Do not want to think long over puzzles, prefer a fixed time for the solution, get and sign, before you play Quick Sudoku. In the upper left corner the timer starts counting, as soon as you put your first number in the selected cell. You will not play more than the designated time, but a quick completion before the end of the period is welcomed. At the bottom of the horizontal panel are the numbers that you will set in the empty cells, until you fill all the gaps in the playing field. Show yourself, prove that you are clever.
