Lee Krasnow - Puzzle box maker

I stumbled on to “Lee Krasnow” work from a MAKE pod cast that I have included below.

I have always loved these types of puzzles, ring puzzles, box puzzles, ball puzzles. Each year my family would give me a bunch of them for xmas/birthday/etc. 10-15 new puzzles each year some are pretty complex but i have never seen anything as complicated as Lee Krasnow’s Barcode Burr.

Barcode BurrWith so many possible ways to notch the pieces (each of which would yield a different puzzle solving experience) Lee Krasnow decided to design the notches of the Barcode Burr so that the pieces moved in a binary progression. This means that when all six pieces are retracted, the first move is to extend piece #1 which will then allow piece #2 to extend. Once #2 is extended, #1 must be pushed back in before #3 may extend. Because #3 is extended, #4 is now able to move, but not until #2 gets pushed back in place. Of course #2 cannot move until #1 is extended again, and then once this happens #1 must be pushed back in before #4 can finally move.

I didn’t see a price tag on the Barcode Burr but I expect it to be pretty damn expensive.

Song at the end of Portal

Portal is one of the better games I have played this year. A black humor puzzle game thats not repetitive and is actually fun… Fun you remember fun don’t you? the way games use to be before we go all caught up in our new shinny graphics cards.

Anyways here is the ending song. Enjoy

Proving that 3 + 2 = 0

Assume A + B = C, and assume A = 3 and B = 2.

Multiply both sides of the equation A + B = C by (A + B).
We obtain A² + 2AB + B² = C(A + B)

Rearranging the terms we have
A² + AB - AC = - AB - B² + BC

Factoring out (A + B - C), we have
A(A + B - C) = - B(A + B - C)

Dividing both sides by (A + B - C), that is, dividing by zero, we get A = - B, or A + B = 0, which is evidently absurd.

Print your own Yahtzee sheets

After writing about Yahtzee strategies last week I got the nostalgic for the old game and wanted to play it once more. I did a quick google search for some score sheets and didn’t find any that look good or printed well, so I made my own but instead of calling it Yahtzee I called it Roll the dice. Not the most inventive name but it works.

You can print your own roll the dice sheets also available in PDF format.

I’m a great believer in luck, and I find the harder I work, the more I have of it.
-Thomas Jefferson

History of Yahtzee
E.S. Lowe filed Yahtzee as a trademark with the U.S. Patent Office on April 19, 1956. The first commercial usage of the name Yahtzee was a few weeks earlier on April 3. Lowe classified his product as a “Poker Dice Game”.

According to Hasbro, the game was invented in 1954 by an anonymous Canadian couple, who called it “The Yacht Game” because they played it on their yacht with their friends. Two years later they asked toy and game entrepreneur Edwin S. Lowe if he would make up some sets to be given as gifts to their friends who enjoyed the game. Lowe perceived the possibility of marketing the game, and acquired the rights to the game from the couple in exchange for 1,000 gift sets. This story is expanded by E.S. Lowe in the 1973 book A Toy is Born. According to Lowe, the game did not initially do well commercially, since the rules and appeal were not easily conveyed in an advertisement. Eventually he had the idea of organizing “Yahtzee parties” where people could play the game and thereby gain a firsthand appreciation for it. The idea was successful, and enthusiasts quickly popularized the game through word of mouth.

However, the overall concept of Yahtzee traces its roots to a number of traditional dice games. Among these are the Puerto Rican game Generala, and the English games of Poker dice and Cheerio. Most notable is the dice game named Yacht which is an English cousin of Generala. This game is fully explained in The Complete Book of Games by Clement Wood and Gloria Goddard (1940). This predecessor is extremely similar to Yahtzee in both name and content.

What you need to play

How to play the game

On each turn, a player gets up to three rolls of the 5 dice. He or she can save any dice that are wanted to complete a category and then re-roll the other dice. After the third roll, the player must find a place to put the score (though he or she can choose to end the turn and score after one or two rolls if desired). If the resulting combination of dice will not fit in any unused scoring category, the player must place a “zero” in one of the unused boxes. Categories may be filled in any order.
After each player has had twelve turns and all the categories on the score sheet have been filled, the scores are totaled, and the player with the highest total wins the game.

