Solitaire is as solitaire does, but sometimes a version of the classic card game appears that makes it feel fresh and interesting all over again. Enter World of Solitaire, a sleek and highly customizable version of solitaire created by Cosmic Realms. It's the next best thing to sitting down with a deck of cards, only now you can sneak in a game or two while you're at work.

The numbers are falling! Fortunately, you've got the fundamental theorem of arithmetic on your side! In Prime Shooter, a math game of prime numbers created by Philip Dorrell, destroy prime numbers directly, or reduce composite numbers by dividing them by prime factors less than 20. Each number you destroy scores you one point, and the numbers get larger and fall faster as your score goes up.

Get Hostile is an abstract strategy game based on the board game Acquire. Like most great strategy games of its kind, Get Hostile packs an enormous amount of possibilities into surprisingly few rules. The object is simple: finish with the most money. However, there are many ways to do this, and not every strategy fits every game.

In the browser-based HTML game, Slave Hack, you take on the role of a vaguely tech-savvy Internet addict who has now decided to make a living out of his/her own talents. If your ethics do not prevent you from pretending to infiltrate other computers to use them as spam relays, warez-sharing nodes, or even as tools to bring down an enemy's computer with a massive DDoS attack, then you are excellent material for the world that is portrayed in Slave Hack.

Geosense is a multiplayer geography game, created using DHTML and Ajax, that can also be played alone. The game itself is all about location and consists of 10 or 20 rounds, each of which involves clicking on the map where you think the given city is located. You receive points for speed and accuracy, although the latter is given more weight. Be careful, you just may learn something.

Sudoku Craving is a great resource for sudoku addicts looking for their daily logic fix. The interface is clean and elegant and, in addition to keeping track of your personal performance on each puzzle, comment boards and high score charts encourage community participation and competition.

Ah, the rural life. Nothing but vast expanses of farmland, the occasional sounds of the barnyard animals, and life-shortening, back-breaking manual labor. But Funny Farm, by Igor Naverniouk, is distinctly different than the farmer lifestyle. This word association game starts on the farm, but quickly branches out into greener pastures.

An adventure game in the classic sense of the genre, as well as in a more low-tech DHTML implementation, the Mystery of Castle Wildenburg combines original photography of Germany's deep woods with the cartoon drawings of artist Aurèle Mechler, which together produces a unique visual appeal to this engaging and compelling Web-based game by Jörg Jochims.

Hunt the Wumpus, by Gregory Yob, was one of the very first ever computer games back in the days of mainframes and punched cards. This version was created by Brian Newtz using an interactive fiction engine he built in PHP, called pFiction, which he hopes to release as open source someday. In the meantime, and to get your pfix of classic computer gaming, you, too, can Hunt the Wumpus.

A fellow graduate of RIT, John Resig, has developed an awesome little Javascript library, called jQuery, that takes much of the chore out of client-side programming and makes it fun. Learning to use jQuery took just a couple of hours and I have already rolled out the first site features that make use of it.

A rather ominous and forboding title for a mysterious game that just popped up a few days ago. Tag this one under "riddle" as it is an HTML-based puzzle game for which answers to on-screen riddles are entered as URLs into the address bar of your browser to advance. But time is ticking.

Another brilliantly intricate and well-designed puzzle game from Rob Allen, this one with similarities to classics Rogue and Lode Runner. Use the arrow keys for movement and navigate the player character (I) through each level to collect all of the gold (£) and then make it to the exit (E) safely. Complete with level editor to create your own level designs!

Ryan Dewsbury of Toronto has created this multiplayer no-limit Texas Hold'em game, called gpokr, in Java using the Google Web Toolkit (GWT), which is a software development framework for Java developers to create AJAX applications. The latest version even has a Jayisgames table where many fun folks from here have been playing and carrying on. Come join in the fun! =)

Solitaire Craving's interface is clean, smooth and easy to use, but the real draw is the emphasis Lyttle put on community features. Each game has a comments section, and a site-wide ranking system keeps track of each user's number of moves made and total time spent playing.

Sudoku Combat is a browser-based multiplayer version of the popular puzzle game that offers a new experience for those that prefer a more competitive challenge. Just enter a user name, select a puzzle difficulty, and then choose to play against a friend or a random stranger. Then it's a race to the finish.

Gwigle is an online puzzle game that actually teaches you Google search tricks as you play. Each screen shows a few search results along with the search string at the top. One word is replaced with question marks; it's your job to fill it in. It's hands-on education that feels more like you're playing a game than learning useful knowledge.

The Wicked and The Wicked Junior are two online riddle games similar to Dumb: The Game and God Tower. Created by Tay Wei Kiat, the puzzles have an uncanny knack of being so simple they're complex. The answers are usually right before your eyes, yet you'll find that each time you'll be stumped for half an hour.

Brucker writes: "Hey, anybody playing that puzzle game that links in to Lost?"

For the better part of the last five years, alternate reality games (ARGs) have fallen into two categories: large, corporate-sponsored advertising campaigns, or smaller, player-run games. Starting last year, however, Mind Candy Design made the first concerted effort to break the mold: an entirely self-sufficient yet wide-ranging ARG named Perplex City.

