🎴 UNO

How to play

A two-player UNO against the CPU. You are each dealt seven cards from a 108 card deck and one non-wild card starts the pile. On your turn you play a card matching the colour in force or the value on top, and wild cards can be played on anything. The first to empty their hand wins. With nothing to play, you take cards from the deck until you have one.

• Click a card in your hand — plays it. Legal cards are outlined and an illegal one does nothing.
• Click the face-down draw pile — takes one card. Drawing does not end your turn.
• Colour swatches — appear after a Wild or Wild Draw Four. Pick one and it becomes the colour in force.
• New Game button — reshuffles and deals seven cards each.

Scoring

No points are kept. The counters show both hand sizes and the cards left in the deck. The deck holds one zero and two of each number from 1 to 9 per colour, two each of Skip, Rev and Draw Two per colour, plus four Wild and four Wild Draw Four. Draw Two makes your opponent take two cards and Wild Draw Four makes them take four, drawn immediately. Skip and Rev play as ordinary coloured cards and have no extra effect with two players. The CPU plays the first legal card it holds and picks a random colour for a wild.

Tips

• Play Draw Two and Wild Draw Four while the CPU's hand is small — four extra cards hurt most near the end.
• Keep a wild in reserve. It is the only card guaranteed to be playable and lets you switch colour.
• Count your colours before choosing after a wild; naming your longest colour buys several turns.
• Drawing does not pass the turn, but every card taken is one more to shed, so stop as soon as you can play.
