# Sliding color match puzzle

I found this sliding puzzle from the famous book “Sliding Piece Puzzles” by Edward Hordern. A rare book. But used copies still available at amazon book store.

This puzzle hasn’t a name. Patented in 1901 by Frank E.Moss. Patent number is US 668386. You can see and download free PDF patent file from here. Thanks to designer.

Why this puzzle is interesting for me? The book say “This is the first puzzle design to include square and rectangular pieces with full movement of all pieces” and also there are another note that say “was it ever produced”. I don’t see before a physical copy of this puzzle and I decided to make one for my self. Now, this puzzle is produced at least one copy. I made this puzzle from 4 mm acrylic with laser cut. Colored spots are pushpin heads I drilled holes and glued inside of holes pushpin heads. Two color spots are made by gluing two half pushpin head. You can make also this puzzle from wood or plywood and instead of using color spots, you can paint wood. An easy to make puzzle with a scroll saw.

In the photo you can see the start position. Pieces should be on the opposite side of the tray to their respective colours. In final position all colors on tiles must match with edge colors. The solution is 70 (76) move.

If you make one, you will be one of the few players of this puzzle in the world.

# Unlucky dice 2

This puzzle is more difficult than “Unlucky dice 1″. I made this puzzle by using standard dice. For making this puzzle you will need 27 dice in three different color. I glued them with a kind of superglue. Each piece has “L” shape and made by gluing 3 dice together. For this puzzle there is 3 different problem.

1. Make a cube. An easy problem
2. For this problem you will ignore numbers and you will try to make a cube so on six face two same color will not be placed on same row or column. Same color may be placed on same diagonal. Inside (non visible ) faces will be ignored.
3. This is most difficult problem for this puzzle. You will try to make a cube so on six face two same color will not be placed on same row or column and in same time same numbers will not be placed on same row, column or diagonal.

Puzzle pieces are here,

But you don’t need make same puzzle with me. First make a cube with 27 dice according to rule 3. After you must find a solution diagram for this cube and take pieces 3 by 3 according to solution and glue dice together without changing their positions. This method may be easier for making this puzzle. An easy to make and very difficult puzzle to solve. An example solution diagram is here.

# Unlucky dice 1

I made this puzzle by using standard dice. For making this puzzle you will need 27 dice in three different color. I glued them with a kind of superglue. Each piece has “I” shape and made by gluing 3 dice together. For this puzzle there is 2 different problem.

1. For this problem you will ignore numbers and you will try to make a cube so on six face two same color will not be placed on same row or column. Same color may be placed on same diagonal. Inside (non visible ) faces will be ignored.

# Wiegleb board

This is my Wiegleb peg solitaire board. Rules are same with peg solitaire played on English or French board. If you didn’t played before, you can learn rules from here. This board contains 45 holes and 44 pegs. For making this board I used a piece of plywood and 16 mm marbles. A wooden pizza cutting board can be used. I made the circular slot around the table with a router. For 16 mm marbles 13 mm holes are good for me. the gap  between two marble is 6 mm. Table diameter is about 280 mm. I painted the plywood with black ink and applied a lacquer finish.

# Mad process S – M -L -XL

In a factory there a huge machine. Maintenance team must change the old gears of this machine with new ones. But gears aren’t easily accessible. And factory engineers decide to use the machine turntable. But there are some problems. Machine turn table turns only 90 degree with missing gears and also some other pieces from gear box enters into the turn table. Now they must find a solution with less possible move.

This puzzle is one of my sliding puzzle designs. Different from classical sliding puzzles. The aim of this puzzle is changing red and blue pieces in correct order. At the center of the board there are a disc with four slot. Disc rotation is limited and can rotate only 90 degree clockwise and after back again counterclockwise. That movement make this puzzle difficult and confusing.

There are four different variation. But two of them is more interesting. First I like describe XL version. This is the version seen on the left big picture. I mounted the clear acrylic top cover. At the center of each pieces there are a small hole that make it easy to play with a toothpick. (I take other photos without a cover because of reflection risk.). This version is the most difficult version. There are three extra green disk that make more difficult it. For this puzzle I count only the quarter rotation of the center disk as a move. Because shifting operations isn’t too much important and also counting only the center disc rotations is easier. I tested it with some friends and they find it very confusing. Some of them, in half way of the solution confuse also which color goes up and down. My solution for this starting to solve always with blue ones on the upside. I played a lot of time. I have a score for minimum number of move. But I will not share here. That may be a shame for me later.

The other variation is S version without any green disc. It’s very easy with 6 empty space at the beginning. But if you search the minimum number of move, this puzzle require a different style of thinking. Differently then other sliding puzzles, instead of thinking sliding operations you must try to use center disk better and keep it busy in each turn.

The other variations with one and two disc has an increasing difficulty.

For puzzle enthusiasts and mathematicians finding the minimum number of move may be a good challenge. I don’t know minimum number of moves as I haven’t a computer analyze tool for this. Also it’s possible to write a java applet and play online or make a mobile device application with four level of difficulty. If you can make you can publish it in anyway that you like.

I made this puzzle from acrylic with laser cut. It’s very easy to make if you have access to a laser cut machine or a scroll saw. I put labels on each pieces for decorating. My puzzles has a clear acrylic top cover. But if you like you can make also an open version. By making one you can play also four variation by adding green discs. If you want make one for you I will add here in a few days laser cutting files (DXF) and assembly instructions with labels for decoration. I made a few design change for better center mechanism for this reason laser cut file is a little different from my puzzle. I made a clear acrylic cover for this puzzle. But this make difficult to play. For playing I prefer an open top puzzle.

# Simitler

The name of this puzzle is coming from a food special to Istanbul/Turkey. This food has a similar shape to donut a made from a dough similar to pizza but the result is completely different from both of them. This sesame covered delicious food is mostly eaten with Turkish tea. This puzzle consist of 12 discs. The aim of the puzzle is putting this discs one to the top of the other and make a tower. I made this puzzle from 4 mm acrylic by cutting with a laser cutter and gluing pins wit a special acrylic glue. If you want make your own you can make from wood. Puzzle pieces are visible from photo.

Short pins length is equal to disc thickness and long pins length is equal to 2 x disc thickness. You can choose disc thickness as you wish. I made also a square version of this puzzle. Square version is easier to make. I made my puzzle from cheap Jenga pieces. You can and glue Jenga pieces together. Puzzle pieces for square version is here.

If you want make your own laser cut puzzle you can download from here my DXF file for laser cut.   This is an ASCI DXF file. Approximately all drawing software can open this file. I used for drawing “Draft Sight”. If you need a SVG file you can open with “Inscape” and transform to svg etc. You will use small rounds that you obtain from holes as pins. For long pins you must glue two round. For gluing pins to correct locations you can glue them according to solution. You can start with first disc and you can put the second on top of first and glue pins to locations indicated by holes.  My disc diameter is 80 mm. You can scale as you wish.

# Push pins diamond

This puzzle is a another simple color match puzzle. The aim of this puzzle is different. You must arrange puzzle pieces into a diamond shape (first row 1, second row 3. third row 5 etc…)  such that no two same color appears in adjacent squares (diagonally and orthogonally).  This puzzle is also easy to make with a wooden stick and some pushpins. For making “L” shaped pars I glued 1×1 sticks to 2×1  sticks. I used 20 x 10 mm wooden stick. You can use similar dimensions according to your materials. I cut them with a hand miter saw, I made some decorative saw traces and mounted push pins. Puzzle parts are below.
