Four Colors FAQ

Four Colors is a free online card game like Uno. You and up to three computer opponents each start with seven cards from a 108-card deck in red, yellow, green and blue. Take turns matching the top of the discard pile by colour or by number, use Skip, Reverse, Draw Two and Wild cards to disrupt the table, and be the first to empty your hand.

It plays the same way. Four Colors uses the same style of 108-card, four-colour deck and the familiar rules — match colour or number, action cards, Wilds, calling your last card, and scoring to a target. It is an independent game and is not affiliated with or endorsed by Mattel, which owns the UNO trademark. Uno itself grew out of the much older game Crazy Eights.

You play against one, two or three computer opponents — two to four players at the table. Choose the number of bots before you deal; your choice is remembered for next time. Fewer opponents makes for faster, more head-to-head rounds.

Shedding games, where the goal is to get rid of your cards, are old and widespread. Crazy Eights, played with a standard deck and eights as wild cards, was popular by the mid-20th century. In 1971 Merle Robbins of Ohio turned the idea into a dedicated four-colour deck with action cards; that game became UNO and made the four colours format famous worldwide.

Each player gets seven cards. On your turn, play one card that matches the top of the discard pile by colour or by number or symbol, or play a Wild and name a colour. If you cannot or do not want to play, draw one card; you may play it if it fits. Tap 1 as you go down to your last card. The first player with no cards wins the round and scores the points left in everyone else’s hand.

Skip makes the next player miss a turn. Reverse changes the direction of play (with two players it acts as a Skip). Draw Two makes the next player draw two and lose their turn. Wild lets you pick the next colour. Wild Draw Four picks the colour and makes the next player draw four and lose their turn.

If you drop to one card and do not tap 1 within about two seconds — before the next player moves — you draw two penalty cards. You can avoid the risk entirely by tapping 1 while you still hold two cards, before you play.

Only the player who goes out scores. They collect points for every card left in the other hands: number cards are worth their face value, Skip, Reverse and Draw Two are worth 20, and Wild and Wild Draw Four are worth 50. The first player to reach 250 points wins the match.

No. Stacking — answering a Draw Two with your own Draw Two to pass the penalty on — is a popular house rule but not part of the standard game. Here, the player hit by a Draw card draws and loses their turn.

Yes. Official rules only allow Wild Draw Four when you hold no card of the current colour and let the victim challenge it. This version keeps it simple: Wild Draw Four can be played on any card, with no challenge step.

Yes. Drawing is always allowed on your turn. It is sometimes the right call — for example, to keep a Wild in your hand for later. You draw one card, and you may play it if it matches.

The starting card is always a number card. If an action or Wild card is flipped, it is shuffled back into the deck and another is turned, so the first player always starts on a normal colour and number.

The discard pile, minus its top card, is shuffled to form a new draw pile and play continues. The deck counter next to the draw pile shows how many cards are left.

The bots — Ada, Milo and Zara — dump high-value cards first, try to stay in the colour they hold most of, keep Wilds in reserve, and save Skip, Draw Two and Wild Draw Four for when the next player is close to going out. Like people, they occasionally forget to call their last card, and you can catch them for it.

Get rid of action cards and high numbers early so a loss costs you little. Hold at least one Wild for the end of the round. Use number matches to steer the colour toward the one you hold most of. When the player after you is down to one or two cards, hit them with a Skip or Draw card. And always tap 1 before you play your second-to-last card.

Your current streak counts consecutive round wins. Losing a round — or starting a new match in the middle of a round you have already played a card in — resets it to zero. Your longest streak is kept separately.

Yes. The table, your hand, and the Draw and 1 buttons all fit on a portrait phone screen without scrolling. Playable cards lift up so they are easy to tap, and a new round starts instantly.

Your stats — rounds played and won, matches won, best round score, and current and longest win streak — are saved locally in your browser, along with your sound and opponent settings. Nothing is sent to a server and there is no account. A match in progress is not saved if you close the tab.

Tap the speaker icon in the game bar or press M on a keyboard. Every sound is synthesized in your browser, and your mute choice is remembered for your next visit.

Each colour carries its own shape mark — red ◆, yellow ●, green ▲, blue ■ — in the corner of every card and next to the colour-in-play label, so you can tell the colours apart without relying on hue alone.

Open Stats from the game bar and choose Reset stats, then confirm with a second tap. That clears all rounds, matches and streaks on this browser. It cannot be undone.
