How to use

1. Run ListFile. You will be presented with a Directory Tree on the left, and an empty Table with headers on the right hand side.
2. Drag folders from the Tree on to the Table. All files in the folder will be tabulated against the Table header (eg file attributes such as filename, directory etc). There are more than 2 dozen attributes to choose from.
3. Left Click on Table headers to sort.
4. Right click on Table headers separator to insert file attributes from the Table.
5. Query the Table and generate a second Table, based on file attributes or file contents specified in the query. Use and/or logic to construct complex queries. A query may be set as a filter. Any folder dragged from Tree to the Table will be filtered accordingly.
6. Copy files listed in a Table to a folder.
7. Export a Table to an Access, Excel, CSV or HTML file, or to ZIP file.
8. Many more options.

Updated 28 July 2004

Main purpose of this program is to make abstract patterns from a subset of an image. Patterns are beautiful to observe and interesting to analyze. However, what makes a pattern look good is a mystery. Certainly some kind of ordered repetition appears pleasing to eye. The pattern making replicates parts of an image in an organized manner. Even with just using a few of the numerous ways of arranging an image, the results appear pleasing and delightful. A pattern can then be manipulated through filters and special effects for added abstraction.

Filters and special effects can be used on standard image files also.

version 1.0
Updated 21 July 2004

Two-player, strategy game Abalone was invented in 1990 by Laurent Levi and Michel Lalet. The concept of the game is based on the popular Japanese Sumo wrestling.

Layout

The board is a hexagonal field representing the Sumo arena. There are 4 interlaced different size hexagons, where the most exterior hexagon has 5 circular locations at each side. In the middle there is a single location. As a total, there are 61 circular board locations. Each player has fourteen pieces that can rest in these locations. In initial game position Green pieces are at the top three rows, and Red is at bottom three rows.

Start

Starting from the initial configuration, each player takes a turn. During a turn, a player can shift one, two, or three pieces together in any of the six directions, provided that there is an adjacent space, i.e., in line or broadside. Furthermore, whenever a player has a numerical superiority in a line (three to two, three to one, or two to one), during a turn the player is allowed to push the opposing marbles with an inline move.

Aim

Players take turns "pushing" 1, 2 or 3 linearly connected pieces, attempting to push their opponents' pieces off the board. First player to push 6 of their opponent's pieces off the board wins. One of the players can be the computer.

For detailed instructions and strategies for play see numerous Abalone sites on the Web.

A simple game, yet of surprising mathematical subtlety. Complete your chain before computer does.

Layout

Hex is played on a diamond-shaped board made up of hexagons. The number of hexagons may vary, but the board usually has 11 on each edge. Two top and bottom opposite sides of the diamond are labeled red, while the hexagons at the left side and right side are green. One player plays with green pieces while other with red. The players alternatively place one of their pieces on any one of the hexagons, provided the cell is not already occupied by another piece.

Aim

The objective of the Hex game is to complete an unbroken chain of green pieces between the left side and the right side. While red tries to complete a similar chain of red pieces between the top side and the bottom side.

The chain may freely twist and turn. The players continue placing their pieces until one of them has made a complete chain. The game cannot end in a draw, because one player can block the other only by completing its own chain. These rules are simple, yet HEX is a game of surprising mathematical subtlety.

How to play

In this computer game, computer always plays red. Green usually starts first unless overridden. Left-click in a cell to place a green place. If you wish computer to start first, right-click on any cell on the board.

20,000 puzzles of different difficulty levels

Cardoku is a Sudoku look alike with some subtle differences. This puzzle has following rules:

1. A puzzle has a 7x7 grid and a 52-card deck. A puzzle and its solution use only 49 cards.
2. Some cards are already placed on the grid as part of the puzzle. The remaining cards are stacked for use.
3. You are required to place all the remaining cards on the grid, given the following rules:
   • No duplicate numbers in any row or a column
   • A cell cannot have a card suite of the neighboring cells. Neighboring cells are Up,Down,Left and Right.
   • A cell cannot have neighboring numbers of the neighboring cells. Neighboring numbers are +1 and -1 of a number. For example neighboring numbers of 5 would be 4 and 6; neighboring numbers of 1 will be 2 and K, and neighbors of K will be 1 and Q.
     
   • Consider:
        5C
     3D ? 1H
        KD
     Cell in the centre has to be a Spade, and its value cannot be 2,4, 4,6, 2,K, and 1,Q. Also 3,5,1,K cannot be placed being in the same row and column. Therefore this cell cannot have 1,2,3,4,5,6,Q,K. In this case if only 7 is left in the remaining spades, then 7S must be placed in this cell.

