This strategy puzzle is a very famous puzzle that was featured in Scientific America. "The tower of Hanoi (also called the Tower of Brahma or the Lucas tower was invented by a French mathematician Edouard Lucas in the 19th century. It is associated with a legend of a Hindu temple where the puzzle was supposedly used to increase the mental disciple of the young priest. The young priest was given 64 gold disks stacked neatly on one of the posts. Each disk rested on a slightly larger disk. The priests' goal was to re-create the stack on a different post by moving disks, one at a time. to another post with the rule that a larger disk could never be placed on top of a smaller disk." (written for Science Buddies by Sabine De Brabandere and published on 麻豆社事件 26, 2017) The online version of the Tower of Hanoi puzzle requires you to do the same as the young priests. To emerge victoriously, you must figure out the least complicated way to move all the disks from one peg to another peg. The catch is that no larger disk may be placed on a smaller disk at any time. 

There is no one way to solve the puzzle. The goal is to solve the Tower of Hanoi in the smallest number of moves possible. 

The object of the strategy game is to move all the disks over to Tower 3 (with your mouse). But you cannot place a larger disk onto a smaller disk.

Whether you know them as network puzzles or circuit puzzles, we've got thousands of unique puzzles here for you to solve. You can play for fun or register a free account and compete against other players for the Circuit Puzzle Hall of Fame!

How to Play
After clicking the Unolingo title above, follow these simple directions. The puzzle grid consists of a series of differently shaped wire segments, lightbulbs, and a battery (the green circle, always in the center of the puzzle). An electrical charge will flow from the battery's terminals out through any wires that are directly connected to it. Your task is to rotate the pieces in the grid in such a way so that every piece of wire and every lightbulb is "electrified", without creating any loops. There is one, and only one, unique solution to each puzzle.

All pieces, including the battery (green circle) in the center, can be rotated. Left-click or tap to rotate a piece clockwise, right-click to rotate it counter-clockwise. The puzzle will auto-submit once the correct solution has been uncovered.

Rules of Play
1) Every wire section and every lightbulb must be electrified.
2) All ends of the circuit must terminate in a lightbulb.
3) "Loops" are not allowed in the circuit. A "short circuit" spark will appear whenever a loop is detected.

Futoshiki is a board-based puzzle game, also known under the name Unequal. It is playable on a square board having a given fixed size (4x4 for example).

The purpose of the game is to discover the digits hidden inside the board's cells; each cell is filled with a digit between 1 and the board's size. On each row and column each digit appears exactly once; therefore, when revealed, the digits of the board form a so-called Latin square.

At the beginning of the game, some digits might be revealed. The board might also contain some inequalities between the board cells; these inequalities must be respected and can be used as clues to discover the remaining hidden digits.

Each puzzle is guaranteed to have a solution and only one. To indicate a move, click the desired square and select a digit or the delete sign (X); you can also use the digits on your keyboard (in this case, the digit 0 is equivalent to the delete sign).

For tips and tricks, you can check out our tutorial: how to solve a Futoshiki puzzle.

Examples of sets:
1) color: different on each card, symbol: the same on each card (oval), number: the same on each (two), shading: the same on each card (solid)

2) color: different on each card, symbol: different on each card, number: different on each card, shading: different on each card

It’s not a crossword. It’s not some extreme version of tic-tac-toe. So what is KENKEN and where did it come from? Simply put, it’s a grid-based numerical puzzle that uses the basic math operations—addition, subtraction, multiplication, and division—while also challenging your logic and problem-solving skills. By altering the size of a KENKEN grid, from 3 x 3 up to 9 x 9, and employing different combinations of the math operations, five different difficulty levels can be generated, and a seemingly endless number of puzzles. (And many players seem determined to try them all!) In a way, KENKEN is like a game of pool or even chess: The more you think ahead to your next move and consider all the possible outcomes, the better you’ll get—and the smarter you’ll become!
