Polyominos

Solve the new tricky number puzzle. No brooding over questions of knowledge, no mathematical magic, logical thinking alone helps to assign the numbers and leads to success. Fill in the free boxes with the number 1-9. Horizontally or vertically adjacent fields with the same numbers form a field. An area consists of exactly so many fields, such as the predetemined number indicating. Two areas with the same dimension may not be neighbors. Two fields with the same predetermined number may belong to the same area. It can give individual areas, where there is no field with a given number belongs. In this field must always be a 1.

Move the mouse over a field. Type a number from 1 to 9 with the keyboard. The game ends automatically when all fields are filled correctly.