FlipFour is a simple math puzzle. A set of white and black cells with numbers are given. When flipped, a white number will turn to black and vice versa. You must flip four cells to get a given sum for all white numbers. Each puzzle has a unique solution. Puzzles come in 9 different sizes. This puzzle appears deceptively easy but require considerable mental maths to solve. This is how you solve a puzzle on screen:

1. Examine the numbers displayed, with white or black background
2. Now consider how to get a required sum of white numbers
3. Certain whites may have to be flipped to black (for not to be included in the sum) or some blacks should be whites (to get added to the sum)
4. Then click on a cell to flip, a black number will flip to white and vice versa. Sum of the white numbers will be updated accordingly.
5. You must flip four different cells (no less no more). For example if in a puzzle, the current and the required sum of white cells is same, user cannot click a cell four times to solve.
6. Click on any place outside the grid to undo a flip
7. Running total is given at the bottom right of the window
8. You can also use arrow keys to get to a cell and press Spacebar or Return to flip the colour. Press Backspace to undo the previous flip.

A magic square is an arrangement of the numbers from 1 to n^2 (n-squared) in an nxn matrix, with each number occurring exactly once, and such that the sum of the entries of any row, any column, or any main diagonal is the same. It is not hard to show that this sum must be n(n^2+1)/2.

Sometimes the magic squares above are called 'normal' squares, where cells are filled with numbers 1 to n for a grid of size n. Another set of magic squares is where a cell may be filled with any number, with the sum of rows, columns and diagonals being a pre-selected number.

This program computes 'normal' as well as the 'variable' types of magic squares. Following options are provided:

• Grid Size can be 3 to 50. Note that larger grid sizes will take a long time to solve
• Solve - Auto, computer will calculate the MagicSquare. For variable magic squares, the program uses a combination of random guesses and solution of equations in order to arrive at a solution quickly. Each variable magic square solution is likely to be different. For normal squares a combination of La Loubere and LUX methods are used
• Solve - Manual, a blank grid is presented for user to enter numbers in the grid and solve the puzzle. Right click on a cell to a get drop-down menu for manipulating cell values
• Print - Print the solution and the empty grid for attempting solution on paper. Maximum grid Size that can be printed is 30

Introduction
This program is a simple game using a board layout based on Nash equilibrium (named after John Forbes Nash, who proposed it). This game is not about demonstrating the equilibrium theory or its application. Nevertheless some principles of the equilibrium theory would apply when you play this game against the computer.

Board Layout
A 3x3 matrix contains nine numbers distributed randomly. Player 1 has numbers 1 to 9 in the bottom left while player 2 numbers 1 to 9 are in the to right corner of a cell.

Objective of the Game
Players 1 and 2 move alternatively. Purpose of this game is for a player to maximise its score.

How to Play

1. Player 1 start first by selecting a one of the three rows
2. Once a row is selected, player 2 must select a column in that row
3. Player 2 then selects a column:
   • If player 2 selects same column as the row number (eg column 3 if row 3 was selected by player 1) then the respective numbers in the common row/column are added to player scores and game ends
   • If player 2 selects a column (eg column 1 in row 2 selected by player 1), numbers at the intersection row and column are added to player scores
   • Game continues and player 1 selects another row - then step 2 above follows ...

Program Options

1. Select player types: manual or computer. User can play player 1 or 2 but player 1 always starts the game
2. Select how a game ends:
   • When same row/column are selected (default and normal mode)
   • When only one cell is left. This game would last longer.
3. Board and player colours

ReverSudoku

version 1.0
Updated 20 August 2009

This game is Sudoku in reverse - simpler but with even bigger challenge. Basically a 9x9 grid is already filled in with number 1 to 9, nine times. All you have to do is to identify nine segments of nine cells each, with each segment containing numbers 1 to 9. All 9 cells in a segment must be connected in one chain. Only hint you have is that if a number in a cell and a number in any of its four neighbors (left, top, right and bottom) add to 9 then both cells will belong to one segment. There are no other rules.

How to Play

1. Easy - One out of nine segments is already shown in the puzzle. And there are more of same numbers together in the grid making it easier to identify segment boundaries.
2. Hard - A segment is not ready marked. But there are more of same numbers together in the grid making it easier to identify segment boundaries.
3. Very Hard - No segment is ready marked and there are fewer placements of same numbers together.

