Four Colors is the UNO-style card game that runs straight in your browser. Match a card, drain your hand, beat everyone else to zero. No downloads, no sign-up — just pick your opponents and play.
You can face one, two, or three computer opponents per round. A full game takes under five minutes. That’s the whole pitch.
What Is Four Colors?
Four Colors is built on the bones of UNO the card game a barber from Reading, Ohio named Merle Robbins invented in 1971 to settle a family argument about Crazy Eights. He hand-assembled the first decks on his dining room table, mortgaged his home to print 5,000 copies, and sold them from his barbershop. Within a year he’d sold the rights for $50,000 plus a ten-cent royalty per copy. Mattel bought the game in 1992, and it’s since sold over 151 million copies across 80 countries.
The browser version — Four Colors — launched in 2009 as a Flash game made by Playtouch. It moved to HTML5 in 2020 when Flash was discontinued, and Special Mode was added in 2021. Same rules, cleaner tech, always free.
How Four Colors Works
Each player is dealt a hand of cards. One card sits face-up on the discard pile — that’s your starting point.
On your turn, play any card from your hand that matches the top of the discard pile by color or number. Red 7 on any other 7. Blue 4 on any other blue. That’s the core rule — everything else builds on it.
Can’t make a match? Draw a card from the deck. If that card plays, you can use it right away. If not, the turn passes to the next player.
First player to empty their hand wins the round.
Action Cards — How They Change the Game
Numbered cards keep the game moving. Action cards flip it.
- Skip — The next player loses their turn completely. Strong when an opponent is close to winning.
- Reverse — Flips the play direction. In a two-player game it acts just like a Skip, sending the turn back to you.
- Draw Two — Forces the next player to pick up two cards and forfeit their turn.
- Wild — Plays on any card. You choose what color the game continues in. Pick the color you hold the most of.
- Wild Draw Four — You pick the new color and the next player draws four cards and loses their turn. The strongest card in the game — save it for when someone’s about to win.
The One Rule Everyone Forgets
When you play your second-to-last card and you’re down to just one, you must press the “1” button before the next player takes their turn.
This is the Four Colors version of calling “UNO.” Forget it, and you draw two penalty cards as punishment — the game enforces this automatically, no exceptions.
It sounds simple until you’re focused on picking the right card and you miss the button entirely. It happens to everyone at least once. Play the card, immediately press 1, then look at the board.
Tips for Winning More Often
- Play your number cards first. They only do one thing — match. Keep your action cards until they can do real damage.
- Call the right color on a Wild. Pick whatever color you hold the most cards in, then chain your plays while that color is active.
- Target the player closest to winning. Aim your Skip and Draw cards at whoever has the fewest cards left — not whoever last got you.
- Don’t waste your Wild Draw Four early. Dropping it when everyone has full hands is a missed opportunity. Use it when an opponent is on one or two cards and it ends the round.
- Watch the discard pile color. If an opponent keeps drawing instead of playing, they’re short on that color. Next Wild you play — call it.

Frequently Asked Questions
Is Four Colors the same as UNO?
Very close. The core rules are identical — match by color or number, use action cards, and announce when you’re on your last card. Four Colors is a browser-built tribute to the UNO format, playable for free with no physical deck needed.
How many people can play?
Up to four total — you against one, two, or three computer opponents. You choose before the game starts.
What happens if I forget the 1 button?
You draw two penalty cards. The game enforces this automatically — unlike a real table game, there’s no getting away with it.
Do I need to download anything?
No. The game runs in your browser. Just open the page and play.
Can I play on my phone?
Yes. Tap to play your cards. The layout adjusts to smaller screens and no app installation is required.
What are Wild cards and when should I use them?
Wild cards can be played on any card regardless of color or number. Use a regular Wild to switch to a color you hold lots of. Save Wild Draw Four — which also forces the next player to draw four cards and skip their turn — for when an opponent is one move away from winning.
