IQ Brainteasers is the ultimate test of your brain power. Packed with over 300
puzzles, your visual, mathematical and lateral-thinking abilities will be stretched to the
limit. Also included are some Japanese puzzles – Sudoku, Bridges and Slitherlink –
which will really get your brain cells working.
Divided into puzzle types, the sections are not in any order of difficulty – you are just as
likely to find two easy puzzles side-by-side as a more tricky one next to a simple one.
Some will require a degree of mathematical ability, others you just need to use your
eyes, while others still will need some knowledge of words.
For the Japanese section, the principle with Sudoku is simple: all you need to do is
place a number from 1 to 9 in each empty square, so that every row, column and 3x3
box contains the numbers 1–9. There’s no maths or guesswork involved, just logic. In
the Slitherlink puzzles you need to connect adjacent dots vertically or
horizontally, to form a single loop with no crossings or branches. Each number
indicates how many lines surround it. Empty cells can be surrounded by any
number of lines. In the Bridge puzzles each circle contains a number that
represents an island. You need to connect each island with vertical or horizontal
bridges to form a continuous path connecting all the islands. The number of bridges
must equal the number inside the island. There can be up to two bridges between two
islands, and bridges must not cross islands or other bridges.
The solutions are given at the back of each section so you can check your answers, but
try not to peek and complete as many as you can before looking.
