzzles - the 'current puzzle' link will show you the puzzle from one
week ago. In the 'archives' you'll also have access to the past 15
Monday (easy) puzzles, as well as all older solutions and the current
'Beast Of The Month'.
The reason non-registered users can't
see today's puzzle is that otherwise they might solve it, then log in
and use their solution to get a really quick time for the leaderboard. |

| What does the 'Fix Position' button do? |
| This is a bit of a cheat to help people whose brains can't cope with working
out what the consequences of putting a line or cross might be. It'll turn all
existing lines and crosses green and won't allow them to be changed. You can
then try out a move and see what happens, resetting back to the fixed position
if it all goes wrong. 'Un-Fix' will turn the green lines and crosses back to
black and allow you to change them again. |
| |
| What does the 'Shading' option do? |
| When 'shading' is on, you can alter the colour of the squares by clicking
in the middle of them. Some people prefer to work this way, marking
squares that they know are 'inside' the loop in one colour and squares
they know are 'outside' the loop in another colour. You still need to
draw the lines in to submit your solution, of course. Pushing the shading
button will switch shading styles from 'off' (the default), to 'small'
where just the number is shaded, to 'large', where more of the square
is shaded. If you're logged in, your shading style will be remembered
for future puzzles. |

| Where's the solution to yesterday's puzzle? |
| The solutions aren't published until a week after the puzzle is first
displayed, so check back at a later date. |
| |
| Could you explain the difficulty levels? |
| The level of difficulty is displayed next to a puzzle, ranging from 'easy'
up to 'very hard'. Easy puzzles tend to require very straightforward logic
to solve, so not much 'thinking ahead' is needed. On the other hand, puzzles
ranked as 'very hard' often need some in-depth analysis of potential moves
to determine the correct solution.
All puzzles larger than a 10x10 are automatically rated as 'big', rather than
a specific difficulty level, because they'll take a while to do regardless
of how hard they are. |
| |
| Why are puzzles on a Monday always easy? |
| Each day of the week has a specific difficulty level and puzzle size assigned
to it. Weekdays (Monday to Friday) are always 10x10 puzzles, ranging from
easy on the Monday up to very hard on the Friday. Both Saturday's and Sunday's
puzzles are always larger than 10x10, and so are rated 'big'. |
| |
| Is it possible to save more than one position? |
| No. You have just one 'save slot' that you can use at any time to store
the current puzzle state. The link to load your saved position can be
found on the home page. |
| |
| I solved a puzzle in about 20 minutes, but it says I took 26 hours! What's going on? |
| The time it takes to solve a puzzle is measured from the very first time you see
it until the correct solution is submitted. Even if in the meantime you've
saved your position, gone off and done other things for a day (maybe even other
puzzles), then come back to it. The reason it's done like this is to stop people
from obtaining a fast time on difficult puzzles by printing them off, solving
them on paper, and then coming back to quickly fill in the solution. |
| |
| Could there be more than one solution to a puzzle? |
| Theoretically this shouldn't be possible. All of the puzzles have been designed
in such a way that only one possible solution fits the original layout. If you
find a puzzle which appears to have more than one way to solve it, try doing
both and double-checking that every square has the correct number of lines around
it, and that there are no small loops or lines crossing each other. You'll
probably find you've made a mistake somewhere along the way. If you remain
convinced that you have two solutions, save your position, let me know the
details, and I'll investigate further. |
| |
| Could we have some larger puzzles please? |
| If you're a registered user, you should see a link to the 'Beast Of The
Month' on the home page. This is a 40x30 puzzle which you can print off
and attempt to solve 'offline'. Because the puzzle is so large, it's not
possible to display it interactively in the same way as the other puzzles
here, so pen and paper is the best solution. |
| |
| If I do a puzzle more than once, will my time be recorded? |
| No. Only the first attempt at solving a puzzle is timed. You're
welcome to do puzzles many times, but it won't have any effect
on the scoreboard. |
| |
| I'm really stuck on a puzzle. Can you help? |
| No. Try fixing your position and experimenting with lines or crosses
in various places. For example, try putting a line next to a '1', then
follow the consequences of that move as far as you can. If it results
in an invalid board position you can reset back to the fixed position
and you now know that a cross must go in the space where you tried the
line. Often you'll again be left with an indeterminate position, in
which case you'll have to reset back to the fixed position and try
something else. |

| Aren't these puzzles just copies of the Japanese 'Slither Link' puzzles? |
| 'Slither Link' was the inspiration for this web site, but none of the
puzzles are copied - they've been created specifically for this site. I have
no idea how the Japanese ones are designed, so I devised my own methods
for making the puzzles. I didn't think it would be right to use the same
name for them (and to be honest I don't think 'slither link' is a great
name anyway), so I chose one of my own. Kwon-Tom Loop is perhaps a way of
phonetically writing 'quantum loop', which may be a play on 'quantum leap'.
'Quantum' can be defined as the smallest discrete quantity of some physical
property that a system can possess, which might describe the route the
line takes around a solved puzzle. Then again, it might just be an
interesting sounding name. |

| What are some of the technical implementation details for this web-site? |
| The site is hosted at LunarPages.com,
with domain name registered via 123-reg,
and written in PHP, with a
MySQL database holding all the puzzles and
player information. The forums are also custom written for the site,
partly to avoid potential security issues, and also to allow site-specific
functions to be used. Puzzles are displayed and solved in JavaScript,
mainly because it's in most modern browsers and quick and easy to use.
The puzzles themselves are designed off-line, and uploaded to the web-site
several weeks in advance of "going live". |
