How a duel works
- Quick duel finds a rival; if nobody comes within 30 seconds, a bot plays you (it aims like a strong player), or tap Play a bot now. Players who are online see a green Join offer while you wait. Duel a friend gives you a room code and an invite link, like a race; your friend taps Have a code? on the Duel card to type it.
- World duel ranking (World ranking on the Duel card): players in order of duels won, then rounds won, then bricks hit. Every duel counts, against a bot too. The results card shows your place after each duel.
- Both players shoot at their own fresh copy of the round's map, one after the other; who goes first changes every round. You have 30 seconds to shoot: a ring above your rocket counts down, and when it runs out your phone fires at a random angle, so your rival never waits.
- The round goes to whoever hit more bricks with their shot; if that's equal, to more points. If both are exactly equal it's a deuce, and the round is played again on the same map.
- You never see your rival's aim or balls, only the bricks their shot hit: outlined in pink on the map (yours in green). Under the top bar you are at the far left and your rival at the far right; the dots next to each name, near the middle, are the rounds won (●●○, first to 3), and a blinking green ▶ marks whose shot it is.
- The results show the rounds won, bricks and points for both players, every round's score, and a replay of each player's shots (the bot's too). Duels don't change the race rating or the world ranking.
A duel, step by step
Open Challenges › Duel. Quick duel finds a rival (a bot after 30 seconds if nobody comes); Duel a friend makes your own room. 
Your duel room has a 5-letter code. Tap it to copy, or Invite a friend. You can also Add a bot. 
Your friend types the code in Join with a code and waits for you to start. 
The tiles sum up the rules: 5 rounds, 1 shot each, first to 3, 30 s a shot. When your rival is in, tap Start the duel. 
Round 1 of 5. When it's your shot, a blinking green ▶ shows next to your name (far left) and Shots shows 1. Aim and fire before the ring above your rocket runs out (30 seconds). 
In the last 5 seconds the ring turns red. 
Time's up: your phone fires at a random angle by itself. 
While your rival shoots, you only see their name and the clock: never their aim or their balls. 
Then it's your shot on your own fresh copy of the same map. The bricks your rival hit are outlined in pink, with how many and their points: that's the score to beat. 
The round is decided: a pop-up shows both players' bricks and points, who won the round and the duel so far (first to 3). It stays for 5 seconds; the map keeps both players' hits (yours green, your rival's pink). Equal bricks? More points wins. Equal on both? Deuce: the round is played again. 
First to 3 rounds wins. The results table has a row for each player and a column for each round (bricks hit, points under them; the round's winner in green), and the last column is rounds won. 
▶ Watch replay shows a player's shots, round by round: the aim, the balls and the bricks they hit.
Hazard duel (from level 75)
When you and your rival have both cleared level 75, a duel becomes a hazard duel: its five rounds come from level 75 up to the lower of your two levels, easy to hard, with those levels' space hazards (and their strength). Against a bot, your own level counts.
