Put diamond (rhombus of acute angle 60 degree) tiles together to form certain shapes with matching patterns on them.
The object of this puzzle is to put 12 tiles shown in the picture above together to form regular hexagon of edge length 2 units with matching type of arcs at all inner edges (in the picture, only the tile at upper right unmatched). The patterns are equivalent to Dodeca Match (arcs) , but the tiles are not reversible. Also, in the design of the picture, 4 different monochrome pattern of arcs are used instead of using 4 colors. It is also possible to form every arcs to be a part of a circle. This puzzle seems easier than Dodeca Match (arcs).
Put 12 tiles shown in the picture above together to form regular hexagon of edge length 2 units with joining all lines on the tiles to be straight. The tiles are not reversible. The patterns collects all possible drawings of straight lines on a diamond such that a line must cross mid points of edegs. This puzzle is not easy, since a placement of a tile affects placemnt of all other tiles which shares the same line.
The picture below illustrates another variation using the same set of the above tiles. Match edges having no lines with edges having two lines (as if the line refrects at the edges), while edges having one line still meet each other as above (so that lines crossing over that edges to be straigt).
The object of this puzzle is to put 12 tiles shown in the picture above together to form regular hexagon of edge length 2 units with matching colors at all inner edges. The tiles are not reversible. Like the next Diamond Match (I x YOU = ?), the patterns are reuse of that of Dodeca Match (4 colors)
This puzzle is virtually the same as "IZZI-2" by Frank Nichols.
The object of this puzzle is to put 12 tiles shown in the picture above together to form regular hexagon of edge length 2 units with matching colors at all inner edges. The tiles are not reversible. The patterns are reuse of Dodeca Match (I x YOU = ?). Similar to it, the following conditions can be applied:
Like Dodeca Match (I x YOU = ?), the 3rd condition is also hard. In addition, a condition of uniformizing colors on the outer edges of dodecagon can be applied for each conditions (though I have not tried yet).
The object of this puzzle is to put 12 tiles shown in the picture above together to form regular hexagon of edge length 2 units with matching curves at all inner edges. (In the picture, only one edge at right most is mismatched.) The patterns are similar to Diamond Match (arcs), but different. The patterns collects all possible drawings of curves where; (1) a curve connects 2 points on 2 different edges (2) 2 different types of curves are drawn on a tile without sharing the same edge, (3) one end of a curve is shifted to right from the midpoint of an edge and the other end is shifted to left with the same amount (in case of arcs, the radius can be either larger one or smaller one). Note: The condition (3) can be replaced to assigning a direction for curves instead of shifting, with preserving the matching logic, where tiles must be joined with matching direction of curves. Logically, this puzzle is equivalent with Diamond Match (I x YOU = ?) with condition of only letters Y and U must appear.
The object of this puzzle is to arrange the above 27 diamond tiles shown in the picture to form a regular hexagon with matching colors and shape of discs at all inner edges. The tiles are reversible, but the patterns on both faces are not mirror images each other. Instead, like Tri-Match (discs #2), tiles are made as if clipped out from real 4 stacked discs, thus, the top most disc on a face becomes the bottom most disc on the other face for each tile. The 54 patterns on the tiles collects all possible paintings of overlapping 4 discs centered on each vertex of a diamond such that 2 discs on 2 vertices of distance one unit length overlap each other (one disc comes top of the other disc) and have different colors chosen from 3 colors. Like Tri-Match (discs #2), it is not so difficult to match them, but the following additional conditions would make it much harder:
The object of this puzzle is to arrange the 12 diamond tiles shown in the above picture to form a regular hexagon of edge length 2 units with matching colors on the edges of tiles, where each of colored regions must be a hexagon (or part of hexagon at outer edges). The tiles are reversible, where the pattern on the back face is the mirror image of the front face. The 24 patterns on the tiles collects all possible coloring of 3 regions of the diamond divided as in the above picuture with differnent 3 colors chosen from 4 colors.
Arrange the 12 diamond tiles above to form a regular hexagon of edge length 2 units with matching patterns on the edges and make a pattern of the same shapes each consists of a line and 2 caps. The tiles are reversible, where the pattern on the back face is the mirror image of the front face. There exists 24 ways to assign 3 colors chosen from 4 colors arbitrary to the tile's edges with colors at adjacent edges different. The design in the picture connects 2 edges of the same color with an S-curved line so that to append additional condition for pattern construction.
