The idea
Two rivals. One referee. A whole group cheering them on.
The draw favors people who have played less. The challenger chooses from up to three opponents. With three players, the rotation may determine the opponent; the same matchup never happens twice in a row.
The challenger keeps the phone to pick one of three challenges, then passes it to the assigned referee. The referee reads the instructions and starts the challenge. Rivals answer aloud or use the controls shown.
A standard duel is worth one point. The referee selects the winner for spoken answers; number and timing challenges calculate the result. Ties and skipped challenges score no points. The first to 3, 5, 7 or 10 points wins, depending on your setting.

Made to share
Cheer each other on, choose your rival and discover an unexpected talent. Roles rotate and nobody is eliminated. The 20 challenge types mix words, observation, logic, trivia, estimates, reflexes and luck.
One phone is enough and many answers are spoken aloud. With three people, duel and referee roles rotate quickly; in a bigger group, everyone else enjoys the show.
Find a word, estimate a number, judge a duration or choose a chest: each challenge calls on different skills. Read the instructions before every duel.

Good questions
The rules and practical details for enjoying the game together.
No: the game requires 3–12 players. Each duel involves two rivals and a third player as referee. Everyone else stays in the game, with no elimination.
Twenty types include reversed words, opposites, arithmetic, required letters, observation, odd-one-out, trivia, alternating answers, estimates, mental timing, rock-paper-scissors, chests and reflexes. Three options are offered before a standard duel.
Royal duel is worth two points. Rematch brings back a previous opponent. King hunt targets a leading player. Imposed arena picks the challenge at random. Double duel requires two challenge wins and awards one point. These variants appear occasionally, at least three duels apart, and can be disabled before playing.
The referee reads the instructions, starts the challenge and judges spoken answers. Help provides a solution, examples or guidance depending on the challenge. For Mental timer and STOP, place the phone between the rivals so each can press their own button. The result is recorded as soon as a winner is selected, so check before tapping.
A tied or skipped duel awards no points; move on to a new duel. In rock-paper-scissors, however, a tied round is replayed until one rival wins two rounds.

No. dudududuel is free and opens in a connected phone’s browser. Players gather in the same place; this is not remote online multiplayer.
Shall we get together?
One phone. Your group.
