To solve these inventive brainteasers, your brain has to be in tip-top shape. Warm up with some (slightly) easier puzzles: beginning in the left corner of a box with grids, try to reach the bottom right square. You may pass only through the left and right sides of small squares, but not through their top or bottom. And you can't go through the black squares at all. Another challenge involves four dice, all stacked up. Can you find a pattern that lets you figure out how many pips are on the base side? Arrange the "magical dominoes" precisely and mathematically; do the equations to figure out how. There are also unusual card tricks, "cut-it" puzzles that involve reconstructing figures that have been broken up, and three-dimensional conundrums. As you work each one out, you'll feel yourself getting smarter every minute. |

  The puzzle consists of eight contrasting painted cubes - white and black. The unrolling cubes are given in the drawing. It is possible to stick the cubes of strong paper or to take wooden cubes and to paint (or to paste over with a paper) their sides.   It is necessary to collect a cube 2x2x2 with "chess" colouring of each side using eight cubes, as shown in the drawing. Thus the following condition must be observed: it is possible to put cubes to each other only with equally painted sides.

OSM Ball wooden interlocking puzzle on Stand osm is the Czech word for 8. An 8 piece interlocking wooden ball puzzle on a turned wooden stand which will really challenge your dexterity skills.
Adapted from the cube shaped Bar Puzzle designed by Leonid Mochalov (a prolific Russian puzzle designer in his own right) by Jakub Dvorak in 2008, this complex interlocking puzzle is much more difficult than the Egg puzzle and has a unique solution. Precise positioning of fingers from both hands may be required to take the puzzle apart and then you still have the challenge to reassemble it paying particular attention to colour uniformity. Each puzzle piece is made from many smaller complex shaped pieces glued together; finding the correct combination that are not glued, to push or pull to take apart, may be quite difficult. Interestingly, the puzzle was designed first by a Russian, made by a Czech, named by a German (Bernhard Schweitzer), and is now being sold by an Australian; a truly international effort! |

Tigers in a trap

In a square box 5x5 there are 24 bars 1x1 (the place of one bar is free). On four bars the guards are drawn, on the other four bars the tigers are drawn, on sixteen bars pieces of a lattice are drawn.
In an initial position the tigers are in a trap, the guards are outside of a trap (there is an empty place it the centre of a box). Moving bars to the center of a box, it is possible to let out tigers, and to hide guards in a trap. How can you do it? How many bar moves least is required for this? Do you think it is possible to give back one guard to tigers?

  Beginning with the square in the upper left corner, try to find a path to the bottom right corner that passes through every whire square only once. You may move horizontally and vertically, but not diagonally, and passing through black squares is forbidden.
Moving horizontally and vertically, but not diagonally, you must pass through each square once (except for the two exceptions below). Your path may not cross itself, and must form a complete loop, ending where you began.
You connot enter squares marked with an X. You must enter squares with a diagonal line twice, but you may not cross the line. You may move through squares with a diagonal T-shape only once, and only through the “free” half.Again, you may not cross the lines. Let us try to solve the sample puzzle. First of all, taking the rules into accountt, mark the parts of the route that already have conditions. The grid now looks like this: So how do you the path through the rest of the squares? |

Hidden cube

The elements of a puzzle are the cube 3x3x3 (A) and cubes of the same size. In there angular part parallelepipeds are cut out: 1x1x1 (B), 1x1x2 (C), 1x2x2 (D) and 2x2x2 (E).
The task 1. From elements of a puzzle collect a cube so that the small cube (A) is hidden inside the large cube. The task 2. Collect the large cube with the beforehand chosen element inside. The task 3. Scatter cubes on a table, choose any element of a puzzle and fix it in space, and then hide it inside the collected cube. Use for collecting of a "shell" remained elements.