1. Create a new puzzle of difficulty level of your choice. You can also load or print one of the 20,000 ready made puzzles (1.1Mb) supplied with this program
2. There are nine colours available to markup a cell for a segment
3. Select a colour by clicking the top right hand button
4. Click on a cell to assign it to a segment. Cell will be painted with the selected colour. Click again to clear a cell.
5. Click Show-9 pairs command button to see which cells must belong together in a segment.
6. When you mark a cell and there is a valid neighboring cell with total 9 then the neighboring cells will also be marked
7. Continue marking cells until you have identified all the nine segments
8. When marking cells, program will verify validity using the following checks:
   • Duplicate values are not allowed in a segment. For example cannot mark number 1 twice in a segment.
   • A cell not linked to a chain will not be marked. For example if you have marked two adjacent cells as red. Now you try to mark third cell which is not a neighbor of the existing two - this is not valid.

Hints

1. Spot 9-pairs and mark them as each pair belonging to same segment
2. Note same numbers next to each other. There must be a segment division line between the two.
3. A number or a set of numbers (other than a full 1-9 segment itself) cannot be isolated. Connect such areas with adjacent segments.
4. Numbers in a segment must be all in vicinity of each other and must be connected horizontally or vertically. Look for shortest route to make a cluster of number 1-9.
5. However the best guide is visual scan and your intuition. Scan, relax and look for patterns of unique numbers together.

Numbers 1 to 9 in four colours are arranged randomly in two stacks. Rearrange these numbers, ascending or descending, in four stacks of four colours. You have nine working places and five reserve places to work with. This game is not easy and requires considerable planning and forethought as you move numbers around.

Rules

1. Draw numbers from the Source Stack into the Working Stack sequentially. Six numbers are ready filled at the start of a game
2. Move numbers around in 9-space Working Stack
3. Drop a number from the Working Stack to one of the four Solution Stacks. The number must be positioned over the stack.
4. A Solution Stack must be filled with numbers of same colour and in ascending or descending order
5. Use 5-space Reserve Stack to hold numbers and use them later in the Working Stack
6. As positions in the Working Stack become empty, draw additional numbers from the Source Stacks
7. Repeat steps 2 to 6 until all numbers from Source Stacks have been moved into the Solution Stacks

How to Play

1. Working Stack: You can move numbers to empty spaces in the row. Left click on a number, move mouse (without drag) to an empty space and left click again. Right click on a number to drop the number to a Solution Stack below.
2. Reserve Stack: Click on one of the empty positions in the Reserve Stack. The number below in the Working Stack will be moved up to the Reserve Stack. Click again to move the number down.
3. Source Stack: Click on number in Solution Stack in the same row as the Working Stack. When a number is shifted, the empty position in the Source Stack can be filled by the next (above or below) number in the Source Stack.
4. Solution Stack: Numbers in Solution Stack must be same colour and ascending or descending value. A number 1 or 9 of any colour may be dropped into an empty Solution Stack.
5. Automove: Program will move valid numbers automatically to a relevant Solution Stack. You can disable automove while shifting numbers in Working Stack. For this purpose left click on a number, move mouse (without drag) to an empty space and Right click again. The number or the numbers between two clicks will be shifted to the empty space without any automove to follow.

A pentomino is a geometric shape formed by adjoining five squares with one another edge to edge. There are twelve unique ways to do this (not counting rotations and reflections). Those twelve pieces (or blocks) are pictured here and make up the "classic" set of pentominoes. Traditionally each piece is named using the letter of the alphabet which most closely resembles its shape. Each of the twelve pentominoes (or blocks) by rotation or flip, can be tiled to make a shape, and a lot of fun with pentominoes revolves around filling or building given shapes. These make interesting puzzles. This program helps you solve existing PentoMinos puzzles as well as compile new ones.

Find the location of number 7 by examining the shift patterns between successive numbers. Each puzzle has a unique solution. Normally one would print a puzzle and solve it on paper at ones leisure. A puzzle can also be solved on screen. The solution requires discovering a consistent pattern of shifts from one number in the sequence to the next. Principle is same as discovering the next number in a geometric sequence of numbers. For example next number in sequence 1,3,5,7 is 9 (increment of 2), or, 1,3,7,15 will have 31 as next number (multiply a number by 2 and add 1). However Whereris7 puzzle is a little bit more complicated as numbers have two dimensional patterns. Complicated patters can get rather complicated requiring considerable analytical prowess to solve this puzzle. For solution on screen:

1. Click on a number to see the pattern leading to the next number
