About Visual Match

Visual Match is a pattern-matching game written for Sugar; it is included as part of the Honey collection of Sugar add-ons. The object of the game is to find sets of three cards where each attribute—color, shape, number of elements, and shading—either match on all three cards or are different on all three cards. The current version supports cooperative sharing with multiple players and saving to the Journal.

• Version 18

Visual Match has been partially translated into Spanish and French.

(See our Pootle server for details about how to translate Visual Match into your language.)

More details

• Cards have four different attributes: color, shape, fill texture, and number of elements.

The number version works with prime factors instead of shapes and textures.

The word version works with semantic groupings.

• Play by clicking on three cards to make a match. If it is a valid match, it will be moved on the left (in the blank-card zone.) It will be replaced by new cards from the deck.

• A valid match is defined by cards where each attribute is either the same on each card or different on each card, e.g, all three red cards or one red, one green, and one blue card.

• An invalid match is when two cards share and attribute and the third card does not, e.g., one red and two green cards.

• Matches must be valid across all four attributes. Examples of valid and invalid matches are shown below.

• At the end of the game, all of the matches are displayed in a simple animation.

• As of Version 16, a simple cooperative sharing model is supported.

Everyone works cooperatively to find matches.

Only the initiator of the shared session can start new games, change game type or level.

• Also as of Version 16, the game state is saved to the Journal and restored upon resume. (Note: Restore is currently broken on Sugar pre-0.82.)

Notes:

• The grid layout is arbitrary; there is no need to pick in rows or columns, or one from each column.
• The blank cards on the left are a place to display the most recent match; they can be otherwise ignored.
• A count of number of matches found is shown in the toolbar; when the robot assistant is helping, the count is displayed as two numbers, where the number of matches found by the robot is in parentheses, e.g., 3(2) would indicate that the robot found 2 matches out of a total of 5 (3+2) found so far.
• Visual Match keeps track of your best times (one for Beginner Mode and one for Expert Mode). These times are displayed next to the level-mode buttons on the Tools Toolbar.
• You can select cards using the keyboard:

Top row	1, 2, 3
Second row	q, w, e
Third row	a, s, d
Fourth row	z, x, c
Extra (bottom) row	8, 9, 0

Watch out, because VisualMatch can be very addictive.

Examples of valid matches

The colors, shapes, and shade match; numbers are different.

The numbers match; colors, shapes and shade are different.

Everything is different.

Number Game

Everything is different: colors, prime factors, and representations.

Word Game

The words are from different semantic groups; the colors are different; the font style (bold) matches.

Examples of invalid matches

two of the same colors (red)

two of the same shape (X)

two of the same shade (solid)

two of the same number (2)

When there is no match

On occasion, there is no match among the 12 cards on the grid. If there is no match, three additional cards are dealt along the bottom row as illustrated in the figure above.

Known bugs

There are several known problems with the current version of Visual Match:

• Restore from Journal does not work on pre-0.82 versions of Sugar.
• There are some SVG-rendering problems on pre-0.82 versions of Sugar (resulting in a slightly malformed ✓ graphic).
• Chinese Cards don't display properly on some systems due to a missing font.
• The matched cards disappear when the screen is refreshed.
• There is no indication of whom found the match in group play.
