UNO!™ by Mattel163 put the classic shedding card game on every phone: match the color or the number, drop a Skip at the worst possible moment for someone else, and race your hand down to zero. We wanted that loop without the install or the account, so we built Color Clash, an original card game in the same family that runs right here on this page. Free, no download, no signup. Deal a hand and you are playing in seconds.

How to play
You sit at a table with three computer players and seven cards. On your turn, play any card that matches the top of the pile by color or by symbol. Cards you can legally play pulse gently, so you always know your options. Skip, Reverse, and Draw Two do exactly what they say, and wild cards let you pick the next color from a four-button chooser. Stuck? Tap the draw pile once; if the card you draw fits, you can play it straight away. When anyone is down to one card, the table announces it automatically.
Empty your hand first and you score points from your rivals’ leftover cards. Each day has one shared deal, seeded from the date, so everyone in the world starts today’s round from the same shuffle. Your wins, win streak, and best round score are saved on your device. Nothing leaves your browser.
How it compares to UNO!™
Color Clash keeps the part of the game we kept coming back for: reading the pile, hoarding a wild for the right moment, and the small drama of a Draw Two landing on someone with two cards left. The deck structure is familiar, with four colors of numbers and action cards plus eight wilds, and the three computer opponents play with visible pacing and simple intent. They favor the color they hold most of, shed expensive cards early, and save wilds for the endgame, so rounds feel like decisions rather than coin flips.
We deliberately left a lot out. There is no online multiplayer, no 2v2 team mode, no tournaments, no coin economy, and no friend list. Our card faces are our own design, and there is no penalty-call mechanic; the “last card” warning fires automatically for everyone, including you. A round here takes two or three minutes, which is the point.
When should you get the real thing? The moment you want human opponents. Mattel163’s version is built around live matches, team play, seasonal events, and a progression system that gives long sessions a goal. Our version is the quick solo fix. The official app is the party.

Frequently asked questions
Can I play UNO in a browser?
Mattel163 does not publish an official browser version of UNO!™. The game on this page, Color Clash, is our own original card game built around the same match-the-color-or-number shedding loop, and it runs in any modern browser on phone or desktop. For the official game you need the Android or iOS app.
Is this the real UNO?
No. Color Clash is an original game we built, inspired by the family of color-matching shedding games that UNO popularized. It is not affiliated with, endorsed by, or connected to Mattel or Mattel163 in any way. The card design, rules wording, art, and sound are all our own work, and the download links above point to the official app.
Can I play against the computer?
Yes, that is the whole setup. You face three computer opponents that play at a readable pace with simple, visible strategy: they chase the color they hold most of, unload expensive cards early, and keep wilds for the endgame. There is no waiting for a lobby and no other humans involved.
Is it free?
Completely. There are no ads, no in-app purchases, no accounts, and no data collection. Your wins, win streak, and best round score are stored in your browser’s local storage and never sent anywhere.
Does it work offline?
Once the page has loaded, the game makes no further network requests, so it keeps working through connection drops. For dependable offline play in the official game, note that UNO!™ is an online title and needs a connection for its multiplayer modes.