Example game play

A player rolls all five dice resulting with the numbers 6, 6, 6, 3, 3. They could score for a full house without any further throws. But if the full house category is already used they would set aside the three 6s and roll the remaining two dice to try and gain a good score for the sixes category. The remaining dice are rolled again and come up as a 4 and 6. The 6 is kept making four of a kind and the remaining die rolled as the last throw. It is a 6 as well making a Yacht (five of a kind) and scores 50 points which ends a very lucky turn. It is common for a player to enter zero for a category and players often use the 1s for this because it is low scoring.

Highest and lowest score

  • The maximum score of 375 is achieved by scoring 5×1’s (5pts), 5×2’s (10pts), 5×3’s (15pts), 5×4’s (20pts), 5×5’s (25pts), 5×6’s (30pts), Bonus for top row score equaling or exceeding 63pts (35pts), 3-of-a-kind as 5×6’s (30pts), 4-of-a-kind as 5×6’s (30pts), Full House (25pts), Small Straight (30pts), Long Straight (40pts), Yahtzee (50pts) and Chance as 5×6’s (30pts).
  • The lowest possible score is 5. This is achieved by scoring zero in all the top row boxes (and therefore also not getting the bonus), and scoring zero in all the bottom row boxes apart from the chance box. The chance box of course will always have some value. In this case a Yahtzee of 1’s is used to accumulate 5pts. There is no rule that requires a Yahtzee to be scored in the Yahtzee box which would otherwise have incurred a 50pt score.

If you want to know more about Yahtzee strategies and the math behind it you should read Advantage Yahtzee: The Official HandbookVariations of the game

  • Double Cameroon is played in much the same way as Yacht but with ten dice. At the end of a player’s turn the dice are divided into two groups of five and are used to score two categories of the player’s choice. Five rounds are played for the ten categories, which are; categories 1 to 6 and a full house score the same as in Yacht. Little Cameroon (a little straight) scores 21 points. Big Cameroon (a big straight) scores 30 points. Five of a kind (Yacht) scores 50 points.

Yahtzee is also available on GameBoy advanced.

Crokinole - Table top curling

Crokinole_small.jpgCrokinole (pronounced croak-i-knoll, /ˈkɹokɪinol/) is one of the most memorable childhood games that I use to play with my family. Its basically miniature table top curling board but fun (unlike real curling).

There are Crokinole clubs and tournament’s in many major cities that met regularly and tons of books on the subject, even movies, but its still not a widely known game. Most people I talk to have never heard of it or seen anyone play it before.

The 2007 world Crokinole campiaship is coming up in June 2 2007 in Tavistock, ON, Canada.

The earliest known Crokinole board was made by craftsman, Eckhardt Wettlaufer in 1876 (not 1875 as previously reported) in Ontario, Canada. The first registered American patent suggests 1880 as the time when commercial fabrication began - first in New York, then Pennsylvania. The game was probably adapted from a16th century British game called shovelboard. Some people believe that Crokinole was an Mennonite or Amish game this is untrue. Yes, Crokinole has been very popular among many Mennonite and Amish sects throughout Canada because of the fact that the game was viewed as a rather innocuous pastime-unlike the perception that diversions such as card playing or dancing were ‘works of the Devil’as held by many 19th century Protestant groups. Also Eckhardt and his ancestors were Lutherans, not Mennonites.

What you need to play

  • Crokinole board with 20 stones
  • 2 or 4 players

How to play the game

The rules for Crokinole are well defined and can be found on the World Crokinole championships website.

Crokinole is most commonly played by two players, or by four players in teams of two, with partners sitting across the board from each other. Players take turns shooting their discs from the outer edge of their quadrant of the board onto the playfield. Shooting is usually done by flicking the disc with finger, though (rarely) small cue sticks, like those that would be used for billiards may be used. If there are any enemy discs on the board, a player must make contact, directly or indirectly, with an enemy disc during the shot, If unsuccessful, the shot disc is ‘fouled’ and removed from the board, along with any of the player’s other discs that were moved during the shot. When there are no enemy discs on the board, many (but not all) rules also state that a player must shoot for the center of the board, and a shot disc must finish either completely inside the 15-point guarded ring line, or (depending on the specifics of the rules) be inside or touching this line. This is often called the ‘no hiding’ rule, since it prevents players from placing their first shots where their opponent must traverse completely though the guarded center ring to hit them and avoid fouling. When playing without this rule, a player may generally make any shot desired, and as long as a disc remains completely inside the outer line of the playfield, it remains on the board. During any shot, any disc that falls completely into the recessed central ‘20′ hole is removed from play, and counts as twenty points for the owner of the disc at the end of the round. Scoring occurs after all pieces have been played and is differential: the player or team with higher score is awarded the difference between the higher and lower scores for the round.
Play continues until a predetermined score is reached.

