Every three new Suguru puzzles to solve. Fill in the cages on the grid so that every cage contains unique numbers from 1 to the size of the cage. The same numbers cannot touch, not even diagonally.
Each cell in an outlined block contains a digit from 1 to n (where n is the number of cells in that block). So, a single-cell block contains the digit 1, a block of two cells contains the digits 1 and 2, and so on. The aim is to fill the grid so that no same digit is touching, not even diagonally.
The tectonic puzzle is made up of blocks of different sizes, from one to five boxes. The aim is to fill in the tectonic puzzle in such a way that adjacent boxes never contain the same numbers. Not even diagonally. Adjacent boxes must therefore contain a different number.
The Isis Adventure, often dubbed the world's hardest game, starts as players find a way to open a round puzzle they can hold in their hands.

These are some of the hardest puzzle games of all time.
