 `Basic (required):`
 
 - initially, `body` in the index.html file must be empty (only script tag is allowed), **all necessary elements are generated using JS**
-- the design should be adaptive (or responsive) from _(500px <= width)_. It is acceptable to change the appearance for the mobile version (for example, hide the buttons in the burger menu)
-- the default size of the frame is 5x5. The clues are given at the top and left side of the grid. The sequence of numbers must be logically arranged and help the player solve the nonogram
-- for game field: every 5 cells in a rows and columns should be divided by divider (bold line). For clues: every 5 cells in a **rows** should be divided by divider (for left clues); every 5 cells in a **columns** should be divided by divider (for top clues). Clues should be divided from game field by bold line.
+- the design should be adaptive (or responsive) from _(width => 500px)_. When resizing, all elements must adjust proportionally without abrupt switching, ensuring correct display, full functionality, and no hidden or off-screen content. It is acceptable to change the appearance for the mobile version (for example, hide the buttons in the burger menu). The application should be done in English.
+- the default size of the frame is 5x5. The clues are given at the top and left sides of the grid. The sequence of numbers must be logically arranged to help the player solve the nonogram. Nonograms that have empty rows or columns with zero values as clues should not be used.
+- for the game field: every 5 cells in rows and columns should be divided by a divider (bold line). For clues: every 5 cells in **rows** should be divided by a divider (for left clues); every 5 cells in **columns** should be divided by a divider (for top clues). Clues should be divided from game field by bold line.
 - a player is able to fill in a cell in the grid, using left mouse-click. On a click event, trigger the functionality of changing the color of the grid to dark (black). When player clicks on dark cell - it will change to empty (white).
-- end game when players fill all **black** cells correctly according to the clues. On a successful game solution, display "Great! You have solved the nonogram!" (in case you missed stop-watch implementation)
+- game ends when player fills all the **black** (dark) cells correctly according to the clues and board can no longer be interacted with. Upon a successful solution solution, display "Great! You have solved the nonogram!" (in case the stop-watch implementation was skipped).
 
 `Advanced:`
 
-- the game should have at least 5 templates for easy level (5x5). Players should be able to choose the picture they wish to solve, possibly through a list of items. You might implement it in two ways: either make a list of possible templates with images(solved puzzles) or using template names (without pictures), or using both images and names. User should also easy understand what is the level of image.
+- the game should have at least 5 templates for easy level (5x5). Players should be able to choose the picture they wish to solve, possibly through a list of items. You might implement it in three ways: (1) a list of possible templates with images (solved puzzles), (2) a list using template names (without pictures), or (3) a combination of both images and names. The user should easily understand the difficulty level of the image.
 - a player is able to fill in a cell in the grid changing the color of the grid to crossed-cell(X) using right mouse-click. Context menu should not appear. Filling empty cells with X is not obligatory to win the game.
-- the game can be restarted (reset) without reloading the page (for example, by clicking on button `Reset game`). After clicking the button the level of game and template (picture) should not be changed - it means that only filled cells will be reset. Otherwise the player can change game template or game level (for example, you could implement menu with options) without reloading the page.
-- display the game duration in format XX:XX, stop-watch will start after first click on field (not on clues). "Great! You have solved the nonogram in ## seconds!" is displayed after winning.
-- the game should include sound effects for events such as mark a cell as black, flagging a cell as X, flagging a cell as empty and win game.
-- the staging of the game is saved (for example, using localStorage) by clicking on button "Save game", so that when player clicks on button "continue last game", he can continue playing from where he left off.
+- the game can be reset (restarted) without reloading the page (for example, by clicking on button `Reset game`). After clicking the button, the level of the game and template (picture) should remain unchanged - only the filled cells will be reset. Either implementation, resetting or not resetting the timer, is correct. The player can change the game template or game level (for example, you could implement menu with options) without reloading the page at any time.
+- display the game duration in XX:XX format (minutes:seconds). The stop-watch starts after first click on the field (not on the clues) and stops when the game ends. After winning, if the duration was less than one minute, display 'Great! You have solved the nonogram in ## seconds!'; if it's one minute or more, display 'Great! You have solved the nonogram in ## minutes and ## seconds!'. If right-click (crossing-cell) is implemented, it should also start the stopwatch.
+- the game should include different sound effects for each event: marking the cell dark, flagging the cell with an X, flagging the cell as empty, and winning the game. There should also be the possibility to turn off all the sound effects simultaneously.
+- the staging of the current game is saved (for example, using localStorage) by clicking on button "Save game". This saves only one game, overwriting any previously saved game. When the player clicks 'Continue Last Game,' they can resume playing from where they left off. Crossed-cells (if implemented) are considered part of game staging.
 
 `Additional (to get extra points):`
 
-- dark/light themes of the game. Changing the theme implies a change in the entire color scheme of the application, including the background color, cell colors, counters, buttons etc.

 - implement three levels of difficulty in the game: easy (5x5), medium (10x10), and hard (15x15). Each level should vary in the size of the game board and the complexity of the main template (pictures).
-- the latest 5 win results are saved in the high score table. Table is sorted by time of the game using XX:XX format (for example, using LocalStorage). Every line should include: solved puzzle (either naming, or picture, or both); difficulty; stop-watch result.
-- implement button "random game". When player clicks on button - the random template appears (both template and level must be chosen randomly by algorithm).
-- implement "Solution" button near the field. When player clicks the button - the field will be filled in cells with right solution. Usage of the button doesn't mean winning and will not be recorded into winning table.

+- implement "Solution" button near the field. When the player clicks the button, the field is filled with the correct positions of the dark cells. Flagging the remaining cells with an X is not a mistake. Using this button ends the current game but does not count as a win and should not be recorded in the winning table.
