Picma is a japanese solitaire game.

A grid is shown, with 5 rows and 5 columns. At beginning all the cells are white, but under some of them there are hidden yellow cells. You have to guess where the yellow cells are.

To help you, on the left of each row, and on the top of each column, you can see number and distribution of yellow hidden cells.

Number 1 means a single yellow cell; 2 means two yellow cells in sequence, and so on.
If you see "1 2", this means: in that row (or column) there is a single yellow cell, then one or more white cells, and a sequence of two yellow cells. "3 1" means: a sequence of 3 yellow, one white, and a single yellow cell. "1 1 1" means: single yellow, white, yellow, white, yellow.

Looking at combination of row and column counts, you should guess the positions of all yellow cells.

In order to uncover a cell, just tap it.
If your guess was right, the cell color will change to yellow, and you will hear a "toc" sound.
If you guess was wrong, the cell color will change to black, you will hear a "bip" sound, and this action will be counted as a mistake.

When all the yellow cells get uncovered, you will hear a musical sound, and an alert message will notify you the total number of mistakes.
