Free Uno score sheet online, and how to make your own

How Uno scoring works

Most families play Uno one hand at a time, but the official rules keep score. When someone plays their last card, they win the hand and score the points of all the cards left in everyone else's hands. Nobody else scores. The first player to reach 500 points wins the game.

Example: Sam goes out. Alex is left with a 7, a Skip and a Wild (7 + 20 + 50 = 77) and Jo has a 3 and a 9 (12). Sam scores 89. In the score keeper, type 77 for Alex and 12 for Jo, put 0 for Sam and tap "Went out?" next to Sam, and it does the adding up. You can play to 200 or 300 instead of 500 for a shorter game.

Your own Uno score keeper

You'll describe the score keeper to a free AI assistant, paste what it writes into a file, and open it in your browser. Then add the game's own rules, the winner, saving and printing, one step at a time.

• A score sheet with a column for every player and a row for every hand
• A "went out" button: type the cards left in everyone's hands and the winner of the hand gets the lot
• Quick buttons for action cards (20) and wild cards (50)
• Standings with the highest score on top, and a winner at 500
• Undo, saving, tap-to-fix for any score, and printable blank sheets

Good for: families who want a longer game than one hand, kids practising their adding up, and anyone who has never been sure how Uno scoring works.

What you need

Build it in five steps

Step 1 gives you a simple version that works, and each step after it adds more. The score keeper at the top of this page is roughly what you'll have once you've done every step. Yours will look a bit different, because the AI writes its own version each time.

1. Ask for a simple Uno score sheet

   Copy this prompt into your AI assistant:

   Copy this promptCopy

   I don't know how to code. Please make me a Uno score keeper that runs in a web browser, for my family to use instead of a paper score sheet.
   
   Requirements:
   - ONE single HTML file (HTML, CSS and JavaScript together), no external libraries, no internet needed. I will save it and double-click it.
   - At the top, a list of players with a name box for each, an "Add player" button (up to 8 players) and a small remove button. Start with two players called "Player 1" and "Player 2".
   - Below, a score table with one column for each player and a new row for each hand. Under each score, show the player's running total in smaller text.
   - At the end of each round, a big number button next to each player's name. Tapping it opens a number pad to type their score. A "Save round" button adds the round to the table once everyone has a score.
   - A "Total" row at the bottom. The HIGHEST total wins, so highlight the highest total.
   - Big, clear, friendly design with a dark background and buttons big enough to tap on a phone.
   
   Please give me the complete file in one code block, then tell me in simple steps how to save and open it.

   Copy the code, paste it into your text editor, and save it as uno-scores.html. Double-click it, type your family's names and add a couple of hands.

2. Give the points to whoever went out

   This is how official Uno scoring works: the winner of each hand collects everyone else's cards.

   That works, thank you. Please change how a hand is scored:
   - Next to each player's score button, a "Went out?" toggle. Only one player can be marked at a time.
   - Each player types the points of the cards left in their hand: number cards are face value, Draw Two, Reverse and Skip are 20, Wild and Wild Draw Four are 50. Add quick buttons for "+20 (action card)", "+50 (wild)" and "0 (went out)".
   - When I save the hand, the player who went out scores the total of everyone else's cards, and everyone else scores 0 for that hand. If nobody is marked but exactly one player has 0, treat them as the one who went out.
   - Show a message like "Sam wins the hand and scores 89."
   
   Send me the complete updated file.

   Always ask for the complete file. Replace everything in uno-scores.html, save, and refresh the tab (F5 or Cmd+R).

3. Race to 500 and crown the winner

   Now it knows when a game of Uno is over.

   Copy this promptCopy

   Please add:
   - A "Standings" list next to the table, sorted from highest total to lowest, with a place number for each player.
   - A thin progress bar under each player's name showing how close they are to 500.
   - When anyone's total reaches 500 or more, the game is over: show the winner in a big friendly message with a "Play again" button.
   - A setting to play to 200, 300 or 500.
   
   Send me the complete updated file.

4. Save the game, add undo, and print score sheets

   Someone always types the wrong number, and someone always closes the tab. This step fixes both, and gives you paper sheets for when you'd rather use a pencil.

   Copy this promptCopy

   Please add saving, undo and printing:
   - Save the players and the game in localStorage after every change, so refreshing or closing the page doesn't lose anything. Add a note saying "Your game saves in this browser only. Nothing is sent anywhere." and a "Clear saved game" button that asks first.
   - An "Undo" button that takes back the last change, however many times I press it. Keep a copy of the whole game before each change to make this simple.
   - Let me tap any score in the table to change it, and work all the totals out again.
   - A "Print" panel with a choice of "A4" and "US Letter" paper, and buttons to print:
     1. A blank score sheet that fills one page, with six player columns (a score and a running total for each), a row for every round, and the scoring rules in a box at the bottom.
     2. The game being played right now, with everyone's scores filled in.
   - When printing, show only the sheet, with no buttons, using a print stylesheet and @page with the right paper size and 10 mm margins. Every sheet must fit on exactly one page.
   
   Send me the complete updated file.

5. Make it look and feel finished

   Last of all, the touches that make it nice to pass round the table.

   Copy this promptCopy

   Please finish it off:
   - Coloured animal avatars for players, which I can change, and up and down arrows to change the order.
   - A strip of player cards across the top showing each player's total, with a crown on whoever is winning.
   - A big celebration with confetti when someone wins, and a "Play again" button that keeps the players.
   - A "Keep the screen awake" tick box using the Wake Lock API, hidden or greyed out if the browser can't do it.
   - On a phone, stack everything in one column, make every button at least 44 pixels tall, and let the score table scroll sideways inside its box, never the whole page.

Quick fixes

Questions people ask

Twist it into something else

Players, rounds, undo, saving and printing work for almost any game with a score pad. Change the first prompt to make:

Your rules, your table, no adding up

Score pads go missing and the adding up always lands on one person. Yours gives the winner everyone else's points the official way, works on any phone or tablet, keeps the game if someone closes the tab, and never sends your scores anywhere. It's also a great first "real" app: buttons, tables, saving and printing, all in one small file you understand.
