Full Rules

Your task is to move the pegs one at a time to transform the starting arrangement into one where all the pegs are placed in holes of the matching colour. The grey holes at the top of the board are used as temporary storing places during the game - but space is limited and every move counts.

Your goal is to make the transformation in the least number of moves, according to the following two rules:

1) You can only move a peg from the top of one column of pegs to the top of another. This means at no time will there be an unfilled hole in a column.

2) If two pegs of the same colour occupy the top two positions in a column and these are moved on consecutive turns to another column that also has the same colour peg at the top, this is a "double play" in which the second move is free and does not increment the counter. The line underneath the move counter shows how many double plays you have made.

To start, simply click on any top peg (the cursor will change to a pointing hand when you hover over a peg that can be moved). You will then see up to four holes are highlighted (these will be four grey holes on the first turn), giving you every legitimate move for the selected peg. Click on one of the highlighted holes, and the peg will be moved to it. The game ends when all the coloured pegs are lined up in the matching coloured holes.

It will quickly be appreciated that arranging the pegs to maximize the number of double plays is the key to obtaining the lowest counts. If your final count is over 30, try again. A score of 29 or 30 is good while 28 is excellent. A score of 27 represents the current world record for this particular transformation. If your score is 27 or lower please e-mail us and, once we have verified your score, we will publish your name with your city and country so you can revel in being a world champion!

Transformation is a compulsive game and comes with serious bragging rights! Can you get a better score than your friends? Let them know how well you did and see if they can beat your score.

This online game is based on Brain Trainer by Peter Pan Playthings, published in 1975, which can be purchased from our Retroactive Vintage Games Store. The game was designed for two players and came with 56 different transformations.

You can test you mental agility with two other transformations: Game 1 | Game 3