Munchkin is one of my favorite card games of all time, anyone that has ever played a d20 system such as dungeons and dragons can relate to this game. Its captures the essence of the dungeon and dragons experience with none of that boring roleplaying stuff.

The game was invented by Steve Jackson an independent board game developer the same person that came up with the GURPS roleplaying system. Steve Jackson games are unique, easy to learn and most importantly fun, hes a genius and a personal hero.

The object of the game is to be the first person to reach level 10 but its not that easy. All your “buddies” are also trying for it too and will do anything to stab you in the back along the way.

The game contains two types of cards, doors and treasure cards. If you kick down a door and defeat the monster behind it you get a treasure, if you can’t defeat the monster you get the bad stuff its that simple.

Monsters include; the 10th level Net Troll, 14th level Stoned Golem, 16th level Wight brothers, 14th Level Unspeakably Awful Indescribable Horror, 6th level pukachu

How to make dice, and a brief history

dice.jpgDie (plural, Dice) - A die is usually a small six sided cube, made of bone, ivory, or most commonly plastic, that is marked with one to six dotes on each of its faces. The cubed dice have the advantage of being balanced in such a way that any side should have an equal chance up landing face up.

The oldest known dice where probably divining sticks made from twigs that where rounded on one side and flat on the other. These divining dice or sticks where used to tell your future depending on what way the land. Pyramid-shaped dice where found in the royal burial tombs of Ur more then 5,000 years ago. Both four-sided, stick, and cubic dice in both ivory and bone flavors have also been found in Egyptian tombs.

teetotum.jpgSometimes a was used instead of dice. A teetotum is a four or six sided top that is spun with your fingers, the sides are marked with numbers or dots so that the number that lands down when the top stops spinning determines the value of the dice. its shape is similar to a dreidel. The teetotum probably originated in Germany during the middles ages and was used to predict the future.

Sometimes in medieval England, dice where thrown on a dice board. The board was divide in to six spaces and a funnel was mounted above the board that the dice where dropped in to it. Instead of using the value found on the dice, they used the value of the squares where the dice landed.

Dice are a essential part of many game, and are needed for everything from Boxing to Yahtzee. A pair of misplaced dice can destroy your plans for the weekend, I know its happened to me many times.

Next time you are stranded without a pair of dice and your guests are already on there way, try printing off a few of these origami paper dice. A little glue or tap and a printer is all you need.

Random drinking game generator

While doing research for an article that I was writing on the drinking game King’s cup. I found that most drinking games all have the same sort of rules. Draw a card, roll a dice then follow the rule associated with that card or dice.

I started a collect all the drinking games rules that I could find that work with a “draw an item and follow the associated rule” type system. Then I put them all in a database and created a script to randomly generate a drinking game.

Manhunt

Today I was told by a friend of mine of a game that recently started in Vancouver called Manhunt.

BASIC MANHUNT RULES:
Manhunt is a hide-and-seek variant. The game starts out with one person, known as the MANHUNTER, who is “it”. After the manhunter has been selected, the FUGITIVES have 120 seconds to hide.

If a FUGITIVE is tagged by a MANHUNTER, she or he is BRAINWASHED and forced to join the side of the MANHUNTERS. At the end of the designated time limit, all FUGITIVES who have not been arrested are declared the winners.

Play occurs within predetermined boundaries. If a FUGITIVE exits these boundaries for any reason, she/he joins the MANHUNTERS. Players are identified as being distinct from the general civilian population by means of a HIGHLY-VISIBLE ARMBAND.

Sounds like an interesting game.

The next match is WEDNESDAY April 25th 2007 @ 7:30 & 8:45 pm @ Waterfront Station. I’m going to see if i can convince a few of my friends to join me its always better with more people.
You can find out more about this game from the official Vancouver manhunt site.
