Survo Puzzle as a quick game (5x5)

This 5x5 table has to be filled by integers 1,2,...,25 so that each of these numbers appears only once and their row and column sums are equal to integers given on the bottom and the right side of the table. Always start by clicking a cell where to put the next number. This cell will be painted in yellow. Then select the number by clicking a cell containing that number in red. If you select a wrong number, a sound signal will be heard and it gives a clue for selecting the correct number. Each correct selection increases the score sum and a wrong one decreases it. The score will be also diminished by one unit in a second - so you have to be quick when making decisions since the goal is to attain as high score as possible. When the task is completed, you may start a new round by clicking the red square.

Survo Puzzles in this quick mode give excellent practice for logical reasoning, mental arithmetics, and recognition of musical intervals.
