Stellargrams

Dive into a Stellargram, where hexagons hold the key to cosmic success! With just six numbers and boundless possibilities, you'll navigate a galaxy of mind-bending challenges.

Movie Quote Hanjie

The numbers at the top and side of this nonogram puzzle indicate squares - or groups of consecutive squares - that are to be shaded in. For example the numbers 5,3 tell you that there is a group of 5 and a group of 3 squares to be shaded, with at least one unshaded square between them.

Once you have identified and shaded all the right squares, the remaining letters will spell out a quote from a famous movie.

Hanjie

The numbers at the top and side of this Hanjie puzzle indicate squares - or groups of consecutive squares - that are to be shaded in. For example the numbers 5,3 tell you that there is a group of 5 and a group of 3 squares to be shaded, with at least one unshaded square between them.

Once you have identified and shaded all the right squares, a picture will emerge.

Shikaku

Divide the Shikaku grid into rectangles. Each rectangle must contain a single number, and that number must describe exactly how many boxes there are in the rectangle.

Masyu

Draw a line around the grid that passes through ALL the black and white dots before joining up with itself to make a continuous loop.

Your line can pass through or turn left or right in empty squares, but there are rules for squares containing dots. Your line cannot cross over itself, branch o , or go through the same square twice.

Missing Link

So that the grid follows a logical pattern, what exactly should occupy the squares at a, b and c?

Safecracker

To open the safe, all 20 of the buttons must be pressed in the correct order (which is indicated by the numbers and directions on the buttons) before the “open” button is pressed. What is the rst button pressed in your sequence?

See Saw

Each of the five different coloured balls represents a different weight - 1, 2, 3, 4 or 5 kilos. Can you work out which balls weighs what, and how many yellow balls will balance the final scale?

Grid Lock

There is a pattern behind the placement of the shapes and colours within the grid. Can you identify the pattern, and work out which of the squares below correctly fills the vacant space?

Which Wheel

There are exactly six ways to arrange four colours on a wheel. Which of the wheels: a, b, c, or d, completes the full set of colour combinations?

Sum People

Each of the characters in this sum box represents a different number, with the sum of all the numbers at the end of each row and column. Can you work out which number is each character represents and fill in the question mark?

Minesweeper

Each number in the grid indicates the exact number of black squares that should surround it. Shade the empty squares until all the numbers are surrounded by the correct number of black squares.

Patchwork

This patchwork is in three colours - blue, purple and red. If we don’t want any same-coloured pieces to share a border, what colour will the pieces at a and b be?

Suguru

Each cell in an outlined block must contain a digit: a two-cell block contains the digits 1 and 2, a three-cell block contains the digits 1, 2 and 3; and so on. No same digit appears in neighbouring cells, not even diagonally.

Cell Blocks/Shikaku

Divide the grid into blocks that are either square or rectangular. Each block must frame a single number, and each block must contain the same number of cells as the number it frames.

Venn Diagram

Can you work out which areas of this diagram represent green flags with red stars but no stripes, and red and green striped flags with no stars?

Logic Gates

Puzzles involving boolean circuits and electronic logic gates.

Cubism

This cut-out shape can be folded to make a cube. Which of the four cubes below is the only one it could make?

Block Party

This used to be a big cube made of 125 small blocks measuring 5 by 5 by 5. If all the blocks that are not visible from this angle are present, can you work out how many have been taken away?

Binairo

1. Complete the grid with zeros and ones until there are just as many zeros and ones in every row and every column.

2. No more than two of the same number can be next to or under each other.

3. Rows or columns with exactly the same content are not allowed.
