Object: Repeat the same sequence of 5, 10, or 15 colors randomly generated by the computer.

When you click the Start Game button, the computer will light up a single colored section of the board. Touch or click on the same color, and then the computer will give you a sequence of two colors, starting with the same color.

Each time you are able to repeat the sequence given by the computer, it will repeat the previous sequence and add another color to it. You must then touch or click on that new sequence, as well.

The game ends either when you win by repeating a full sequence of 5, 10, or 15 colors (depending on the chosen level), or lose by not entering the sequence correctly.

Further Controls:

Start Game: This button begins a new game at the chosen level. The first color will flash as soon as you press this button, so make sure you're looking at the board when you click it!

Easy/Medium/Hard Selector: This selector lets you choose the difficulty. In the Easy level, you work up to a sequence of up to 5 colors. In the Medium level, you work up to a 10-color sequence, and in the Hard level, you're challenged to complete up to a 15-color sequence.

Object: Arrange the dots so that no lines cross.

Simply click and hold a dot with your mouse, or touch and hold a dot with your finger, in order to move it.

If you're using a touch device and find you're having trouble moving a particular dot, zoom in and try moving it again.

Also, try and avoid placing the dots too close to the edge, as this may make them hard to move later.

Further Controls:

Check Now!: If 1 or more lines are crossed, clicking this button will tell you how many intersections remain. If no lines are crossed, this button will verify this and advance you to the next level.

Triangular Peg Solitaire

Published on Saturday, November 20, 2010 in , ,

To begin, click the Play Triangular Peg Solitaire button below.

Object: The goal is to finish with one peg.

Jump one peg over another into an empty spot, removing the jumped peg from the board. You can jump along any of the three directions parallel to the outside edges of the board. Just click on a peg and if there's a jump available, the peg will jump. If there's more than one jump available, you'll need to click on a destination.

When the same peg jumps over one or more pegs, it is counted as one move. A move that captures a lot of pegs is called a sweep. After you have solved a puzzle down to one peg, you can try to find a solution with the smallest number of moves, or view the computer's solution to the problem.

Further Controls:

Restart: Resets the game to the starting position with one peg missing.

Set Start: Fills the entire board with pegs. Click on one of them to set the starting vacancy (peg missing at the start). Then begin play as usual, or hit Solve.

Back: Take back the last jump (all the way back the start if you like). Very useful if you reach a dead end. You can also back up after pausing a demo or after the demo is finished.

Solve: Solve the puzzle down to one peg (play a demo). You do not have to Restart the game before hitting Solve, it will reset automatically.. When you play a demo, this button changes to Pause, and if you click it the demo will pause, and the button changes to Continue. You can use these controls to halt the solution at any intermediate point. You can even start playing from an intermediate point — however if you play a move manually you cannot continue the demo.

Current Board Menu: Use this to change the size of the board to a triangle with 4 to 24 pegs on a side (10 to 300 holes). If the larger boards do not fit on your screen, set the Board Scale to Small.

Board Scale Menu: For playing the game yourself this is best set to Normal. However to display the larger demos you may want to set it to Small, which shrinks the board by 50% in both directions.

Demo Speed Menu: This sets the time delay between jumps when playing a demo. You can even change this control while a demo is playing, to speed it up or slow it down. Slow, Normal, Fast, Faster and Fastest correspond to delays of 2, 1, 1/2, 1/10 and 0 seconds between jumps. Note that the Fastest delay of zero may not update correctly in all browsers.

Published on Friday, November 19, 2010 in , , , ,

To begin, click the Play Mastermind button below.

Object: The object of Mastermind is to try and discover the computer's secret arrangement of 4 colors. On each turn, you guess the color code, and the computer will tell you, via a response in black and white pegs, how close you are the secret arrangement.

You win if you correctly guess the code in 9 tries or less.

You enter your guess from left to right by clicking on one of the 6 colors next to the board.

The response is given in the form of black and white pegs. For every black peg, there is a correct color in the correct position. For every white peg, there is a correct color in an incorrect position. The response pegs do not, however, indicate to which colors and positions they refer.

Further Controls:

Restart: Begins a new game with a new secret 4-color arrangement.
