When a work has an excellent premise, it's always interesting to find variations on the theme. Haydn knew it. Beethoven knew it. Now Conceptis gets on board with another in their popular series of browser versions of pen-and-paper puzzles, and this time the focus is on perhaps the most popular remix of that ongoing phenom, Sudoku. Chain Sudoku Light Volume 1, designed with the same care as its fellow works, is a twisty variant that's very, very good.

Battle 60 new levels of Sudoku in this next installment of the Conceptis Light series of puzzle games. Offering up the same mixture of Sudoku puzzles from Mix Sudoku Light Vol. 1, only harder, this set of puzzles is not for the Sudoku novice or easily frustrated. If you're looking for a decent challenge that's the perfect length for a little break, solve a puzzle from Mix Sudoku Light Vol. 2!

Created by Japanese math teacher Tetsuya Miyamoto in 2004, Kashikoku naru Puzzle translates literally as "A Puzzle That Makes You Smart". Hitting that exact right combination of mathematical calculation and logical reasoning, it soon became an international sensation under the name KenKen. As the story goes, "Ken" translates as Cleverness, so KenKen (or, I guess Ken^2) is Cleverness-Squared. That's an apt description for this arithmetic grid-based brainteaser. At JayIsGames, we're always on the lookout for good online versions of pen-and-paper games, and Nextoy has provided with 6 daily, devious, and easily-printable KenKen. Why? Because they Ken Ken Ken!

What's better than having no new logic puzzles from Conceptis? Having plenty of new logic puzzles from Conceptis! Continuing its series of pencil and paper games transformed into browser experiences, Conceptis has just released Basic Logic Fill-a-Pix Light, a minesweeper-esque take on using numbers to create pictures on an empty grid. If you enjoyed Picma Squared, any of the Conceptis Light games, or logic puzzles in general, you'll definitely want to check this one out!

First Sudoku, then Picross, then Battleship... and now Link-A-Pix. Is there any pencil-and-paper puzzle Conceptis can't expertly translate to the flash medium? Painting by Pairs might be a little more obscure than the previous puzzles collected, but B&W Link-A-Pix Light Vol. 1 continues the streak of high-quality logical mind-benders and is filled with nonograms you'll not want to miss.

Sudoku fans should rejoice with this new release from Conceptis. It contains a number of classic puzzles, along with several variations including Diagonal, Irregular, Chain, Odd/Even, and Multi. The sixty puzzles are over far too soon, but with such a well-done interface, the next volume is eagerly awaited.

Researchers agree: playing logic puzzles requires your brain. Exactly what's required of it, they can't seem to agree, but it's the general consensus that the net effect is positive. Enter Strimko, a sudoku-like game of logic that involves placing numbers on a grid. Instead of a dry, angular box, however, you get to work with number chains that snake their way around the grid, adding a nice, flavorful twist to the familiar concept.

Logica is a color and number based puzzler from Candystand. The goal is to follow the instructions each level provides, and sometimes the point of the puzzle is in figuring out what those instructions are. There are three tiers of difficulty with ten levels each, plus a useful five level tutorial. The theme is good, the concept well-conceived and usually the puzzles are clever and a solid application of the concept.

Zerosum is an intense variation on match-3 puzzles, with strict policies on winning and losing but vast opportunities for strategy. Easy to learn, hard to master. Make matches by adding adjacent numbers together, but make sure you don't run out of digits to replace them! It's brain candy, once you get into it, like defusing a bomb constructed by an six-year-old arch-villain.