Travian is a browser-based, massively multiplayer, quasi-real-time strategy game, developed and maintained by a German team dedicated to its upkeep. The goal is to build up economic and military power through the development of land and construction of buildings and armies.

Legend of the Green Dragon is a free, browser based homage to, and extension of, the Legend of the Red Dragon, an original and humorous RPG from the golden years of modems and BBSes.

Dumb: The Game is a free online puzzle/riddle game that requires only a browser to play. Much like God Tower and a bit like Not Pr0n, Dumb pits you against a series of riddles and puzzles armed with only your brain and Google. As you struggle through, you'll definitely feel at least a little bit dumb. Thankfully a bustling community of players are there feeling just as lost as you.

With apologies to those on Macs and non-PC computers, I simply had to follow-up the jaw-dropping visuals of Triglav with another creation by the same team. In fact, it was this captivating clone of classic Breakout gameplay that led me to the SmokymonkeyS site to begin with.

Triglav is a single-player action RPG for IE browsers in which the object is to make it to the top of Triglav Tower, which is 50 floors high. It is an exquisitely detailed effort by SmokymonkeyS and composed in DHTML. Overall the game is an amazing accomplishment, and is truly one of the finest browser-based games I have ever seen.

Frappr, which is short for Friend Mapper, is a new Google Maps powered site that lets you map the zip codes for locations of anything you like, even a group of people such as the visitors of this site. So, why don't you add your zip code, and a nickname that you go by here, to the Jayisgames map and we'll see how many different countries are represented and where everyone who visits is from, hmm?

With the hype for Microsoft's brand new console in full swing, a new site has popped onto the Web games scene promoting the March, 2006, launch of the Xbox 360 in Australia and New Zealand. 063 xobX is a mostly HTML-based puzzle game of ten (10) levels that also includes some Flash-based elements.

The Enigma Puzzle is a sequence of riddles played in the same way as other games like it: Each one of its levels presents an HTML page with clues that you must use to figure out how to get to the next one.

Although not a game, this is just too much fun not to share. Behold the magic of the Blue Ball Machine. Watch the tiny blue balls make their way around the huge machine. And the music that goes along with it is perfect. Rube Goldberg would be very pleased.

For those who prefer a bit of a mind-bender over an action oriented game, Ankh follows in the same footsteps as not pr0n, God Tower, and various other password puzzles. In fact, this game was created by the very same person who created not pr0n. With Ankh, the author used nicely rendered scenes from an upcoming 3D adventure game set in ancient Egypt as backdrops for the game.

Urban Dead is a fantastic and superbly original MMOG that was created by Kevan Davis. To put it simply: it is a text-based zombie survival game that runs in any browser. Even if this sort of game isn't usually your thing, I'd thoroughly encourage you to give it a go, as it's an extremely original and absorbing experience.

Here is a unique opportunity to get started with a brand new game just entering an open beta stage. The name of the game is llor.nu, which is also its Web address, except I'm not sure if that should be pronounced "LORE-new" or "un-ROLL" as the name implies.

As I enter Guano Junction inside the Bat Hole, I check my equipment. Chef's hat? Check. Rubber axe? Check. Frilly skirt? Check. Dirty hobo gloves? Check. Pine-Fresh air freshener? Check (well, one can never be too careful). I am ready for anything.

Let Swarm take you back to the golden days of classic arcade shooters with this fast-paced and addictive DHTML action game from Brent Silby. Like its name implies, bugs swarm onto the play field single-file, as in the classic arcade game Galaga, and begin infecting solar cells. Protect the cells by shooting the bugs to kill them off. You may also shoot the cells to disinfect them and earn additional points.

Sudoku is a popular puzzle game that began in Japan and has subsequently spread like a wild fire throughout the rest of the world. Similar in form to a crossword puzzle, the game is played using numbers only. There is no math involved, just the correct placement of the digits into every row, every column, and 3x3 square.

Brent Silby has created one of the coolest arcade games I have played in a very long time. Think retro-cool as in Galaga, Defender, Centipede and Robotron, and you'll be close to what the action is like in surely one of his best games to date. This game is 100% pure, turbo-charged DHTML! How cool is that?!

Almost twenty years ago, I would often play a solitaire game on the Mac called Shanghai that used Chinese Mahjongg tiles for play. Created by Brodie Lockard and released by Activision in 1986, Brodie is credited with the original idea, programming and artwork for the game. Since then there have been many clones and copycat versions, but most still ...

More kittens than you can shake a stick at. And while this doesn't particularly seem even remotely concerned with games at all, there is actually a whole series of cat games next up in the queue. That, and I'm really missing having a cat around and when I came across all these cat games and kitten pics, well... I just had to share them. Click. Upd...

Tino Zijdel of The Netherlands, aka Crisp, has created a remake of the classic game of Lemmings, originally developed by DMA Design, and coded it using JavaScript and DHTML! The game is beautiful and works very nicely if you have a recent browser (Mozilla, Firefox or Opera) and a 500MHz+ CPU.

Scott Shiller is a Javascript and DHTML wizard and to prove it he has recreated the classic arcade hit Arcanoid with all original levels. There is also a level editor with which you can create your own levels and save them for others to play. The interface is slick and simple, and yet looks more like an application program running than code in a browser window. Amazing client-side programming.
