Brainy Gamer has an interesting reflection on old puzzle games and why their style of gameplay seems to be a dying art. According to the author modern gamers seem more interested in combat and seem to have lost the patience for difficult puzzles. "Despite my fondness for the adventure games of yore, it appears the days of puzzles in narrative games have come and gone. Puzzles - especially the serial unlocking variety found in the old LucasArts games - seem to have become a relic of a bygone era. Where they once provided a necessary ludic element to a—clever and often complex narrative - designed to add challenge and force the player to earn his progress through the story - few modern players have the patience for such challenges anymore."

Bryan writes "The number of moves necessary to solve an arbitrary Rubik's cube configuration has been cut down to 23 moves, according to an update on Tomas Rokicki's homepage (and here). As reported in March, Rokicki developed a very efficient strategy for studying cube solvability, which he used it to show that 25 moves are sufficient to solve any (solvable) Rubik's cube. Since then, he's upgraded from 8GB of memory and a Q6600 CPU, to the supercomputers at Sony Pictures Imageworks (his latest result was produced during idle-time between productions). Combined with some of Rokicki's earlier work, this new result implies that for any arbitrary cube configuration, a solution exists in either 21, 22, or 23 moves. This is in agreement with informal group-theoretic arguments (see Hofstadter 1996, ch. 14) suggesting that the necessary and sufficient number of moves should be in the low 20s. From the producers of Spiderman 3 and Surf's Up, we bring you: 2 steps closer to God's Algorithm!"

Tovok7 writes "Free software instant messengers have long been lacking the support to play games with your friends. The waiting is finally over, because today Pidgin Games was released. It comes as plugins for the popular Instant Messenger Pidgin and is running under Linux and Windows. The special thing about Pidgin Games is that it is written in the new programming language Vala which has a C# like syntax, but compiles to pure C."

An anonymous reader writes "This article suggests that Windows Solitaire may be the most-often played computer game. It's not so much an article about Solitaire, but rather an article about Windows and human nature and socialization. If you play FreeCell, there's a interesting paragraph about its inventor." Can Solitaire really eat up more hours than have been sacrificed to Tetris?

a boy named woo writes "Tired of justifying your gaming addiction? Now you can really help accomplish something while you play... thanks to Howard Hughes Medical Institute researcher David Baker at the University of Washington." In collaboration with others, Baker has designed a game, called "Foldit," with a practical outcome: players manipulate on-screen images of protein chains and attempt to predict their folding patterns. From the article: "'Our main goal was to make sure that anyone could do it, even if they didn't know what biochemistry or protein folding was,' says [co-creator Zoran] Popovic. At the moment, the game only uses proteins whose three-dimensional structures have been solved by researchers. But, says Popovic, 'soon we'll be introducing puzzles for which we don't know the solution.'"

Game Set Watch is showcasing an interesting homebrew game called Trism from semi-pro developer Demiforce. The new game is designed to take advantage of the accelerometer in the iPhone and iPod Touch. While making use of this feature isn't new, this game certainly is pretty high on the simplicity and neat-factor scales. In addition to details about the game the site is also featuring a short interview with the developer.

mlimber writes "Slate has an article up on the best free web games. Just what is needed for testing out that new laptop you got for Christmas." These games are considerably more fun than I thought they'd be -- most of them seem to work well with Firefox on Linux (though some require a Windows-only download). And when Salon says "Ayiti: The Cost Of Life makes the Oregon Trail look like Candy Land," they mean it -- most games don't need to caution you that "if the whole family is dead, you lose."

GamesIndustry.biz, in an interview with PopCap Games chief creative officer Jason Kapalka, reports that the company is apparently a bit miffed at 'imitation games'. Puzzle games being what they are, Kapalka finds the number of Bejewel-like titles on the market frustrating. "Very few games are developed without reference to past games. There's always going to be titles that build on a previous mechanic or game. But there's a fine line between that and very bold-faced rip-offs that aren't adding anything to the game and are just trying to make a quick buck." Over at 1up, editor Ray Barnholt points out that PopCap is a funny company to be making that claim. Several of that group's most popular games are in turn tweaks or imitations of little-known Japanese puzzle titles from the 90s.

geddes writes "World chess champion turned opposition leader Gary Kasparov was arrested this morning while leading an march through Moscow in opposition to Russian President Vladamir Putin. Kasporov is a leader of the 'Other Russia' coalition which has been banned by the government from appearing on TV, and had been denied a marching permit. From the New York Times: 'Essentially barred from access to television, members of Other Russia have embraced street protests as the only platform to voice their opposition ahead of parliamentary elections in December and presidential elections next March. Early this month, Mr. Kasyanov's and Mr. Kasparov's Web sites were blocked, though it was unclear by whom.' Kasparov was later released from detention, though he was still fined for participating in the event."

circletimessquare writes "The New York Times profiles 55 year old Maki Kaji who runs Nikoli, in its article Inside Japan's Puzzle Palace. Nikoli is a puzzle publisher that prides itself on 'a kind of democratization of puzzle invention. The company itself does not actually create many new puzzles — an American invented an earlier version of sudoku, for example. Instead, Nikoli provides a forum for testing and perfecting them.' Also notable is how Mr. Kaji describes how he did not get the trademark for Sudoku in the United States before it was too late. But reminiscent of a theme many Slashdotters will find familiar about intellectual property: 'In hindsight, though, he now thinks that oversight was a brilliant mistake. The fact that no one controlled sudoku's intellectual property rights let the game's popularity grow unfettered, Mr. Kaji says.' Will Nikoli be the source of the next big puzzle fad after Sudoku?"

Fortran IV writes "Registration is open until June 15 for the 2006 Google U.S. Puzzle Championship, to be held Saturday, June 17, 2006—it's 25 or so mind-bending pencil-and-paper puzzles that you have 2-1/2 very short hours to solve. The USPC is a qualifying test to choose 2 members for the U.S. team at the 2006 World Puzzle Championship to be held in Borovets, Bulgaria in October. For a mild taste of the puzzles try the 2006 Practice Test (as has been noted here in the past, if you can't get the Practice Test open you should probably give the real thing a pass!) For more of a workout the real tests for 2005 and 2004 are still available."
